Ok if you don't have a windows disk then just do Factory Recovery. To do this shutdown your computer then turn it back on right when it is starting back up hit F2 i think. Depends on your computer it takes you to a menu. And there will be a option Full Factory Recovery hit enter on it and it will do its thing and restart. And your computer will be like when you bought it. EVERYTHING YOU HAVE DOWNLOADED PROGRAMS, MEDIA ECT. Will be deleted also. Like new.
No, I dont mean viruses you get from sexy time. I mean virus sexy time. Viruses having sex, ie, shuffling round their genetic material.
HIV-1 sexy time Ive written about before-- because HIV-1 is diploid, two copies of the genome are packaged into one virus. There is lots of 'hopping' during reverse transcription, so sometimes things dont 'hop' perfectly, and the resulting virus is different from both of its 'parents'. Thats how HIV-1 gets a shitload of its diversity (NOT just error-prone reverse transcription).
