Well it would have been saved as a restore point on deletion/modification/moved, etc. that would account for the detection in the system volume information folder.
More important though what was the file name ?
What scan were you running when this was detected ?
You could also check the offending/suspect file at:
VirusTotal - Multi engine on-line virus scanner and
report the findings here, post the URL in the Address bar of the VT results page. You can't do this with the file securely in the chest, you need to Open the chest and right click on the file and select '
Extract' it to a temporary (not original) location first, see below.
Create a folder called
Suspect in the
C:\ drive. Now exclude that folder in the
File System Shield, Settings, Exclusions, Add, type (or copy and paste)
C:\Suspect\* That will stop the File System Shield scanning any file you put in that folder.
