Hi Wonder if anyone can help. I was running AVG Free 10 perfectly happily, and it prompted me to upgrade to 11. Why not, I thought? So went through installation, then it said finally machine needs to re-boot to complete installation. Did this, but PC froze in re-boot, wouldn't respond to keyboard, mouse, power button, nothing. Had to turn off at power socket, which I hate doing. Anyway, PC working ok today, but AVG came up not installed, saying "you need to re-start your machine to complete AVG installation". Done that twice, same message comes up. Tried to download free from cnet, it runs through the installation, but then the same error message comes up - so I'm left unprotected at the moment. Does anyone have any solution!?! I'd prefer to continue with AVG Free as I know it.
