CATIA Composer/frequent corrupted smg files

is there any official Dassault recommendations about specifying antivirus exclusions for trouble-free use of their products?
we often encounter file corruption problems when saving and reopening smg files localy or over the network, catia v5 or catia composer. 

i have many doubts about defender settings, any official directive would help to request antivirus exclusions from my security team before suspecting CATIA softwares.
