This Security Shield bullcrap keeps popping up on my computer, every freaking two minutes! It doesnt let me open up files, it tells me that my computer is unprotected and from my research, this thing is an infection and needs some sort of antispyware thing. I tried downloading something from malwarebytes and something else from PC tools but the security shield thing wont let me access it. Please please help, Im going insane! :'(
