Freezing mouse and other suff

[Maureen L Thomas]

So I have the latest stable Debian installed on my Lenova all in one 
computer.  I have an 8gb seagate ATA  harddrive, Inetl core i3-9100T CPU 
310 GHz, Realtec 8821CE wireless lan 802.1ac PCI-E Nic.

When I shutdown I get the following message:  stop job is run for Clam 
Antivirus userspace daian   /1min40S  and them failed unmount /var.

When I boot up 1.290210] mce:[Hardware Error[:  CPU 0:  Machine Check: 0 
Bank 9: ae0000000036

1,290283] mce: [Hardware Error]: TSC 0 ADDR 8d387240 MISC 7040000086    
and then

1.290354] mce: [Hardware error]: Processor 0:906eb TIME 1688865217 
Socket 0 C O microcode f0


Also my system freezes, I thought it was just the mouse but it is the 
whole system.  It usually happens when I have more than four windows 
open or after I play music.  I have absolutely no idea what is going 
on.  Your help would be greatly appreciated.  Thank you.
