I'd never heard of it before and was using AVG but had a few probs with it. This was recommended in a copy of Micro Mart a few months back and I can't fault it at all.
Tis free too which is a bonus

Same here, Avast is good. The updates are automatic, its easier to use than AVG and uses less memory. The big AV commercial enterprises could learn from this app.
Mind you, use a decent spyware/adware program as well. I paid for Webroot spy sweeper and my machine has been clean and running like a dream ever since.
