Avast! Offline Update
With the blocking of Iranian IPs by the Avast antivirus update server in early June 2012 , it became impossible to update the company’s products online from within Iran. For this reason, the offline update file of this antivirus was placed on the PC Download server, and by providing it regularly, users will be able to update this antivirus.
How to use:
After downloading the file and extracting it, just run it once to update your antivirus .
