hi I have a problem with the manual update , when i start to install the update package ; a message uppears asking me to update the program version ( im using avast profess. ) but i dont know how to do this manually ???
to update the program update you just rightclick on the avast!-symbol in the taskbar go to ‘update’ and then choose ‘program-update’
then the new program-version should be downloaded and installed 
Probably you’re using a very old program version… which is it? You can go to ‘About’ dialog of the context menu of the ‘a’ blue icon on system tray.
THANKS ALOT , SUPPOSE I DONT HAVE AN INTERNENT CONNECCTION ? HOW I CAN DO THE UPDATE??
the only possibility to update without an internet-connection (on the computer with avast) is download the actual program or vps-installer from the homepage (on an other computer with internet connection)…
