  Those looking for a free A/V solution should check out Avira,
  though you'll have to disable the annoying upgrade popup.

Yes! I was going to ask if anyone used it, and what did they think of it, because there's been a long time since I don't work on a windows machine on a daily basis, but at the time I did I used Avira.

I was just wondering if after the years that passed it had become less good or something...

Switched to Avira for almost a year now for most of the machines at home and friends. No problems so far, and works fine.

Still, the nag screen is annoying, but how hard it is to click one button. :P
