Greetings,

Roughly a week ago, my wife had a run-in with "MS Antivirus" while doing some shopping on-line. Not being particularly computer savvy -- even less savvy than me, and that's saying something -- she mistook the faked warning page for real, and proceeded to download some associated malware. (She didn't purchase anything, but there was still an associated ".exe" (which I'm pretty sure she didn't run) on the desktop when I got home from work to check things out. She was running Firefox when she encountered this junk. Maybe that helped minimize the effects...) I wasn't present when this happened; details are fuzzy.

That same evening, I deleted the executable that was left on the desktop, and proceeded to update and run a full MBAM scan, which turned up no apparent issues. I felt OK about it, and shut off the computer for the evening.

The next day, the AVG 8.0 resident was complaining about something related to this "MS Antivirus" malware. (I've since forgotten exactly what it said.) I ran a full AVG 8.0 scan, and allowed it to remove five executables that it referred to as "Trojan horse Crypt.BQI". These executables were scattered about in "Documents and Settings" and "System Volume Information". (I think I can find the log if it turns out to be important.)

Since then, I've looked through the Add/Remove Programs listing and run scans with the Windows malicious software removal tool, AVG 8.0, MBAM, and ESET, none of which have shown anything that I can see as terribly bad or that appears to be associated with "MS Antivirus".

Perhaps I'm being overly anal-retentive about this, but the updated MBAM scan not finding anything the day of the malicious download threw me for a loop. I'm hoping that someone far more knowledgeable than me can look at the logs below and tell me if I'm missing anything obvious, or if there are any other actions I should take that would make me feel safer about using banking websites and the like once again from this computer.

Thanks,
Pete

Don't see anything suspicious in the logs. Is the computer running all right?
Judy

Judy,

Yes, the computer seems to be running as well as it ever does (which is slow, but that is explained by the horrible lack of adequate RAM in my machine...)

I just wanted somebody knowledgeable to take a quick look at the HJT logs and tell me what you told me -- that you don't see anything suspicious. Even if details of the incident weren't fuzzy, I'm sure I wouldn't know what to look for.

Anyway, thanks a lot for your time and help.

Pete
