Remove Viruses/Trojans

Hello, I am having problems with my desktop. I do believe there is trojans infected on it. I have AVG and Trojan Remover at home, the AVG does not seem to be removing or quartainning the virus or viruses and the Trojan Remover that I have seems to be expired,(was only good for 30 days, for free).

What can I do to remove these from my desktop without taking it in to get repaired and costing me an arm and a leg. I have been searching, but not sure what will work or cause more problems for me.

If anyone can help me please write back.....when I run the Trojan Remover the names do come up, will it help if I post the virus names???


Also how can I speed up my PC, I have already removed unused items??? Very slow, how to speed up pc?


Please awaiting help
