    BSOD When Back up starts vhdmp.sys


    I am trying to solve a problem that every time the PC tries to make a back-up, I have turned off Bitdefender,and also tried changing the location of the back-up.
    Can any body advise please.

    As a temporary work around, use Macrium Reflect Free instead of the built-in Windows 10 Backup, see if that works. At least that way you will have a good backup. Then you can work on the vhdmp.sys problem.

    The dump indicates a problem with BitDefender anti-virus: avc3.sys
    ffff8301`bb8be4d8  fffff80f`813739f1*** WARNING: Unable to verify timestamp for avc3.sys
    *** ERROR: Module load completed but symbols could not be loaded for avc3.sys
    Driver Description: BitDefender Active Virus Control filter driver
    Driver Update Site: Support:
    Downloads: Download Antivirus Software - Bitdefender Downloads

    Uninstall BitDefender anti-virus.
    Make sure Windows Defender and Windows Firewall are enabled.

    Run that way for awhile to test, see if that resolves the problem.

    Note: Uninstall, not just turn off/disable.

    Hello Rich,

    After running without Bitdefender for nearly a week, I am glad to say that there have been no errors, and back-up has completed as it should.
    Many Thanks

    Sounds good. Are you still using Windows Defender or have you switched to another Av program?
