just a warning if you go to download Quest for Glory 4 1/2 and click on go to website you get this virus free ,gratis as a bonus!!!!! :o
js noclose isn't a virus, it's just the name that some AV companies give to javascript that does popup ads.
The QFG4.5 site isn't working at the moment though -- and in fact very rarely does, so your best bet is to download it from Underdogs I'm afraid
