Free Anti Spam Software

What is the best anti virus/ anti spam software to use for my laptop? it has a wireless connection built in

I already have trendmicro housecall and tried Bitdefender.
Any others that are easy to use and don’t allow, spam, pop-ups, malware…all that??
Blah blah blah…I don’t need commercials or time consuming specs. Thanks anyway.
That was for Starli…

I’ve been looking all over the place and I have tried avg and avast (are these good?), but extremely slow. I want a great free one that has no spam, spyware, or anything else like that. Thank you for all of your time and patience on commenting this.

i need anti virus software, but would like to know if i could get it for free anywhere without it being spam or a virus itself. thank you!
