Since yesterday after the virus definition update AVG is deleting system file called user32.dll which actually causes either your PC go into continuous loop of rebooting or it just stops booting. AVG virus definition signature thinks that user32.dll is Trojan Horse PSW.Banker4.APSA or Generic9TBN.
This is how AVG responded:
Unfortunately, the previous virus database might have detected the
mentioned virus on legitimate files. We can confirm that it was a
false alarm. We have immediately released a new virus update
(270.9.0/1778) that removes the false positive detection on this file.
Please update your AVG and check your files again.The system can be restored by following the steps in one of the
comments on forum (using safe mode or recovery console and copying
c:\windows\system32\dllcache\user32.dll into the right location)If you need to restore deleted files from AVG Virus Vault you can do
it this way:
- Open AVG user interface.
- Choose “Virus Vault” option from the “History” menu.
- Locate the file that was incorrectly removed and select it (one
click).
- Click on the “Restore” button.We are sorry for the inconvenience and thank you for your help.
Best regards,
