There is also AVG that is FREE! I have it on my personal computer along with superantispyware.com and it catches everything. I dont pay a dime.

I was allowed a free version of mcafee through my provider, but found it just slowed me down, and forget nortons, I found that stuff is a nuisance. it is everywhere, and slow.

I set my AVG free to scan twice a week, and it updates itself. Same for superantispyware. no muss, no fuss, no money.
