Urlclassifier2.sqlite

urlclassifier2.sqlite contains information on known phishing sites that is used to warn you should you visit one. The information is downloaded by default from a Google database once a day. This functionality can be modified or turned off in Tools -> Options -> Security -> Tell Me....

Originally, a file named urlclassifier.sqlite was used, but the format had to be changed because the file (obviously) contained references to phishing sites, which anti-virus software noticed and complained about. urlclassifier2.sqlite obfuscates the names of the sites to prevent this from happening.

Editing

urlclassifier2.sqlite is a binary SQLite file and should not be edited manually.

Moving

There is no reason to move this file as it's overwritten daily.

Deleting

Deleting webappsstore.sqlite will delete anti-phishing data. The file will be recreated and the data reloaded on next start up.
