Hello, I went away for the weekend and when I came back my husband tells me he's been getting pop ups. He was web browsing and got an initial pop up which he didn't read just clicked okay then got another one which he also clicked okay then another and another. Then it clicked in that there might be something going on so he started reading what these pop ups said. So I came home to find the computer full of trojan horses. AVG removed some, I then ran a program called combo fix. Which seems to have gotten rid of most of the rest. I do however get an alert from AVG every once in a while that I still have one called Back door.generic10.let. I've told it to fix the problem, which it does. Then the next time I restart it is there again. So I really need help finding these things and getting rid of them. I've never really had any viruses before and don't know what to do here. Thanks for any help.
