Just got a virus, so I figured it's about time I got rid of AVG >.> Can anyone recommend a a half decent free antivirus that wont spam my screen with adverts, and wont require me to run a separate firewall etc? Mainly, I just want it to sit there, and shut up, which is why I've been using AVG up till now, but it fianlly seems to be becoming ineffective, as I had been warned.
