Can't open Avast after right clicking and disabling shields

[Mike7463]

I've tried double clicking the icon to open it and tried from the start menu, tried repair and reinstalled but it keeps happening, it has managed to open a few times from the start menu but it freezes.

- Which Avast..? (Free/Pro/IS/Premium)
- Which version/build of Avast..?
- OS..? (32/64 Bit..? - which SP/Build..?)
- Other security related software installed..?
- Which AV(s) did you use before Avast..?

Free / 20.3.2405 (build 20.3.5200.561)
Windows 10 64bit 1909 / 18363.836

I've got malwarebytes installed but I only use it for scanning, I disable all the protections and don't leave it running, I've never used another antivirus.

Edit: Tried a clean boot, disabled all services and startup programs but it still happens.

Regarding Avast & Malwarebytes, see: https://forums.malwarebytes.com/topic/200324-exclusions-for-avast-users/

I uninstalled malwarebytes, still the same problem.

1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.

Thanks for the help but that didn't solve it.

You could try the latest beta: https://forum.avast.com/index.php?board=15

Looks like that might have solved it, I haven't had a problem with it so far, thanks again.

You're welcome.
