A friend of mine has noticed that his computer was infected with a Trojan Horse.
He told me he has AVG 7.0, a trend micro internet security (I don't know what that is) and AD-aware 6.0. He informed me that none of them are being able to delete the virus, because although AVG does clean it, it reappears in a couple of days. He also told me that he isn't succeeding to update AVG and the trend.
What could he do to get rid of the Trojan Horse?
