I am a stupid when it comes to pc's. I bought a anti-virus...software, that was from the university I went to. And after that and a checking for viruses, I could no longer use ie or QQ messenger. I got rid of them and downloaded them again, restarted my pc thousands times, but nothing is working. I keep getting a message that something needs to be done with my fire wall and HTTP, HTTPS, and FTP ports.
