Zip Bomb

I created a full backup of cbu type (selected folders only) and encrypted with a password. Later I scanned my computer and external backup drives for viruses. I received an error regarding a possible “Zip Bomb.” I know sometimes anti-virus software “thinks” there is a virus when it is actually a component of an application, and am wondering if that is the case here. Please advise what you make of this. This is the specific error message:

“System Volume Information_restore{46DE8921-1D39-44D2-A9E9-64119261F211}\RP263\A0010823.sys - appears to be a ‘zip bomb’”

???

Since the file is in “System Volume Information_restore…”, I think you can delete it.
These files are used only for System Restore Points and they don’t have anything to do with CB.

Thanks
