Hello, I am using the free version of the AVG Anti-Virus. And I have a question about it. I hear that it's gotta be the best free anti-virus program, but I am having trouble getting it to detect viruses. I do not see how my computer could be virus free, but AVG never detects any virused. I run Ad-Aware and 2 spyware programs, both which are free(only one finds viruses....), and I appear to be clean. But, everytime I e-mail my friend, he's always saying how I'm sending him viruses. I am curious to know, is it possible that I'm so infected, that not even my protection agents are working? Or am I missing something? Thanks in advance.
