As alreayd mentioned - don't run two anti-virus software packages simultaneously.

Also, already mentioned - no system is secure.

Assuming you don't want to get virus from casually visiting websites or checking email - you are off to a great start.

Unfortunately, there is always someone trying to write spyware/virus/trojans/etc to get around the latest security measures and there's always a chance you can get that virus if your security software does not have an update for it.

Mostly, just being cautious about where you go and what you install on your computer will keep you safe, especially in conjuntion with the security software you have.
