Hi,

The fix should be released in the next beta version.

This problem is caused by conflict with Zemana AntiLogger/AntiMalware. Zemana seems to intercept normal process creation flow using method, which is not compatible with Avast self-defense. Microupdate for 20.4 version will be released.

The incompatible Zemana's driver is C:\Windows\System32\drivers\antilog64.sys. This driver is not correctly uninstalled with Zemana's uninstaller so it stays in system even after uninstallation of Zemana's product. It must be removed manually.
You can check for presence of this driver in your system by executing in elevated console:

sc.exe query antilog32

SERVICE_NAME: antilog32
        TYPE               : 1  KERNEL_DRIVER
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0


You can remove this driver manually by executing:

sc.exe delete antilog32
[SC] DeleteService SUCCESS


After deletion of the antilog32 driver service and reboot, you can also delete the driver file:

del c:\Windows\System32\drivers\antilog64.sys

I followed the detailed instructions @Spec8472 gave, then rebooted, re-installed Avast, ran the first scan, then rebooted.

Everything worked as it should... NO SUSPENDED Avast processes, and the Avast is in the task bar.

Thank you for solving the problem.
