I've gone through several searches this far. It began before I had AVG antivirus, so I downloaded it thinking it was a malware/virus issue and it wasn't, so I uninstalled and completely removed AVG. Every download, regardless of source, on IE is marked as virus and deleted. I had IE 10 and downgraded back to IE 9. I even reset IE per instructions. Not only that, but Microsoft Security Essentials, at the same time, stopped working, saying I didn't have administrative access to enter it and it couldn't open the source. I'm on the Admin account! We have no other user accounts. So, HELP! I'm completely at a loss.
