Hello all,

Please see update towards the bottom of this post

we regret to inform you that latest virus database 271.1.1/3292 (432/3292) released 12:53 AM CET requested computer restart with inability to start the system again with error:


We have immediately downgraded published failing version to fully functional 271.1.1/3291 (432/3291).

If you have unfortunately met mentioned error, please follow these steps:

If is possible to boot into Safe Mode, then run System Restore before the night AVG update and re-install AVG.

If is not possible to boot computer at all, please follow this How-To.

Or use AVG Rescue CD -> menu Utilities -> Midnight Commander -> navigate to /mnt/sda1/program files/ (or program files (x86)) and rename by F6 AVG folder to other name (for example AVG_old).

Then start your system again and re-install AVG.

Please accept our apologies for any inconveniences caused by this situation.

Thank you

Update from Kodl:
This issue is limited to 64-bit systems only, currently it looks like not all 64-bit systems though, we are investigating. The updated has been pulled from our servers and if you have not been affected by this issue, it is OK to update normally.

We will release some tool to help in fixing the systems affected by this bug. Also, a few users here in the forum have posted excellent descriptions of fixes that do not require full use of the Rescue CD.
In short, during boot, boot into the command mode (pressing F8) and rename/remove the AVG program folder, then boot normally. After this, you can run the repair installation of AVG.
See for example an excellent description here http://forums.avg.com/ww-en/avg-free-forum?sec=thread&act=show&id=133009#post_133009 by Pulse21

Again, please, accept our apologies and stay tuned for a more detailed description and a fix

New information:

A) If you did not restart yet (due to AVG after-update request)
- delete all .prepare files from AVG program directory:

For 64bit operating system:
C:\Program files (x86)\AVG\AVG10

- open AVG -> menu Tools -> Advanced Settings -> Update -> Manage and use the button to remove temporary update files
- reboot computer
- run AVG 2011 repair installation to restore AVG to previous functional state - this may actually not be necessary in most cases
- everything should be working fine

---

B) If you did restart and have the unpleasant issue
- use AVG Rescue CD
- open menu Utilities -> Midnight Commander
- navigate and rename these files:

For 64bit operating system:
/mnt/sda1/program files (x86)/avg/avg10/avgrsa.exe
/mnt/sda1/program files (x86)/avg/avg10/avgchsva.exe

- use F6 key to rename them to some other name
- reboot computer
- run AVG 2011 repair installation to restore AVG to previous functional state

We are also working on some easier solution. We will keep you informed.

EDIT: FAQ 4080 created

EDIT: Encrypted disk partitions needs to be decrypted prior to using Midnight Commander on AVG Rescue CD. (TrueCrypt Rescue CD)

EDIT: FAQ 4080 updated with modified AVG Rescue CD for USB medium. It is enough to just boot prepared USB medium at affected computer and confirm changes. All needed actions are done automatically. Then please repair AVG installation.

Thank you for your cooperation.
