Cathy v2.28.3 (latest version) disk cataloging tool

Now this one is strange. Sometimes Avast! Sandbox pops up when I run Cathy and sometime it doesn’t.

VirusTotal scan ony had Symantec find a problem, and that was a WS.Reputation.1 which basically sound similar WOT scorecard.

Just how much credence should I give to Avast! Sandbox?
