best free antivirus softwareWhat is the best free antivirus software?

I'm running Windows 7 and my free three months of Kaspersky is about to run out. I would renew it, but I'm a little broke right now. So, until I can spare the money for it, what's the best free antivirus software?
I recommend AVG along with malwarebytes. They work well together and are free. Both of them have premium editions that are a little better. You can purchase it pretty cheap if you go through someone who gets them bulk.
The best free antivirus is Microsoft Security Essentials from microsoft. The source is :http://ajayshah2005.hubpages.com/hub/Microsoft-Security-Essentials-Best-Free-Antivirus

If you want free then I recommend Avast , superantispyware and Malwarebytes. coupled with Comodo firewall They are all frbest free antivirus softwareee for personal use . It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. You should run A/V and anti spy weekly.
Avast! Antivirus is actually better than AVG, Norton, Kaspersky. I find it works just as well as any other antivirus and it takes up less memory while. running. It's also free forever. I highly recommend you just use Avast.
just pirate Norton Internet Security from thepiratebay.org . My cousin had "Avast" and it made his computer LAGGY! Norton works quietly in the background and is the leader in the market.
