PC
Win7sp1 (genuine)
using MSE (with realtime)
Crome browser
(not sure what might be relevant, will post DDS soon, read below)
What Happened:
went out to dinner (aprox 2 hrs), computer was left on. utorrent was installed but (iirc) not running. (has now been uninstalled/deleted, wont be coming back!). Came home from dinner and found my PC was blaring out adverts (audio only) and microsoft security essentials (MSE) had found a couple of threats, the
Pearls.D!plock
and a backdoor trojan
Backdoor:Win64/Bedep.A
which had been quarantined.
Utorrent was running, as i mentioned i dont think I had left it running, I haven't used it in months.
adds continued even after quitting utorrent and crome.
searching online, i found a few forums with recommendations of TDSSkiller and AdwCleaner
TDSSkiller found nothing.
AdwCleaner was successful in finding some suspicious files, which also killed the adds.
after opening a few more forums (like this one) on the subject i disconnected the infected PC from the internet.
I've since ran a few more scans with MSE and Adwcleaner, a full scan on MSE found
JS/obfuscator.fn
which was successfully quarantined.
Adwcleaner on a subsequent scan (after restart, and after cleaning of Obfuscator) found another dodgy 'web browser' in crome\user data\default\webdata [search provider] which was also successfully cleaned
subsequent scans from both come up clear
What Now?
I haven't run a DDS log yet... I wanted to check first if these torrents are likely to spread to other pc's on my home network, or may have already? the infected PC user did have write privileges on other network PC's. is there anything to watch out for before allowing the infected PC back online to get DDS software? I'll turn off all other PC's and download DDS stuff in a day or so unless you guys advise otherwise...
Do you guys know any more on the parls.D? I couln't find much on this trojan other than it allows lots of bad stuff like remote logins and sending of security info, hence quarantining the PC from the internet as soon as possible.
anything else you guys can recommend is much appreciated. Once again apologies if i've messed something up.
thanks.
edit
ultimately i can re-install my OS if need be, important stuff had been backed up recently. Prefer not to if possible, and also would like advice on other network PC's. I'm not bad with pC's but no pro, as you can probably guess form this post. cheers.
