Hello friends I got mcafee antivirus free with my laptop and installed it 3 months ago.it the worst antivirus I have ever used. It just slows down the computer. If u install any game amd run it just deletes the game file without informing u. Today after I updated the antivirus it aksed to restart the computer I restarted and screen goes black. After sometime it returned to its original position but after the pc is lagging too much. Where it comes to security it always show safe but still pc lags.for internet user and gamers its the worst antivirus. I have uninstalled it and baught new even though I have registration of nearly 1 year left
