I'm running Windows XP Professional SP2 with AVG 8.5 as my antivirus. A few weeks ago, I had some pop-ups, random audio ads with no visible windows, and a weird process showing up in Task Manager (svchasts.exe). Then AVG said my E-Mail Scanner wasn't running. Then it stopped updating, then it stopped scanning on schedule. I reported the problem to AVG; they sent me a repair installation that I was able to run and it found and healed a couple of viruses, but there was one that it found and couldn't get rid of: a trojan named Cryptor.
So I searched for help on Cryptor (that's how I found you guys
) and I got some info about MBAM and SUPERAntiSpyware. However I couldn't install or run either program (even after renaming). I was able to get a bit of a reprieve when I downloaded and ran the Sophos anti-rootkit; it got rid of the pop-ups and ads, but I was still running slow and some of my links were being intercepted by Google searches, i.e. if I opened nfl.com, I'd end up with a Google search for nfl.com.
Last weekend, I booted up and was unable to start IE or Firefox; said I couldn't connect to the server. Funny thing is that both my modem and router are showing a full connection to the web (I can still browse on my PS3). In addition, None of my peripherals are recognized: the computer says I have no printers installed, it says I have no access to the Network Connections folder, it says I have no scanner installed, it says I have no CD/DVD drives installed. When I try to move files from one folder to another folder or drive via cut/copy/paste, the Paste and Paste Shortcut options are grayed out.
I have no idea what to do (I'm sure I've already done some damage in my desperation). I would truly appreciate any help you all can offer. Thanks.
