BSOD System Crashes

I am getting system crashes (Blue Screen of Death) whenever I run a new program. Turning off or uninstalling Avast fixes problems.

BSOD says:
Unexpected Kernel Mode Trap
FLTMGR.SYS

When I run dumpchk.exe on the memory.dmp I get:


  •                                                                         *

Use !analyze -v to get detailed debugging information.

BugCheck 7F, {8, ffffbf8019dca050, fffffc0bdf6fd000, fffff80bcc6659e7}

Probably caused by : mozyFilter.sys ( mozyFilter+479d )

The full bugcheck is attached. Have tried uninstalling and re-installing Avast. Only started in the last week or so (today is 22-Aug-2018).
Running Windows 10 64-bit, and am up to date with Windows updates.

Update to the latest version (18.6.2349): https://forum.avast.com/index.php?topic=221320.0
