EasyBits GO, Skype, and The Crapware Problem

This morning at 9:59 AM local time, a dialog from an unknown app popped up and asked me if it could install Adobe’s Flash player. My reaction is the one everyone should have in response to things like this: Don’t click. Stop and think. I’ve been around for awhile and I’m not stupid. I’d never heard of EasyBits Go and certainly hadn’t installed it on my system. I brought up Windows Task Manager, and sure as hell, there was a process running called easybitsgo.exe. Worse, there was an icon on my desktop that hadn’t been there a few minutes before. And the dialog had a blatant misspelling on it. “Do you wan to install it now?”

Talk about red flags!

I immediately did a search for EasyBitsGo.exe on my system, and found the executable at Documents and Settings/All Users/Application Data/Easybits GO/ There are several subfolders as well. There was an app listed in the Add or Remove Programs applet. There was a folder (dated a few minutes later) called “go” in my user tree under Application Data. It contains some kind of a log. Last and worst of all, there were Registry keys in the HKEY_CURRENT_USER subtree under Software/EasyBits.

Only after gathering that data (and taking a quick look on Google, which showed almost nothing) did I begin removing it. Online postings just a few minutes old verified my suspicion: It had ridden in on Skype. I was using Skype at 10 AM when the dialog popped up. I did not have a browser open, and in fact was not doing anything unusual. (I was editing an Odd Lots entry for Contra.)

EasyBits is a real company, and they created and have been running Skype Game Channel for some years now. I’m not a gamer and hadn’t run across them before, but they have some history, and don’t appear to be malware vendors. (This does not mean that malware could not impersonate them.) Nonetheless, however they had pulled it off, what they’d done was utterly unacceptable: They’d installed a whole app with no obvious connection to Skype without any warning, much less any request for permission.

Too, too much. I may be done with Skype. Still thinking about that. In the meantime, if this happened to you as well, here’s how to fix it, at least under XP:

In Skype, select menu option Tools | Options | Advanced, and un-check Automatically Start Extras. Click Save.
Shut down Skype.
Bring up Task Manager. If the EasyBits GO dialog is still visible, EasyBitsGO.exe is probably running. Kill it. The box will vanish. (Kill the process even if you’ve already closed the dialog.)
Make sure the SkypePM.exe process is not running. If it is, kill it.
Go to the Add or Remove Programs applet and uninstall EasyBits GO. It uninstalls almost instantly, which suggests that nothing is actually being uninstalled. This was the case as best I could tell.
Find the folder tree at Documents and Settings/All Users/Application Data/Easybits GO/ and delete it.
Go to the Application Data folder tree under the user that was active when the damned thing installed, and find the go folder. (It contains some kind of log file.) Delete it.
Go to the Windows/Prefetch directory and look for the file EASYBITSGO.EXE-364DAFD6.pf and delete it.
Search for and delete all instances of ezPMUtils.dll. They may be in different locations depending on your version of Windows.
If you’re comfortable editing the Registry, get rid of the keys at Software/EasyBits as shown in the screenshot above.
Reboot. Theoretically that should do it, but if Skype could push this thing down to countless users without their knowledge once, it could do so again.
After rebooting, I think it might make sense to update your virus scanner signature database and do a full scan on your system.

So whatthehell is going on here? There’s still not a great deal online, but I’m seeing more and more angry people posting every hour. I have a guess: EasyBits paid Skype for the install. This is the crapware business model, in which a company pays a hardware or (less often) software vendor to install stuff that the customer did not ask for, and pays by the install. This is typically trial version software, and the crapware vendor benefits when customers cluelessly upgrade to paid versions.

The crapware business model is why I no longer buy retail PCs, which come so clogged with crapware that they can barely move. I buy either custom-built machines or used corporate machines like the SX280 USFF, which were never retail machines to begin with and came with no crapware at all.

Cheap or free stuff is often less cheap or less free than its vendors imply. Crapware is one reason retail PCs are as cheap as they are. Dell, HP, and the others take a certain profit on each retail PC selling crapware slots. Absent the crapware, the machine would cost more. I buy new custom locally or used on eBay, and the machines are as cheap as new retail PCs and work a lot better. (Why does a four-year-old P4 2.6 GHz corporate box go so much faster than a current Core 2 Quad 3 GHz retail PC? Crapware.)

This is a guess, but it makes sense. Why else but money would Skype do something so absolutely certain to get them crucified in the blogosphere? With my tinfoil hat on I could imagine that certain parties at Skype aren’t happy with being assimilated by the Borg and are getting some parting shots in. It’s too late to foul the deal, but anything that makes Ballmer itch in bad places might be worth it to them.

Finally, if this happened to you, let me know in the comments or by email. It seems like a lot of people got hit with this, at least those running current versions of Skype. What if the entire installed base of current Skype instances pushed EasyBits Go down the pipe and onto user desktops? That would be a freaky thing indeed, and will make them a Mordor horde of enemies. Stay tuned.

UPDATE: I cranked up an old XP SP2 machine with Skype 5 installed this afternoon and so far, the EasyBits install hasn’t happened. Will leave it on tonight and check it in the morning. It may be that the install requires SP3, Vista, or Win7.

Lazarus, Stay Where You Are!

May 6th, 2011

…because when you came forth, you stepped on my bootloader.

I’ve tried to like Lazarus. I’ve tried for years. I can only assume that (as also evidenced by its similarly screwy cousin, Kylix) there is something in the Linux platform that makes Pascal compilers go a little bit whacko.

A few days ago I installed the KDE Fedora Spin in a new partition on my Linux box. It’s been a good education in the Plasma desktop. Plasma is all very blue and cold looking (way too blue for me, in fact, though the default wallpaper is striking) but unlike my first taste or two of KDE 4, it actually works.

So I started installing the software I’m familiar with to begin using it, and somewhere down the list was Lazarus, the Delphi-ish GUI front end for FreePascal. The package available from Fedora was V0.9.28.2, which is considerably newer than the one I have installed on Ubuntu Lucid, and only a little older than the one you can get from the project Web site. After it downloaded and installed all of its enormous pile of stuff, it asked me to restart Linux. I did.

And grub failed to run.

All I got was a blinking text cursor in the upper-left corner of the screen. This is the first time I’ve ever seen grub fail, apart from the well-known habit of Windows to overwrite grub with its own bootloader. (This is why Windows goes in first, if you’re going to have it at all.) I booted the Ubuntu 11.04 live CD I’d burned a few days after it was released, just to see if my MBR had been damaged. As best I could tell it had not, but I’m not good enough at grub’s internals to really be able to tell what was wrong with the software itself. Since I had plenty of free space on the 750 GB drive, I just installed Ubuntu on yet another partition, hoping that its update of grub would put things right. And it did.

So why would installing a compiler and an IDE mess up the OS bootloader? (Anybody?) I don’t have a lot of clues. The copy of Lazarus I installed looks like it works as well as Lazarus ever does, so I can’t assume that something in the installer or the package glitched and overwrote something unrelated. None of the other partitions on the disk were affected, as best I can tell. I’m tempted to install Lazarus under Ubuntu, to see if it will stomp on Ubuntu’s copy of grub as well…but that will happen another day, when I’m not as busy and not so grouchy.

Fedora Spin: KDE Desktop

May 1st, 2011

Sometime back I ran into a concept called Fedora Spins, which are customized Fedora installs with different desktops (KDE, LXDE, XFCE) or a slant in some direction like security, graphics, or games. I downloaded the KDE Spin ISO earlier today, burned it to CD, and this evening (having burned out on ebooks) took it for a…ride. I had 300 GB of free space on my Linux box, so there was no reason not to, and I’d like to get a little better at the KDE Plasma desktop.

Some reactions:

The Fedora partitioner is very good. I did a manual partition operation, and created a new 60 GB partition for Fedora, and a 12 GB swap partition. It helps to know a little bit about partitioners generally, but overall it was intuitive and gave me no trouble.
For some reason, Fedora installs grub with grub’s hiddenmenu option enabled. (It’s conceivable that I accidentally chose that somehow, but I don’t recall being asked.) This means that at boot time, grub’s menu isn’t displayed, and the system boots directly into Fedora. (The system already has Ubuntu Lucid and Windows XP on it.) You can get the boot menu by pressing F10 during grub’s timeout period, but otherwise you aren’t presented with an OS menu at all.
Fedora recognized the existence of my XP partition, but didn’t know what it was. In grub’s menu, XP is therefore listed as “Other.” However, if you select it, grub boots it just fine.
Fedora has a GUI bootloader configuration utility that allows selection of the timeout value and the default OS. However, the utility’s sole window does not have a Save or Apply button. You can make changes, but closing the utility throws them away. Wow. This is a bug, and not a brand-new one.
Unlike Ubuntu, Fedora does not automatically add the initial user account to the sudoers list. So try to do anything rootish like editing grub’s config file gives you that inane message “jduntemann is not in the sudoers list. This incident will be reported.”
Adding yourself to the sudoers list is seriously unintuive, but the best way is probably to use the visudo command, which opens a vi edit window with the sudoers list ready to change. Add USERNAME ALL=(ALL) ALL to the end of the file and save; it’s done. Details here.
Fixing grub requires editing the grub.conf file and commenting out the hiddenmenu option. While I was there, I also changed the description of the XP partition from “Other” to “Windows XP.”
A 2.8 GHz Dell SX280 does not have sufficient graphics chops to run Plasma’s desktop effects. I wanted to see just how slow they were, but within seconds of enabling desktop effects, Fedora disabled them again. I knew that the SX280 wouldn’t run them well from my online research (it’s one reason I’m getting a more powerful Linux box shortly) but I didn’t know the system would simply refuse to run the effects against my wishes. Interestingly, Ubuntu’s GNOME desktop effects subsystem works on the same machine.

Overall, getting to a usable configuration with Fedora is a lot more screwing around than with Ubuntu. But once done, it works well. More as I experience it.

Here’s a nice graph of the smoothed sunspot number for the last four solar cycles (21-24.) Our current Cycle 24 is still young, but it stands fair to be the weakest solar cycle in 200 years. It may mean nothing, but 200 years ago we saw cycles like that frequently and were in the worst part of the Little Ice Age.
Darrin Chandler pointed out Maqetta to me: an HTML5 WYSIWYG Web editor, free and open-source. And from IBM, yet. Haven’t tried it but hope to in coming days. Has anybody else played with it at any length? I use Kompozer for Web work right now, and it’s not evolving very quickly, let’s say.
And what we may need more than Maqetta for Web pages is Maqetta for epub ebooks. I remain appalled at how much kafeutherin’ it still takes to do an epub with a cover image and even the simplest forms of paragraph differentiation. (Like no first indent to indicate a new scene in a story.) People continue to hand-code ebooks. This is idiocy to the seventeenth power.
Sometimes you read a short, casual mention of something in a book or article, and the weirdness of it doesn’t really hit you. So stand ready for some pretty boggling astronomical weirdness: A 400-meter asteroid that moves in a horseshoe-shaped orbit. And guess who’s in the gap of the horseshoe?
At our most recent nerd party, my new friend Aaron Spriggs mentioned Chisanbop, a method of finger arithmetic created by the Koreans and little known here in the US. This is very cool, and would be extremely handy on fictional planets (like my own Hell and the Drumlins world) where electronic computation either doesn’t work and hasn’t been invented.
A brilliant new method of imaging underground structures like magma plumes shows that the Yellowstone supervolcano is bigger than we thought. The imaging is done by measuring electrical conductivity in the rock rather than the transmission of physical (seismic) vibration. The images give us no additional information on how close (or far) we may be to another eruption, but it may help us to interpret what little data we already have.
Hoo-boy, here’s a problem I don’t think anyone anticipated in the wake of Japan’s recent catastrophic tsunami: Safes full of (soggy) money washed out of individual homes are now washing up on the seashore.

The Inexplicable Pirate Box

Jan 31st, 2011

by Jeff Duntemann.

I’m still on the long climb back to functionality and can’t do much computing because the current bug has hugely irritated my eyes. However, I did want to call quick attention to one more thing in the pirate universe before going back to bed: David Dart’s Pirate Box. I got the tip from the Jolly Pirate a couple of days ago, and most of the gadget blogs have now picked up the story. It’s a make-it-yourself wireless filesharing node in a pirate lunchbox.

Lesse here: You carry this into a crowded coffee shop so that people can connect from their laptops and smartphones and download whatever pirate goodies are in the box, at least until somebody calls the Bomb Squad.

Ok, I’m just funny that way. But read through the DIY, and ask what I’m asking: Isn’t this a lot of fooling around just to create a wireless file-sharing node? Even a five-year-old beater of a laptop can run Debian and a file server, and software router apps are routine. Furthermore, a laptop looks like a laptop, and when there’s a dozen people at Panera running laptops, it’s a little less easy to tell who’s the pirate.

Unless that’s the idea. This certainly seems to be more about cachet than practical piracy. I’m reminded of warchalking, a silly near-hoax that was getting people’s twickers in a nist back in 2002 or so: marking the locations of wi-fi networks on the sidewalk in chalk, god help us, as though there were no other way to know something was there.

I have the late Harry Helms’ books about pirate radio and I think I understand the psychology. It’s about being a Merry Prankster more than actually getting anything accomplished. And I’m good with that, especially since the 17 people on Earth who will actually build this thing and hang out with it are unlikely to do much damage. (I do grant them points for creativity.)

The Pirate Box reminds me a little of AirStash, which has the advantage of being able to hide in your pocket. The notion of hidden local physical filesharing is an interesting one, and I’m sure that there are better concepts for it hiding out there somewhere. (A USB thumb drive mortared into a brick wall is just one of the gonzo notions I’ve seen recently; something like geocaching with data.) If you know of any more, send me links.

And now it’s back to bed for me.

Luck Happens: The Blotter and the Pocketwatch

Jan 23rd, 2011

by Jeff Duntemann.

A couple of people have asked me where I got the Windows blotter wallpaper discussed and shown in the photo on my January 19, 2011 entry. I stumbled across it while looking for art depicting steampunk airships. Jim Strickland and I have been tossing ideas around for a drumlin airship, and I wanted to see what other people had done in that area. Just clicking around, and alluva sudden I was looking at this. Egad, it’s 1600 X 1200 too–no need for me to do any resizing. If you’re widescreen, you might consider this one instead.

I like blotters. I had a desktop blotter at Borland that was an Ampad Efficiency Deskpad 24-003. It was basically a faux-leather frame surrounding a pad of 17″ X 22″quadrille paper, which I have always liked for sketches and off-the-cuff coding. When Borland laid us off they told me I could have it, since they were just going to dump it (and everything else in my desk) anyway. It’s followed me around ever since, though I’m not sure the quadrille paper for it is available anymore.

The only thing that bothered me about the blotter wallpaper was the pocket watch, which (while well-drawn) was just an image, and always read 3:37. (Days later, I found a version of the blotter wallpaper without the watch.) If the watch had to be there, it had to work. And then I remembered something I had seen a long time ago and forgotten.

There’s a widget engine for Windows called Rainmeter. It was mentioned on one blog or another that I followed back in 2008 or 2009. A widget engine is an app that runs without a conventional windowed UI, and allows you to display frame-less output on your desktop. The widgets are basically skins, and the output can be drawn in easily parameterized ways. There are myriad skins for Rainmeter, and while I was experimenting with it back then I ran across a clock skin called Pocketwatch. It looked a little bit Stickley (as does much else in this house) and I would still have it running had I kept Rainmeter across the last couple of Windows reinstalls. (I did not.)

On a hunch I did the obvious: I took a 6″ steel rule and measured the size of the Pocketwatch widget on the screen, then measured the static pocketwatch image on the blotter wallpaper. The face of one was precisely the same size as the face of the other. (The Pocketwatch skin is the face only; the blotter has the whole pocketwatch.) I quickly installed Rainmeter and Pocketwatch. I centered Pocketwatch over the face of the pocketwatch image, and then un-checked the Draggable setting on Pocketwatch’s context menu. Bang! The watch on my wallpaper now keeps time. All free, too. C’mon, people: What are the chances? Sometimes luck just happens.

At our most recent nerd gathering here, four of my friends and I managed to carry our 1997-vintage, 198-pound Sony CRT TV set up our precipitous stairway out to the 4Runner, and a few days later I paid Blue Star recycling $37 to see it to its final rest. Many thanks to the guys–we had been pondering how to get rid of it for the past several years. Friends are most excellent to have, especially for people like me who can’t lift 100 pounds anymore.
And this means we’re shopping for a downstairs TV. I came across a good site focused on plasma TVs, which as a class may be problematic at our current altitude of 6600 feet. Apparently they buzz and run far too hot, though the physics of the phenomenon remain obscure to me.
I’ve found the first (thin) review of the Motorola Xoom. Few details yet, but I will say up front that the cloud-based ebook system doesn’t thrill me. Early releases of Honeycomb may not support the XD card slot, but Motorola hints that an OS update will take care of that. That’s important here: Given that 16GB MicroSD cards are already down to $35, sideloading my entire ebook library would be a snap, with room left over for lots of music and videos.
I also recently found out that the Xoom GUI borrows from the quirky but interesting BumpTop, recently bought by Google and then pulled from general distribution.
I may be too old to appreciate the BumpTop 3D metaphor (I always think it looks like working inside a refrigerator box) but some good themes have been created for it, including this steampunk specimen.
Xoom has a “barometer.” Most commenters, including the LA Times , don’t seem to understand that a barometer can measure altitude with more accuracy than GPS. I doubt that the Xoom’s barometer will have anything to do with weather reports. (Else there’d be a thermometer and a hygrometer as well.)
There’s a long-running feud between Samsung and US cell carriers over who pays for Android updates, with the result that many Samsung phones are stuck at Android 2.1 and may never get an update from the vendor. (Applying the update yourself is not for the squeamish.) Yesterday afternoon, of course, Samsung denied it all. As intriguing as the Galaxy Tab looked when I played with it back in November, issues like this may keep me away from Samsung wireless products entirely.
Some images speak for themselves. Like this one. (Thanks to Pete Albrecht for the link.)
Oxytocin may be the biochemical basis for tribalism, racism, political parties, and just about everything else that the human species would be better off without. “Cuddle hormone” my ass.
Good-bye to seigniorage, not that one person in ten thousand ever knew what it was–or how to spell it.
Ahh, well. I may have eaten my last pistachio.

Displaying Wallpaper on One Monitor Only

Jan 19th, 2011

by Jeff Duntemann.

I got annoyed the other day (finally!) after being annoyed off and on since, well, almost forever. The problem was this: I was following a Web tutorial explaining how to do something in InDesign. I had InDesign up and maximized (as I always use it) and the Web tutorial in a Firefox window. Firefox wasn’t maximized, but that didn’t matter: Each time I selected a menu item in InDesign to tweak a setting, Firefox vanished under InDesign. That’s just the way Windows has always worked, and for a long time (ten years? more?) I was wondering if there were a better way. Tiling is not an option, not if I want to work on spreads in InDesign. So I just kept on keeping on, with Firefox appearing and vanishing as I ticked off steps on the tutorial.

Until this morning, when shadows on the wall told me that the light bulb had appeared over my head. Yes!

I ran downstairs and got an old monitor off the shelf. It’s a 15″ Samsung SyncMaster 570B, bought for Carol in 2003. She used it until I got her a 20″ display a couple of years ago. It has a mount pivot, and can be used in either portrait or landscape mode. I plugged it into the idle VGA video connector on my desktop, and without any fuss I had dual displays.

I’ve done that before to see how it was done, but never had the desk space for two identical (big) monitors. It wasn’t until today that I hit upon the refinement of putting the second monitor in portrait mode, which takes some space but not as much as anything in landscape mode. Now I can put a Firefox window on the secondary display while working on something full-screen on the primary display, without having to rescue the tutorial window from behind the app window each time I do something in the app window. Victory is sweet–and contains no fructose.

One peculiarity: My desktop wallpaper was partially duplicated on the second, lower-resolution display. The wallpaper image is a desktop blotter (complete with stains) and it just looked wrong having only part of it on the smaller monitor. I wanted the wallpaper on the primary display only, with just a blank color field on the secondary. Remarkably, there is no obvious way to do this. I dug around for most of an hour, trying things in both Control Panel’s Display applet and the NVidia control applet, without success. Then I hit upon this article. The gist is this:

Return the wallpaper image setting in Display | Desktop to None; that is, turn off your current wallpaper. Both screens will now have the same blank color field for background.
Select Desktop | Customize Desktop | Web. What you’re going to do is add a static image (the wallpaper of your choice) for Active Desktop, instead of a Web page.
Click New. In the New Desktop Item dialog, click Browse, and select your wallpaper image from wherever it lives. Open it. Click OK on New Desktop Item. Click OK on the Web tab. Click OK on the Display applet as a whole to close it.
The image you selected will be displayed, probably spanning both monitors. (It did on mine.) Hover over the top edge until the Active Desktop title bar pops up. Click and drag the image to whichever minotor you want to have it as wallpaper. When it’s moved completely onto one display, click the maximize button in the title bar. Bang! There’s your wallpaper, on one display only.

Now, as best I know Active Desktop was eliminated from Windows Vista, so this mechanism applies only to XP and (I presume) earlier versions. (Let me know if I’m wrong about that; I have no Vista or 7 instances here.) Active Desktop used a lot of CPU time and memory, but I think that was due to continuous refresh of the Active Desktop HTML and inane things like Pointcast that people have long forgotten. I don’t see any resource hit for having a static image in place of a Web page.

If I see any system flakiness in coming days I’ll reverse the change and let you know, but so far I haven’t seen a downside. I may try other uses of the secondary display, but I also think I may just turn it off unless I need to read a Web page while doing something else on the primary display. We’ll see.

Restoring Grub with Rescatux

Jan 17th, 2011

by Jeff Duntemann.

If a task has to be done often enough, sooner or later somebody will automate it. And so it happened with a very common task that I’m glad I didn’t have to do the hard way: Restore Grub to the MBR after a Windows reinstall overwrote it.

Windows does not play nice with Linux the way Linux plays nice with Windows. When you install Linux on a hard drive that already contains a bootable Windows partition, Linux adds the Windows instance to the Grub bootloader menu, allowing you to choose which OS to boot on startup. On the other hand, when you install Windows to a hard drive that already contains a bootable Linux partition, Windows ignores the Linux partition and puts its own bootloader link into the master boot record (MBR.) At startup, the system boots straight into Windows. Linux is still there, but you don’t get to choose to boot into it at startup.

Getting Grub back into the MBR after a Windows reinstall isn’t hideously difficult, but it’s a bit of picky terminal work done from a LiveCD. The trick is knowing how. The canonical description of how to do it is borderline incoherent, including advice like “This method apparently no longer works. Use with caution (if at all.)” The information is all there, but you have to dig a little to make sense of it. (Being a Linux geek helps a great deal.)

There’s now an easier way that I wasn’t aware of the last time I had to reinstall Windows on a dual-boot system: The Rescatux LiveCD. It’s a Debian instance with some scripting added that puts up a wizard and automatically detects installed bootable partitions. It then rebuilds the Grub bootloader menu and points the MBR back to Grub.

A couple of cautions:

The wizard is fairly terse. Don’t expect a great deal of handholding. If you don’t have any prior experience with Grub, read the documentation on the Web site. Then read it again.
Give the wizard time to work at each step. When you click the OK button, the options reappear immediately, but when there’s some disk access to be done, the script goes off to work and doesn’t give you any indication that it’s working. It doesn’t take more than a few seconds. Be patient.

I failed to be patient the first time I ran Rescatux, and clicked something once too often. (I’m still not entirely sure what.) When I booted the system again, Grub ran and Ubuntu was listed, but this time Windows was missing. There’s some rough justice in that, I guess, but I need to get into Windows just as surely as I need to get into Ubuntu. So I rebooted back into Rescatux and ran the wizard again, giving it enough time to finish each step. Another reboot, and Windows was back in the Grub bootloader menu.

Supposedly Rescatux works with both Grub 2 (the current version) and “Legacy Grub,” V0.97. My system uses Grub 2, and thus I didn’t test its dealings with older Grub versions.

It’s still a little rough, but it saved me a certain amount of eye-crossing terminal work this afternoon, and that’s always a good thing. Be careful and read the doc before you begin, but having said that, I do recommend it.
