Ive been infected by something calling itself antivirus.net. It stays in my tray and gives annoying popups saying Im infected with a virus and need to register with them to get cleaned up. Ive downloaded malwarebytes but it wont run as antivrus.net is stopping it. Also I cant use task manager as it turns it off. System restore wont work either Could anyone advise on how I should proceed please (please no wild guesses, I need expert help). I have no knowledge of dealing with these things so please be patient with me.
