  • Same Problem, today. Maybe Antivirus Database Update are corrupted.

  • Thanks for sharing! Any resolutions or fixes you guys had so far? 

  • I found some way. I send to here for discussion to fixit
    Reason: malware enabled on my FW rule to handle endpoints, using the sophos engine.  Sometimes the sophos AV pattern update fails.  When this happens, it breaks access to the web. if turn it off it fixes

    Some way I find on Internet, I send here to disscuss

    Note: I do nothing any of the methods below


    tail -f -n200 /var/tslog/up2date_av.log

    Try to stop and restart AV service?

    # Solution 2

    2. Now update the pattern files with the GUI using System > Administration > Updates.

    # Solution 3
    1. change the malware engine from sophos to Avira - in the GUI under System Service --> Malware Protection
    That should temporarily fix the problem.
    2. Just run the command
    mv /content/u2d/pattern /content/u2d/pattern.old
    3. click update the patterns in the GUI again, that pattern file should be recreated.
    4. don't forget to change back to using the sophos malware engine.

    # Soution 4
    re-image the device and restore from backup

  • Thanks - so you only stop and start the AV Service?

  • Pls check log file: tail -f -n200 /var/tslog/up2date_av.log, if Av update fail, the first way doest fixit
