I have removed 80 Trojan Horses this past weekend. Downloaded MagicIso while I was intoxicated and didnt do my normal procedure of Virus Scanning anything that has been downloaded before opened. I didn't do it and this time I'm paying for it. After removing these 80 Trojans, most are gone, but the computer is running very weird, so I know there's some on there still. I used AVG and Avast, they've helped but not enough. My computer is running very sluggish, pop-ups, and I cannot access certain websites. Such as this forum. I'm at work, so I finally seek assistance. I could easily junk the HD, but I will be left stuck thinking about "How could I have fixed it" and I rather fix it then junk it. Also, the virus disabled many of my abilities such as "Display", Task Manager, and other things. Also, my C drive isn't showing, only E:. It's there, but it's not showing. When I go to the Start menu, the All Programs section is gone. Many things pop up with messages saying it's been disabled by my System Administrator. How do I change it back?

Please help, thanks a lot.
