Take a gander at this from a customer's machine.

File is called LISTING.TXT.
Now I've seen this virus before, but only ONCE before have I seen it so rampant. I've seen it duplicate itself like 10,000 times in the root of a few partitions on another persons machine. This one though is the second one I've seen so bad. Approx 2000 on each partition, bringing the total to 6000+. To clean this, the fastest way I've found is to hook up the drive to my machine via USB enclosure or attachment, and then scan using my AV. After cleaning, I put back - install some free AV - then run a full scan. Usually it's ok after that, but today I got an interesting surprise on another machine.
Setting up a PC for my niece, fresh install of XP. Regular stuff like Office and AVG and CCCP and SP3. Then I noticed that ever so often, while there was an internet connection, I kept on seeing AVG pop up say it find some EXE file which is infected in the SYSTEM VOLUME INFORMATION or in some other system folder or temp folder. Them viruses feisty - coming in on the back doors of Windows and getting the PCs. And this is with NO BROWSING being done. So now if a customer machine infested, I know it's because they have no good AV app or were just unfortunate, and not necessarily my first impression of them being stupid and clicking those pretty pop-ups about "your system is infected, click here to remove" - maybe they're not all that silly.
