I am currently searching for the best anti-virus that is does not make my pc slow, also that scans more viruses.

I use the Avast! free version, it stops a webpage loading if it suspects malware, I'm happy w/ it.
I use the Malwarebytes (free also) for my PC/Dl scans but don't have it running in the background.

I too use Avast free home edition and am very pleased with it
