Concern that “Cleanup may delete files that are identified as components and listed under Locations" may delete or damage disk image.

Quarantine Manager detects a threat on my iMac: Troj/Java-CM, (which affects Windows OS).

Location is:
/Users/bradconfer/Documents/Mercury C Archive/G4HD BatGyrl A.dmg

G4HD BatGyrlA.dmg is a disc image of a hard drive partition (hopefully bootable if ever restored), which is an archived backup of my other older G4 computer which I rarely use, which has Mac Tiger OS.

Item Status says “Cleanup is available for this threat” with the option to “Clear From List” or “Cleanup.” Pressing “Cleanup” I get warning, “Cleanup may delete files that are identified as components and listed under Locations.”

I don’t want my entire disk image to be deleted. Is Sophos warning me it might do that as the final file Location listed in Quarantine Manager is the disk image itself, not a cache file or anything else?

Will “Cleanup” possibly delete more than just the Troj/Java-CM threat and possibly delete or damage other components of the disk image, or the entire disk image, making it unusable or dangerous to use?

Thanks for your consideration!
