I saw on the other thread that people use Avast. I have never heard of it. I just looked it up, it's free.
Why do you like it? Better for you than Norton or McAfee?
I have free McAfee. It is THE most annoying software. You can't set the day and time to run scans and updates, it does it when it feels like it.
I'd love to get rid of it, so speak your minds.
