Best antivirus windows 7

its a matter of personal choice. i use Microsoft Security Essentials because it is lightweight, unobtruisive and FREE!

Check this guide out:

Avast, Avira, and Microsoft Security Essentials seem to be the most popular here at THF. Personally, I use and recommend Panda Cloud Antivirus. (For ongoing protection, that is. Malware removal, once you're already infected, is another story...)

I second Microsoft Security Essentials. Works for me and free.

+1 for Microsoft Security Essentials. Only complaint I have is that the name takes too long to type....

I'm liking MSE used with Malwarebytes for back-up.

Hi sitham - It seems to be a personal preference, but it Microsoft Security Essentials is a great place to start. It is always free, so there is no risk to trying it out! http://www.microsoft.com/Security_Essentials/

@ Herr_Koos - Ha ha, You can always type MSE!

I would, only then OP wouldn't know what I'm talking about. Invent a shorter name, please!  

Microsoft Security Essentials is great. Just make sure it doesn't run on startup

Why? Mine runs on startup with no issues whatsoever.

Yep i also have my MSE run at start-up.

Microsoft Security Essentials is the best right now.
Its better then avast, avg, eset, norton and so on.
Its free and its best  

Honestly, I don't use any. I don't get viruses until someone else starts using my computer. The internet, like many other things, just requires good judgement. If you aren't downloading torrents, shady programs, or other *stuff*, you should be fine without.

^not a good idea

you can get viruses just by visiting a website

Though safe commuting is always a good idea, no one is completely safe of viruses. As jefe323 said, you can pick up a virus by simply visiting a website (even if you think it's safe). Why not just download Microsoft Security Essential for free (it's 100% free) to make your computer more secure?
