FREQUENTLY ASKED QUESTIONS
Clear answers before you scan.
Learn how USB Guard handles files, malware scanning, reports, privacy, and system requirements.
Click any question to reveal the answer.
FILE CONTROL Does USB Guard automatically delete files?
No. USB Guard reports suspicious or infected files but does not automatically delete them. You remain in control of what happens next.
RISKY FILE TYPES Are EXE, JAR, BAT, or VBS files always malware?
No. These file types may be legitimate, but they can execute programs or scripts. USB Guard identifies them for review rather than automatically classifying them as malware.
SCAN ENGINE Does USB Guard work without ClamAV?
Quick file-risk analysis can still work. Full known-malware signature scanning requires ClamAV to be installed and available.
REPORT STORAGE Where are scan reports saved?
Reports are saved in the Monceda USB Guard reports folder inside your Documents directory.
PRIVACY Does USB Guard upload files to the internet?
No automatic file upload is performed. Device inspection and scanning are designed to run locally on your Mac.
PROTECTION SCOPE Is USB Guard a replacement for full antivirus?
No. USB Guard is a focused USB inspection utility. It complements broader endpoint protection but does not replace complete system security software.
