I already have posted in Italian section, but I would know if someone other has the same problem. Are about 3 days that I can’t update avast 'cause it always answers “there has been an error and avast can’t update. Retry later”. I tried to repair it, but there was nothing to do. The error is there again…
Do I have to uninstall it and install it again?
Here below a shot of the answer from Avast window
Thanks, but I was afraid to wait and I soved by myself.
Downloaded avast setup oiffline, switched off the connection and uninstalled actual avast. Cleaned registry with wise registry cleaner free; searched for folders and refuse files about avast to be deleted… Reboot computer and install new avast. Let it load all and do a reboot again, but this time switching on the connection.
Now everything works fine.
