A user reported popups that say his laptop is infected, click here to scan, etc. Ok sounds familiar.

A Hijack log shows only one suspicious file: the above named dll is always loaded at startup. I tried to remove it, but a rescan always shows it appearing again. I can't delete the file, whether in safe-mode or command prompt safe-mode. Neither Killbox nor Moveon Boot could get rid of it. Norton, Spybot S&D and Ewido don't detect it at all.

Anybody have anything else I can try, or have any info about this? A google search gave only two pages which are not in English, but seem to confirm it's malware.
The file shows no info in its properties view. The creation date puts it around the time the user started having problems.
Any help would be appreciated.
TIA!

Well the person is just going to wipe everything now. I wanted to try RKR--I think that might've showed what was recreating the file entries that made it startup. oh well, probably a randomly generated trojan name.
 
the dll actually looks like vundo!


Please download to your desktop.
· Double-click VundoFix.exe to run it.
· Click the Scan for Vundo button.
· Once it's done scanning, click the Remove Vundo button.
· You will receive a prompt asking if you want to remove the files, click YES
· Once you click yes, your desktop will go blank as it starts removing Vundo.
· When completed, it will prompt that it will shutdown your computer, click OK.
· Turn your computer back on.


Go here and downlaod the latest version of java, once
downloaded, go to add/remove and uninstall all previous versions of java
from add/remove and then instlall the latest version you just downloaded!

Hi pechenegs,
Thanks for that link--I never heard of vundo before.
I won't be able to give it a try though unfortunately, since the laptop has already been wiped but I'll save it for future reference.
Thanks again!
