Problems for those using AVG 2011 Free edition continue, with a update for the 64 bit version for Windows 7 totally bricking users computers. The last update from AVG 2011 Free edition causes the computer not to boot and displays error message c0000135. The problem has been attributed to database update 271.1.1/3292 (432/3292).

Here is how to fix the problem if your computer becomes the victim of the problematic update:

How to disable AVG when the operating system cannot be started properly

If you suspect that an AVG component is preventing your computer from starting properly, follow the steps below to verify the situation.

1. Use AVG Rescue CD to boot your computer.

2. When the AVG Rescue CD is launched, select the Utilities -> File Manager menu item.

3. Navigate to the mounted system drive. This will be /mnt/sda1/ in most cases.

4. Within this drive, navigate to the /Windows/system32/drivers/ folder.
– Rename (using the
F6 key) all files starting with avg (e.g. avgldx86.sys, avgtdix.sys, etc.) to back them up. You can change their extension from .sys to .bak, for example.

5. Press CTRL+ALT+DELETE and reboot the system (make sure to remove the AVG Rescue CD from your optical drive before doing so).
– Your system will boot without AVG being involved in the process.

On October 5, 2011 I wrote an article about some of the problems I personally experienced when upgrading from AVG Free 9 to AVG 2011 Free edition. In that article many people had posted their experience with the new version. It seems that the problems for AVG continue.

Comments welcome.
