What does the scan status "rescan-outdated" mean?

Issue

Files entries in scan results of Malware Scanner have the "rescan-outdated" status. What does this status mean?

Environment

• Imunify360
• Malware Scanner

Solution

The "rescan-outdated" status indicates that a file has been changed in some way since the last scan by Imunify360’s Malware Scanner. This could happen for reasons such as:

• The file was modified or cleaned (e.g., by you, a developer, or another security tool).
• Imunify360’s malware definitions or scanning rules were updated, causing the file to no longer be classified as malicious.

Were these files malicious or not?

• Previously: They were flagged as malicious/suspicious at some point in the past.
• Now: The latest scan no longer considers them a threat (e.g., they may have been fixed, or definitions changed).

Did the Malware Scanner scan them or not?

• Yes, the scanner actively rechecked these files during the latest scan.
• The rescan-outdated status is the result of that re-evaluation.

Was any action taken on these files?

• No action is taken automatically for rescan-outdated files because they are no longer classified as threats.
• They remain in your history for transparency, to show that they were once flagged but are now considered safe.

Is it possible to remove the "re-scan outdated" entries?

There is currently no way to spot remove incidents from the scan history. You can completely clear the scan history by following the steps below:

1. Make a backup copy of the database first:

cp /var/imunify360/imunify360.db /var/imunify360/imunify360.db.bak

2. Open the database using sqlite3:

sqlite3 /var/imunify360/imunify360.db

3. Perform SQL request:

delete from malware_history;
