Re: clash of the giants.
If you want the best and you plan on paying for antivirus, go with Eset Smart Security. By far the best protection suite that I've tried (I've tested many of the popular name brands). It has better performance than Norton, McAfee, Kaspersky, TrendMicro, Webroot, etc. But, if you wanna stick to free stuff, go with AVG for real-time protection and Malwarebytes as a secondary scanner. I actually recommend the free products to people who just browse the web and check emails and stuff.....but if your a heavy internet user and downloads things frequently, I recommend to get a better software suite than the freebies.
