I keep getting Trojan Viruses?

and when I scan my computer with my antivirus it says it deleted them but my computer is still running super slow. I ran the spyware and nothing is helping. Normally when I get this problem I just restore my computer back to original settings, but I cant do that this time because i have some stuff on my computer that i can't lose until at least christmas. And if i restore i lose everything. Anyone know what i can do. And somehow every bogus website got my main email adress and now everytime i open email i have a thousands messages, most are viruses. How can I see who the message is from without actually opening the message. my primary email automatically marks as read when inbox or spam folder is opened. I really need some help.

Get the Spy Sweeper by Webroot. I have it on my comnputer and it is awesome for getting rid of trojans. Sometimes it may take a day or a week at the very most but it will get rid of them. If you install it, run it everytime you turn on your computer.
