talpa-deny errors preventing backups on ubuntu 20.04

I run sophos free SAV: 9.16.2, Engine: 3.79.0, Data: 5.77 , with talpa . Sophos Anti-Virus is active and on-access scanning is running

I use 7z to backup my files on ubuntu 20.04. Some of these files are from wine, and get talpa-deny errors in the system log, causing the backup to report timeouts, lock up and then have to be stopped.  However, I don't get virus alerts for these talpa-deny events.

An example from the syslog (my directory being replaced by .....) is:

kernel: [ 5994.994356] talpa-deny: Timeout occurred while opening ......../.wine/drive_c/windows/syswow64/mmdevldr.vxd on behalf of process 7z[7429/7429] owned by 1000(1000)/1000(1000) <62>

How can I
a) detect this better than just getting a syslog error
b) prevent it from happening
