I found the solution by doing these simple steps:
the following commands should be run from the root terminal
sudo mkdir /media/[Dir on SysRescue]
mount.cifs //[IP Address]/[Name of share] -o ro,username=[username that has access rights on the share] /media/[Dir on SysRescue]
example
sudo mkdir /media/share
mount.cifs //192.178.234.3/share -o ro,username=marino /media/share
after executing these commands a folder will be created in the preselected destination (in read only unfortunately, the -o rw:read write option doesn't work) and on the newly created folder a logical reference to the shared resource will be created on a Windows network competitor. After executing the mount.cifs command, the password for the user authorized to access will be requested. the resource will now be available in the ESET GUI for the next scan (without cleaning because it is read-only). I didn't run any sudo apt update & upgrade. I hope it will be useful and I am available for further suggestions on the matter. A warm greeting. Marino
