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:
STOP: c0000135 The program can't start because %hs is missing from your computer. Try reinstalling the program to fix this problem.
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.
