Avast appears to be on a blacklisting stolen keys kick atm

[Legoman]

Just in recent days, formerly long term valid successfully registered Avast installations have been coming up as unregistered when doing their normal update 'phone home' checks. It's looking like Avast are having a clean out of valid registration keys that are being used too often. I've noticed a lot of the included keys in the warez distributions are now no longer working and can't be entered in the program subscription screen. Anyone else had a similar experience in recent days with Avast Premier?
