currently checking avast on the other pc - it has xp and so far does not reboot other than to hang at the start up with some link that does not seem to work, doing an f8 safe mode boot soon as want the licence from Nod32 for the current vista pc
not sure why people have to swear at others when they disagree, but guess ray found out the result
never liked avg after it told me some suspect files were ok - just some trojans
