Hi guys I really need help badly and ASAP, call me paranoid but this type of thing has happened to me before and it's really pissing me off right now!
What happened was a friend of mine came to my house yesterday to copy some files from me, so I copied it for him and later that day my PC ran a lot slower than usual, like "significantly" slower. My PC is a gaming PC so it's not running slow coz it sucks or anything, it's running on i7 and 8GB ram with hd 5850 etc etc. Anyway i built it myself and i'm a pro in that part so it's not an old pc or anything. Also, i formatted my hardrive 2 days ago so it's totally clean and fresh, everything ran fine and well since 2 days ago until yesterday after i copied the files to my friend's hardrive.
Not only did it run slow, but also my PC froze after copying the files, this NEVER happened to me before, no matter how slow it could and should never slow to the point that it freezes, I was able to run Crysis & Starcraft 2 at the same time while minimizing them both to copy files or burn DVDs, basically doing tons of stuff without lag and this simple copying process to my friend's hardrive froze it just like that, it's too suspicious.
I already did an antivirus scan with Microsoft Security Essentials, Spybot Search & Destroy, Super Antivirus and Emisoft Anti-Malware and the results were all positive, no viruses found and that's pretty logical and expected since i formatted 2 days ago so i didn't install any crap or got infected.
So here's what i think, maybe it's a keylogger? This is the real problem i'm worried about, I had a keylogger on my PC be4, it logged my keystrokes and all the stuff I see on the screen, i had my bank accounts stolen and Paypal and a bunch of other IDs stolen so this is a serious problem. Keyloggers barely get detected by ANY antivirus programs, since they only record keystrokes so aren't really considered viruses.
The obviously solution is to reformat my PC again, since i only did it 2 days ago i won't lose much anyway. The problem is, if my friend's hardrive did contain a keylogger, which spread on my PC, that means it'll spread onto my other hardrives connected to the same PC right? Will it also spread over my wifi network?? I did a lot of Google search and 25% of viruses are easily spread on USBs, and that there's a possibility that they can also spread on a wifi home network. So if my parents or siblings use wifi as well, the virus will spread to their computers too through the router then?? My router is pretty good but i don't think it has firewall, i checked the router homepage and it doesn't seem to have it so i'm worried whether viruses now days can actually do that.
I also tried a system restore and that didn't even work, it just hangs in the system restore screen that kept showing "restoring registry files" or something like that for over 30 mins, it shouldn't take this long and i never had it like this long, especially that my PC is fresh after being formatted.
BTW, I've learned my lesson now and have gotten several good programs that disables autorun.inf on USB as well as USB scanning programs with several other features. But I really need some advice on what to do, obviously i can simply reformat all the computers in my house but that would mean losing all the files on them. But if i backup those files, i obviously need to connect a USB to the PCs, which would then get infected as well. I'm not sure if i can burn the files to DVD, whether the viruses will somehow silently get burned to the disc without me knowing.....
Sorry for this super long message and please don't think i'm paranoid. When you've been keylogged before and lost over $1000 because someone had your bank account details, you can't help but feel helpless and frustrated in a situation like this. Now i can't even trust anyone with their USBs to copy files from me.
