I will try to explain this to the best of my knowledge. A week ago my AVG, caught a trogen horse, on my computer. which must have been hiding in my computer somewhere. The week before that, in my outlook express I got a, postmaster email saying I could not except an email cause it had a virus in it. so I deleted it. Then yesterday I get another postmaster email saying, the emails I sent could not be delivered because there was a virus in them. I never sent anyone email or attachments, which is what the post master said the email was. I keep my AVG upto date and run it daily, because of the virus problem. also before all this happened, I found something in my C drive that said mydoom, which I deleted also. Can some one please help me with this problem, I have no clue to,what I am doing to keep getting virus's and trogen horses.
