I was on the internet, I clicked on a link when all of a sudden my screen freezes. Afterwards my wallpaper turns black and says “microsoft security center had detected spyware/adware infection! It is fervently recommended that you use special antispyware tools to prevent data loss.”
I can’t exchange the wallpaper, but besides that everything else seems normal.
