I have no idea what that is?

but try repair

For a repair of avast. Windows, Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button from the pop-up window, scroll down to Repair, click next and follow.

What do you mean, “cannot fix it”? What exactly do you think that option will do?
