Bargain Buddy is getting nastier
I don't know how long this variant has been out there, but I got hit by bargain Buddy this evening and neither AdAware 6 nor SpyBot 1.3 could clean up my machine. The stupid thing just kept coming back (even with hand editing of the registry). It turns out that it had installed a service (I'm running Win2k, but this exploit would work for WinXP and WinNT), and the service was re-polluting my computer with various files each time I restart (it wasn't content to have just one attack vector).
So if you're having a problem getting rid of it, look for a service (Start / Run / services.msc) called ISEXEng and disable it. Then look for a file in c:\WINNT\system32 called "angelex.exe" and delete it. I also found the following files in that folder which I believe are additional vectors for infection:
exdl0.exe
exdl1.exe
exul1.exe
javexulm.vxd
mac80ex.idf
mqexdlm.srg
netut80ex.vxd
vx0.nls
vx1.nls
vx1x.nls
These later files are probably baddies. Their removal hasn't caused me a problem yet, but I found/removed them only because of their creation date (today), and the fact that many of then had a last modified date older than their creation date.
I'd really like to take big stick to the cretins that write/release these things...
