I'm using AVG too, But when I was using other anti-virus I was infected by
Trojan.Lodear - it makes my browsers very slow and if I enter a wrong domain or url it directed to another sites which are porn sites. I recommend you use AVG because I using it and no more viruses can be found in my computer. But make sure you keeping up to date with updates and installing them immediately! or else you will be in trouble.
