Windows 8

My Avast 7 is giving conflict in windows 8 what should I do? Every time I install when I restart the machine and the computer is locked.

is this a brand new computer?..what type

is not a new computer is a notebook already used. In windows 7 I also had this problem longer only used avast 6 because when would update avast pro 7 it also gave conflicting.

OK…so there is no other antivirus installed on it?
new computers often have a preinstalled trail version from factory…and since you say win8 i was thinking new

or not wanting to be formatted after it becomes new.

Sorry, I don’t follow that comment ???

I think he’s trying to say he doesn’t want to format it again and start all over.
