Avast for it's gaming mode with free version. And as for not trusting free ones, some of them perform better than paid for so what's not to trust?
Thankfully the price of a program rarely reflects how good it is and to be honest its the top paid (Norton and Mcafee) ones you would want to avoid not the top free ones Avast and Microsoft security essentials best free ones IMHO. I have used avast for the past few years on all 4 computers I own, never had a problem. You should also scan your computer now and then with the free Malwarebites to remove any malware But as someone already said the best method of avoiding viruses is common sense.
common sense isn't as common as it should be, if you are constantly hit by malware, maybe get the paid for version of malwarebytes, as it is designed to run in conjunction with your chosen av package, and blocks most of the malicious websites from installing anything. I put it on the wife's machine when she was getting malware from infected Facebook ads, she hasn't had a problem since
Norton and BitDefender are some of the best paid solutions but there is a lot of good free antivirus software. Some of them are MSE, Avast, AVG, Avira.
Norton and bitdefender would need to pay me to use their products. They are awful, all your need is MSE and common sense Sent from my GT-I9300 using Tapatalk 2
