I have an HP Pavilion DV6. Several days ago, it started running extremely slowly. I went back and it looks like McAfee did an update and that's when it started. I took McAfee off (am going to install AVG) and now the computer is very fast. But I have no network connections. When I try to connect the Wi Fi, the computer says it's connected to 'no name provided'. I ran Malwarebytes and Hitman Pro and only found one piece of malware. Please help!
