Well, you are half right, and half wrong. Repack is not fully virus, it is half pirated and half licensed. Repacks are fortune viruses, which should not to be confused with CASINO virus. The repacks are kinda useful, as they are half pirated and half licensed. Pirated editions are the most dangerous programs, Repacks are half dangerous and half safe, and Licensed editions are safe, but can have a cost, which might bother to play/use the licensed games/programs. As i said, repacks nerf the cost, but are fortune viruses, not the ordinary viruses!
I have downloaded a rouge anti-virus called SunsetSecurity, it keeps making these fake MS error messages saying i have 1 Trillion viruses and that i should download BonziBUDDY because he can 'fix' things, have you heard of this and how do i remove it
