hello, not sure what is happening with my avast but after the update, the Avast Service is continually running taking 30% of CPU nonstop. 3 reboots have solved nothing, neither has a full shutdown. why is this happening?? How do I fix this?

I updated my Windows 10 PC to Avast 20.7.2425 (build 20.7.5568.598) last night.
This morning on reboot, Avast took over the whole PC! Twice, the screen froze and
I had to crash and restart. The CPU usage is, as stated by others, insane: about
25% *each* for Avast service and Avast firewall service. The disk was grinding away
so much that no read/write operations by applications were possible.
I came across some articles about repairing Avast and I tried that. It appears to
have solved the disk issue (that is why I am able to type this!), but the high CPU
usage is still an issue. There are 5 Avast Antivirus instances in the Task Manager.
Power usage is very high, too. For the first time in the two years that I have had
this machine, I hear the fan running. I have 16 GB of RAM. Memory usage is also
weird: the Task Manager says I am using 97% of memory.
I went to the suggested page (
https://forum.avast.com/index.php?topic=237567.0),
but I confused by the very first instruction: should I download or not? As I have
the "newest" installation of Avast, how do get a log?
I did try to click on the link in this page to download (on Firefox) and I get is the
XML text -- no download.
Incidentally, in the time I took to type this up, the screen froze twice for about 10
seconds.
Need help to fix this. Would a complete uninstall and reinstall help? How can I
submit a log? I have already submitted feedback via the Avast GUI.
Thanks.
PS: Just as I was pre-viewing the above, the disk activity went back to 100%and the
machine froze. I had to crash it again. This time, I uninstalled Avast on reboot. Everything
is normal again:
CPU: 3%
Disk: 1%
Memory: 22%
Clearly Avast 20.7.2425 (build 20.7.5568.598) has a problem. Is there a fix
in the works?
