Hello! I've been having problems with my computer for a while now. I use Windows 7 Ultimate Edition. I've tried scanning with Malwarebytes, Spybot, and Avast! Free Antivirus, but those freeze up at some point and can't be completed. I've done scans with Roguekiller, adwcleaner, TDSSKiller, and Rkill, all of which take longer than they used to before I supposedly became infected, some longer than others. However, after they're done, they don't show anything seriously wrong, except with the Rkill log which says:
"* Cannot edit the HOSTS file.
* Permissions Fixed. Administrators can now edit the HOSTS file."
But upon running again, it keeps giving this same message. When I use the immunize feature in Spybot and run Rkill after, it says the same thing but also lists a few of about 15,000 HOSTS files that have domain names that are obviously fishy, with some that have names that suggest pornography. Some of these HOSTS files are: 127.0.0.1 www.007guard.com, 127.0.0.1 007guard.com, 127.0.0.1 www.0scan.com, 127.0.0.1 1000gratisproben.com, 127.0.0.1 032439.com, 127.0.0.1 100sexlinks.com, 127.0.0.1 100888290cs.com, 127.0.0.1 www.1001namen.com, among others.
I've noticed since I've had these problems, my computer has significantly dropped in performance and freezes up programs constantly. There is also a csrss.exe running without description or file location, though I don't know if that is relevant to the main issue at hand.
All these problems stay constant in Safe Mode as well. It probably wasn't such a good idea running these things on my own, but it can't be helped now that it's been done... I'm not sure what to do as scans don't show really show anything or can't even complete scans that can quarantine malware, so some extra help would be greatly appreciated before I completely give up and get a new hard drive or something.
