Well getting back to the issue of to reformat or not. Reformating is not that bad, just takes a bit of time. If you are worried about not setting up the computer the same way it was, then there was not enough sufficient backups being made. If your computer took a dump and you couldn't install all your old stuff, where would you be? ;) Not saying to do it on any virus, worm or trojan horse but when in doubt, wipe it out.... ;)
