In my opinion it is the Panda Cloud Antivirus, free version (if you want a windows product). One advantage is that it uses less resources on the PC than any other product I've tested. Another reason is that it doesn't require you to register, or even repeat that annually. With other products, if you forgot to do that you end up without protection. Then it is also completely install and forget. You don't need to continually have to update the definitions as it connect to them via the cloud, which also ensures that you are as up-to-date as possible. If you don't have an internet connection at times, it keeps a smaller local cache.

I would recommend you AVIRA free: http://www.avira.com/en/avira-free-antivirus.
It is lightweight and works good.

Just as a clarification. The "Free" version of Malwarebytes is not something to rely on for "protection/prevention" of infection.

It is a great product for helping to clean up malware, but you should be running the "Pro" version on any Windows system.

They have a special going right now at newegg.com - US$12 for a lifetime license.
Thanks for the clarification, I may have a look into the lifetime license... can't go wrong at that rate...
This is the publicly available "Promo Code" for the $12 Malwarebytes (Pro-Lifetime).
I am not compromising any license/restrictions by providing it. It is only being posted as a convenience to EE Members.
