I was on YT earlier when Firefox completely shut down and this Windows 7 security thing came on and wanted me to purchase some malware something or other. It said a bunch of stuff like Trojan this and that plus Malware. Nothing on my computer would open and it installed a keylogger on my computer so it was being watched. Hubby shut off my Wi-Fi and I did a system restore to the last update I had a few days ago and it seemed to take care of the problem. I wonder what's going on...
