Ok this problem might occur when BullGuard is trying to write some register keys and because of lack of permissions or denial of access it is not able to do that. So I would suggest you the following suggestions work on it and let me know if that was of help for you or not.
1) You need to uninstall the bullguard and then reboot the system in the normal mode.
2) In the command prompt type the following command sfc /scannow and press enter. Now the scanning will start, allow it to finish.
3) Now here comes the very important step. You will have to reset the register permissions of Bullguard antivirus, for that what you have to do is
- Download the SubInACL tool that you will find in google. Now go to the accessories, in the command prompt right click on it and select ’ Run as administrator’.
- Open a notepad and rename it as ‘reset.cmd’.
- Copy and paste the following command in the notepad.
Code:
“cd /d "%programfiles%\Windows Resource Kits\Tools"
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f /grant=restricted=r /grant=YOURUSERNAME=f /setowner=administrators > %temp%\subinacl_output.txt
subinacl /keyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f /grant=restricted=r /grant=YOURUSERNAME=f /setowner=administrators >> %temp%\subinacl_output.txt
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f /grant=users=r /grant=everyone=r /grant=restricted=r /setowner=administrators >> %temp%\subinacl_output.txt
subinacl /keyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f /grant=users=r /grant=everyone=r /grant=restricted=r /setowner=administrators >> %temp%\subinacl_output.txt
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f /grant=users=r /setowner=administrators >> %temp%\subinacl_output.txt
subinacl /keyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f /grant=users=r /setowner=administrators >> %temp%\subinacl_output.txt
subinacl /subdirectories %programfiles%\ /grant=administrators=f /grant=system=f /grant=users=e >> %temp%\subinacl_output.txt
subinacl /subdirectories %windir%\ /grant=administrators=f /grant=system=f /grant=users=e >> %temp%\subinacl_output.txt”
- Now don’t forget to change the values of YOURUSERNAME with the Windows user account.
- After having done that save and close the notepad. Now in the command prompt type the following command reset.cmd and run it will reset all the registry files.
4) Reboot the system and then reinstall the BullGuard antivirus back in the system. That’s what you should be doing.
