    I've got a pc running Windows 8.1
    64-bit, 4gb of ram. Whenever I open Windows defender, an error message pops up. I need help.

    Google 0x80073b01 and you will find a MX Fixit link

    Are you running any other security type software apart from Windows Defender, such as an Anti-Virus or Anti-Malware program, or a security suite ?

    Try disabling Smadav and restarting the computer and see if you can update Windows Defender then.

    Try it first, if it doesn't help let me know in your next post here.

    Please don't use Registry cleaners/optimizers they can do more harm than good.

    You're welcome. It might be best to restore the backup before disabling Smadav.
    What software did you use to make the backup ?

    Registry recycler was the software I used to clean it and it made backups before the cleaning. I restored the backup, deactivated smadav, restarted the system but nothing. It's still showing the same message. What do I do?
