  7. Greatly improved performance of content filtering scanning.
  8. File Type Filter now has the lowest possible level of confidence for the determined file type.
  9. The antimalware engine is now better protected from viruses specifically targeted to kill the antimalware engine (archive unpacking bombs, artificial looping in archives and so on).
  10. Decreased the possibility of errors because of antimalware engine timeouts in traffic interceptor.
  11. Extended patterns for File Type Filter.

Known issues and problems

  1. Due to the way Mozilla Firefox downloads online PDFs, it may not be possible to download PDFs if partial download is prohibited.
  2. Traffic interceptor is not always able to get the filename of downloaded object out of HTTP response, thus some filename patterns may not always work in File Name filter.
  3. Continuous start/stop of Content Security 6.0 service may sometimes result in access violation in antimalware server qlscand.exe. This does not leave your proxy unprotected as without running service the protection is not able to run anyway.
  4. Check mark indicating currently selected content filtering module view may be set incorrectly when Back/Forward toolbar buttons are used.
