No anti virus on linux systems needed

But my Qnap NAS has an internal scanner and on my side-by-side Windows 7 Installation I prefer Kaspersky Internet Security.

love eset

Im using 360 for more than a Year and its really good . It has many interactive features like Sand Box and has a free firewall as well.

I used AVG for years, switched to ESET for a bit and will soon be trying out Avira. I've yet to find my perfect fit.

I have used many different free antivirus, and prefer Avast.

Eset has gotten even better since this pole was created. Using Eset smartsecurity now. tnod makes it pretty easy. Have run avast, mcaffe, norton and kaspersky in the past. Just wish eset had a full sandbox.. but there are programs for that.

Avast is quite good in my opinion, and very light.

Kaspersky all the way

Windows defender

AVG I think, personally I don't use any virus protection, just be careful what to download.
