Hi
This table is used to temporarily store URL's found during a scan before we check them against the Google Safe Browsing (GSB) list of known malware and phishing URLs. This is used during a scan and in other places we check things against the GSB. You can manually clear this if you wish, but never while a scan is running. Its supposed to be truncated and cleared on each scan.
This table can be omitted from backups, so please exclude it if you have that option in your script.
