Hi! I really need some help... My computer has got infected with sirefef almost two months ago and now I cant use it at all. I´ve been googling trying to find a way to remove it but I wont make it on my own. Every time I start it a warning pops up : "windows will shut down in a few minutes, please close all programs" and then it shuts down before I can do anything. I got a cuple of AV programs but none able to remove it and now I cant update or anything... Would very much appreciate som help!
