Today, I tried turning on my computer, only to find that I was facing a black screen with a mouse icon and nothing more. I was unable to open the control panel by using Ctrl+Alt+Del, so I promptly flipped out and reset a few times to see if the problem would persist. It did.
After a bit, I restarted in safe mode, and was able to do so successfully. I then returned to a restore point that had been set only a few days ago, and I'm lucky for that. I had hoped it was just a corrupted boot file, but when I tried to run a scan through BitDefender 2012 just to be safe, I noticed something peculiar. For one, it acted strangely at first, getting disconnected from BitDefender's servers the moment after launch. I restarted and this time BitDefender stayed connected. When I ran the scan, I took a peek around to make sure everything was on the up-and-up. It wasn't.
The Firewall had been turned off in the settings menu and the AntiVirus settings were all set to minimum and a 'custom' setting for On-Access that made it so BitDefender wouldn't check archives or the boot sector. I set these back on and waited to see how soon the virus I obviously had would set them back. Thus far, I can only say that it sets the Anti-Virus to these 'custom' settings whenever I start a scan. I'm assuming its doing to preserve an infected archive somewhere. I don't know how to do a proper scan and delete if my trusty antivirus software has been compromised.
This virus is obviously using my own administrator permissions to do this. Is there a way I can prevent it from doing so? How can I do a manual scan on the archives and boot_s sector of my computer and get the bugger?
