    We are also having this problem.

    Virus infected SSI=N Type=Anti-Malware Signature Virus=Gen.Variant.Fugrafa.398dff27 File=AcroRdrDCUpd2100120150_incr.msp Protocol=HTTP

    Latest definitions as of 4/21

    I'm concerned that this may impact a legitimate download.  Adobe products are full of security problems in a normal basis.  I would rather be up to date on this.  But then again, is this a source code supply chain attack and there is a virus embedded in this code update? I would like to think not, but in this day in age you can't rule it out. 

    Can anyone from ZYXEL comment on this issue?

    Hi @Przemek, @Ynnek, @KITNIIT, @mMontana, @trojan29, @jonatan, @FEL, @Bonnet, @Massimo_F, @ans, @kyssling, @Sam_MTF,


    For  AcroRdrDCUpd2100120149_incr.msp file that issue has been solved.

    Please update your Anti-Malware signature to latest version available.

    (Configuration > Licensing > Signature Update)

    Hi @ZachWest,


    What's the Anti-Malware signature version of your ATP200?

    (Configuration > Security Service > Anti-Malware > Signature Information)


    As far as we know, there’s no chain attack or vulnerability concern for current Acrobat Reader update.


    But as new updates for softwares release, it takes time to verify that update of software is clean and implement it to upcoming Anti-Malware signature version.


    So it’s always good idea to keep signatures up to date.

    (Configuration > Licensing > Signature Update > Action > Schedule)
