I woke up this morning to a virus on my computer that blocked me from doing anything on my computer. I have had this before, where it says "You're computer is infected, buy our program now!" but it was nothing Malwarebytes' Antimalware couldnt fix. but this time it wouldn't let me do anything. It says that everything is infected when I try to run something. So I went into task manager and ended the process. It went away. For ten seconds. It kept coming back. But since i had a ten second window, I opened Hijack This while it was disabled and tried doing another scan. I restarted my computer and nothing happened. So then I went online during the ten second window and found out about Microsoft Malicious Software Removal tool. So I downloaded it and ran a scan. It said "All viruses and malicious software has been removed." So i restarted my computer. When it rebooted, nothing worked. Everything I clicked on it said access was denied. I finally found a folder I could get into, luckily I have a quick launch shortcut on my desktop. and i started rifling through folders trying to find system restore, maybe somehow get into it another way. And instead, I figured I would try to scan it with AVG, if it would open and alas, it did. So I ran a scan of my computer while it was open and it showed viruses called "Rogue.Scan" something or other. So I moved the to the vault. After that, I restarted my computer and when it booted, everything was accessible, but I had to choose which program I wanted to open it with, i.e. Open Firefox with Firefox, open System Restore with system Restore, but uTorrent opens fine, Winamp plays my movies and music, I can look at pictures, but I cant do anything besides that. It says C:\WINDOWS\system32\rundll.exe application not found. Then about 15 minutes ago, just for kicks, I looked through my task manager, and I found a program, called SVCHAST. I looked all over google and everyone says its a bad program that no one wants running. I don't want to end it, not that it messes up my computer even more than it already is, but I was wondering what I should do???
All help is apreciated
