I need some serious help. something similar happened to me but the virus hit me pretty hard. i was simply browsing the nexus when this ad virus came up for a security check and before i could do anything it tore up my computer. the wallpaper turned black, any shortcuts for games on my desktop disappeared, and now everytime i play a game on my computer all the letters on the keyboards are mapped to a random number (i.e. i try to type 'w' and a '1' pops, etc.) and i even tried making a new user on my computer and the virus still carried over to that. and no one in my family has been able to fix (we're pretty big computer nerds) so i was wondering if you guys had any suggestions?
