Can todays threat be prevented?

today the biggest threat faced by computer users is crimeware. now what is a crimeware? A crimeware is a malicious software that is written by cybercriminals like me before, i used to write crimewares. but not to steal money. just to steal passwords from my girlfriend, i mean girlfriends coz there are many of them.
this allows me to see their Social sites accounts like friendster,myspace and facebook. just to see whether they are loyal or not. coz this is important to me. and thank god i have caught a bunch of them cheating.. anyway lets get back to crimeware, a crimeware is written by cyber criminals with the sole purpose of making money illegally.

Crimeware may take the forms of scripts, viruses, worms, Trojans or other malicious computer programs. this threats cannot be prevented! and thats the answer!. but yesterdays threats can be. and why? because virus scanner and other virus protection software are based on definition files.

do you wonder why virus scanners are always updating thier software thru online updates? this updates the definition files of your virus protection software to the latest and detected list of virus/threats.

now a virus definition file is a list of known virus, known meaning virus that the maker of the virus scanner software knows about. its like a list of criminals in the police station, criminal records of know person that is a criminal. so that when the police see's them they can be identified. now if there is a new criminal that is
not on the list. then there is no way crime can be prevented!. thats why to make this clear. todays threat cannot be prevented at all. with exception to elite computer users ofcourse. becase and elite computer user can and will identify computer threats on the spot. :) and for some reason 80% of the infection/cybercrime happens because of human stupidity..
