Greetings -- I have worked with this site once before to resolve a tricky issue -- I appreciate everything you all do!

My uncle's laptop has been infected with what Norton AV is reporting as "Hacktool.Rootkit" and "Infostealer". I've gotten the machine as clean as I can with a combination of MS Antispyware, NAV 2003, Ad-Aware, and Spybot S&D, all with current definitions. The machine is running Win XP Home, and has all the updates from MS Update. I've also already run ATF-Cleaner.

When I reboot, the firewall gets shut down and the Security Center Service gets disabled.

Hacktool.Rootkit gets detected by NAV, linked to c:\windows\hide_evr2.sys. The file gets deleted, but of course finds its way back. Infostealer gets detected, linked to us_biz_plusik[1].exe. Same deal -- gets deleted, comes back. The same time that Infostealer gets detected, an .exe with a 7-random-digit filename also tries to run, but blows up.

I've downloaded and run RootkitRevealer, but I'm still learning how to interpret the results. If the output from that would be helpful, I'll be glad to supply it.

I'll attach my HJT log below. If there's anything you can do to help me resolve this issue, it will be much appreciated!

Thanks so much,

Matt Smith

** UPDATE **

After my initial posting, my RootkitRevealer scan finished, with some files listed at the bottom of the results as follows:

I've deleted all those files, plus everything else in any folders under ...\Temporary Internet Files\Content.IE5. After a reboot things seem pretty stable at this point. If there's more anyone still believes I should do, please don't hesitate to speak up!

Thanks,

Matt
