I've only ever used free ones because it just didn't make sense to pay for an antivirus, at least yet. I exercise caution by not clicking anything and everything I find on the net. So far I've had good experience with Bit Defender (nil resource impact on my 5 year old laptop running Win 8) and Malwarebytes Free.
I tried Malwarebytes' one month premium trial and must say that it makes more sense to get the paid version of Malwarebytes because it scans for malware in real time which can be serious if not detected in time. If a big virus is going to hit my computer then I really doubt if any of the paid antivirus is going to save me. For the other ones even free AV should suffice.
However, I've just joined this forum to get help with my first pc build so I will definitely buy Malwarebytes but will continue to run Bit Defender free.
