systemsecurityvictim

Hey malwarebytes, im infected with the System Security rogue p.o.s on my pc upstairs (it uses wireless, i'm on the one with the actual modem) I tried to download mbam to get rid of it, but system security won't let me open any programs. i tried to boot in safe mode but my monitor does not turn on until i get to the "log in" screen, so i guess i really can't. Apparently i got it while i was away from the computer, i came back and it was there. i can't open the ctrl+alt+delete screen, either.
