Hello this is a retweet from other Avast forum Section:
https://forum.avast.com/?topic=186688.0
in short:
OS: Windows XP SP3
Avast Version: Avast Buisness Free
After install AVASTCLEAR and the order to reboot in safe mode the PC creates a endless bootloop.
only “recovery Console” is working. the other things make a automatic reboot with Stop Error 0x0000007b
any Idea , my father dont have any backup and he uses it as architekt and heat protection calculation ?
maybe booting from Ubuntu CD and delete any Avast exe or driver ?
hope someone got a Idea
