Looking for a good free/free version of a Anti-Virus

[Decepticon]

Recently, I've been trying to look for this one McAfee anti-virus disc for my laptop, but while I can't find it, my Malwarebytes free trial went out, so now i'm trying to look for a free/free version of a anti-virus to fill in temporarily.
Ones i'm trying to decide on getting:
Khaspersky (Atleast, I think that's how it's spelled)
Avast!
Microsoft Security Essentials
or
AVG.
Also, I can only choose one of these, considering i don't want two anti-viruses scanning and doing all it's stuff at the same time and interfering with eachother, also adding a poll.

I'd recommend AVG, it has protected me in the past, and still is today.

bump, in need of more votes.

Avast. Do not, I repeat, DO NOT get AVG.

A lot of people have been in need of new antivirus programs lately.
Use Avast.

Avast. Do not, I repeat, DO NOT get AVG.

This may be an idiotic question but, what's wrong with AVG?

Avast has blocked viruses pretty well when browsing beasiality sites, I recommand it to amybody who does the same.
