It started with just a fake "live security" so I did rkill and malwarebytes, thought that did the trick. after rebooting, suddenly was getting an error message WINDOWS HAS ENCOUNTERED A CRITICAL PROBLEM AND WILL RESTART AUTOMATICALLY IN ONE MINUTE. PLEASE SAVE YOUR WORK NOW. At the same time, MSE pops up an error and if you click "Show Details" it mentions something about this Trojan Sirefef thing and services.exe (731) or something. Can't read too much before it auto reboots. Please advise.
