1st person shooter/virus scanner
My idea is to combine a virus scanner with a 1st person shooter (eg: quake). The program could be run in different modes:
1/ Scan your machine for viruses = serious virus scanner with std anti-virus type gui.
2/ Play the built in game independently of virus scanner = self explanitory.
3/ Scan your machine with game front end = Game starts - virus scanner scans your machine in the background while you play the game. The game would be just like any other 1st person shooter - mazes, bad guys, etc. Any viruses found would spawn new "Special Bad Guys" in your vicinity in the maze - a new bad guy for each virus found. The bad guys could have descriptive labels above their heads to signify that they are indeed a virus, and of what variety. When you kill the bad guy, the virus is deleted. At the end of the scan you would have the option to continue the game, or quit. Quitting would automatically delete/cure any viruses that you missed killing off in the game. If your machine is badly infected and there are too many bad guys to kill off - you would be presented with an option to return to the serious antivirus front end to save on system resources.
