I need to put my heads together with someone. I will outline the situation: I have a new computer with Win 8 and pre-installed McAfee LifeSafe and McAfee Security Scan, as supplied by Lenovo as part of its kits. Now, after about two months, I am experiencing total dissatisfaction with the mentioned antivirus products. Constant pop-ups and annoying calls to buy something. In the last set, I had a free version of Avast (one-year renewable registration) and I was satisfied. But there is another player - AVG and there will definitely be more. I see that Avast 2015 is available, but I have no experience with it. I have no one to deal with at home, so take care of me. And then one more question, whether I should uninstall McAfee first and then install a new antivirus, or install a new antivirus and then uninstall McAfee. That is the second question. I hope I didn't bother it too much, but I won't read it in a row, it's too long. Thank you for the advice. :)
