It has been reported that some machines are unable to boot after the last AVG 2011 update version 3292. We recommend NOT REBOOTING/SHUTTING DOWN the Machines which have AVG 2011 installed on them.
More information is available in the FAQs below:
Please note that both AVG Pro and AVG Free can be impacted. Older AVG versions (9.0, 8.5) are not affected.
The situation has been caused by an incorrect CTF file used during the update (AVG 9.0 core has been offered to AVG 2011 clients).
AVG is currently working on a solution (utility) for all affected users, both those who have not restarted their computer yet and also those who were already affected by the BSOD.
The FAQs will be updated as soon as the utilities are ready.
If you are unable to boot to your operating system after the last AVG 2011 update 3292, it is necessary to do the following to solve the situation:
Download, create and run the AVG Rescue CD as mentioned in AVG Rescue CD guide.
Select the Utilities item in the main menu and run the Midnight Commander file manager.
In Midnight Commander, navigate to the following folder:
mnt\sda1 (if you have more disks, number can vary)
Then navigate to:
Program Files\AVG\AVG10 (32bit operating system)
Program Files (x86)\AVG\AVG10 (64bit operating system)
Find the following files:
avgrsx.exe or avgrsa.exe
avgchsvx.exe or avgchsva.exe
Delete both files by pressing the F8 key and confirm the deletion.
Quit the Midnight Commander and reboot your computer by selecting the Reboot option in the main menu.
After logging to your operating system, please download the latest AVG installation file, run it and when asked, choose the Repair installation option.
Please note that older versions of AVG (9.0, 8.5) are not affected.
