Posted 02 February 2009 - 11:55 AM

So I misclicked an ad window last night and hit a .pdf archive that installed all kinds of joy onto my machine. I've since used Hijack This and Combofix to purge the malware (turned off system restore, ran it all through, etc, etc), and everything seems normal. AVG picked up the downloaders well before I ran Combofix, and all functionality is restored (automatic update functions again, no idiotic windows popping up every minute or so, etc). However, all said and done I'm now a bit paranoid. Can I get a second opinion on this logfile while I make my tinfoil hat and such?


Thanks a ton for your site, btw. Saved my grad school homework and my contract work. Do you accept donations, of either cash or alcohol? :thumbup2:

I've also attached the combofix log file. Malware/antivirus/etc. has found nothing but I'm still paranoid.

Hi,

I don't see anything suspicious in your logs. I see Combofix already deleted the malware and the rest of the Combofix log shows clean as well.

Thanks for the assistance.

I did have a brief resurgence which my antivirus and Malwarebytes picked up and removed reasonably quickly. However I'd rather not have to keep watching for this perpetually.

The new infection seemed to be located in the windows restore point files (apparently I didn't disable that quickly enough). I remember seeing a way to 'clean' that and start from scratch, but I can't seem to find it now. I've attached the malwarebytes log showing the file infections.

Will I need to purge this restore file or should I be ok now?

Hi,

It's totally normal that Malwarebytes finds those. As you see, they are located in the Combofix quarantine folder (Qoobox) and System Restore points.

* Go to start > run and copy and paste next command in the field:

ComboFix /u

Make sure there's a space between Combofix and /
Then hit enter.

This will uninstall Combofix, delete its related folders and files, reset your clock settings, hide file extensions, hide the system/hidden files and resets System Restore again.
