Spyware: www.lavasoft.com search for their free version of ad-aware. If it’s not from lavasoft it’s not the real thing.
Anti-virus: free.grisoft.com and download the free version of AVG. So good I’ve many times thought about actually buying their commercial version.
I went to lavasoft and clicked on the free home version. It wasn’t, I’ll go back and see what I missed concerning the free part.
