in the sense that in some cases it takes a while to connect with the server, so I cancel update, get the 'system at risk' message re-boot and re-check and it goes OK.
Updated this morning and found the "preparing to install" was slow. It then froze when the green bar had travelled all the way across. Turn AVG off and even disconnected from the interface, but when I restored it the picture was the same. Tried turning off through the windows task manager. It turned off the program but when I went back in.. same problem. Shut down computer but it froze (probably because it could not close AVG) so I had to shut down manually. Rebooted and AVG updated as usual.
Not a "problem" but I wondered if anyone else has encountered this glitch?
