Is the free malwarebytes OK to use? If I buy a protection, which one should it be ? I have verizon conpt service, thanks

Malwarebytes works well to identify certain programs. I use Norton

Malwarebytes is a wonderful tool for maleware. I've been using it for many years at this point. However, it must be understood, it is an incomplete solution. There is a whole array of attacks you may be vulnerable to; virus scanners and root kit scanners are still wise.
