I was infected by two viruses at once when i was downloading desktop wall paper. My Microsoft Security Essentials picked up: Trojan:Win32/FakeCog & Backdoor:Win32/Nuwar.A These viruses on top of pop ups, blocked me from using Internet Explorer and whenever i went to my firewall page to see if i could turn it on, a fake window appeared. Somehow, after numerous failed attempts Microsoft Security Essentials was able to get rid of them, but I'm still left with a potential new one: Trojan:Win32/Vundo.ME

There are no more pop ups and I've used my Microsoft Security Essentials several times to see if there were any more viruses but it does not detect anymore. I've gained my firewall window back and everything seems to be working fine, except my Internet Explorer. I use Firefox, but when i opened Internet Explorer it wouldn't work. It just displays as if i were not connected to the internet.

I'm trying to download Spybot S&D but when i go to install it says it can't connect to server.

I'm running windows 7 64bit.
