Ad.FLVPlayer rules are part of the first signatures that are tested. If the scanner does not progress, it is possible the scanner service crashed. This should be visible within the eventlogs or in the 'Scanner.log' file. Please check this logs, if there is any evidence for a crash.

Zlob.zipCodec rules are part of the last signatures that are tested. So the scanner progressed, but stops during the 'downloaded files' scan. This is the last scan phase. The file system was already checked, just the user defined directory set is
about to be scanned in this phase. So how big is your directory set?

1. Run Setttings.
2. Select the 'Download Directories' tab. Are there any directories set?

Kind regards,
