There are loads of Antivirus's out there, i use COMODO as it's quite good and it also comes inbuilt with home protection/antivirus/firewall and it also comes with a premium license to, all free
There's no such thing as "best free antivirus" - when it comes to viruses, the problem is usually between the keyboard and the chair. Speaking for myself, I've been using Avira for quite a while now, I had a one-year license back in 2007-2008, then I continued using the free release. No special issues with it, but it's not perfect, either. I also used AVG Free and a few others and one thing's certain: if all tests say one antivirus is the best one today, it doesn't mean tomorrow will be the same.
yeah.. nod32 is good. I've tried it. but now I tried KAV 11.256. it's good antivirus. but just trial in 30day, and if we have low ram. it's very slow with my PC. but I think good antivirus
Avast free edition would do your work. I am using it Avast free edition from last 2 years no problem yet. AVG slows your PC....Go for Avast Antivirus (free edition) in my opinion....
I think AVG & AVAST both of them are best. You can get it for free edition from http://www.filehippo.com/download_avg_antivirus_32/
Avira Antivirus is the best, it has also firewall to save your PC from malwares, and other online viruses.
Every one hates getting bugs, so awhile back I made a quick o site at Wix and pointed Bug Genius (dot) com at it. Free antivirus downloads. Microsoft / Mac. Free Mal-ware tools also. Resources links complied together. Nothing fancy here, just useful.
