KAV 1.4 and major issues (with Google Sync)

  • I've been rolling out KAV 1.4 onto our machines and have run into a number of issues. Ranging from Kaseya not recognizing what version of Kaspersky is installed to uninstalls failing and breaking the USB drivers on a machine. I had been going through and manually fixing these but there is no reason for this, why is the upgrader unable to see what is installed when I can see the version clearly displayed inside K2, or even better, why is that causing a failure when it appears that the upgrade has to uninstall and reinstall the AV anyway. Of course I may be misunderstanding how that works.

    The most recent issue is one with 1.4 and computers that have outlook 2010 and google apps sync. The outlook plugin is causing a total block of outgoing messages on machines that I've upgraded. Disabling the mail plugin does nothing to stop the issue. I've seen a registry entry to change this but why should I have to disable the plugin on all our machines that we have upgraded, this just leaves the application vulnerable and kind of defeats the idea of an anti-virus.

  • I thought this thing was tested before release?

  • Update: Been rolling out 1.4 randomly at sites. A few bugs, but the dang thing actually works right !!!!

    However, have not installed on machines with outlook 2010 and google apps sync as noted above.

  • I configured KAV 1.4 to not scan IMAP accounts and that resolved the Google Sync issue.

  • I have disabled the Mail Anti-Virus and Anti-Spam components but the user still cannot send an e-mail.  I have also included an exclusion on the folder C:\Users\USERNAME\AppData\Local\Google\Google Apps Sync, but it still won't send out an e-mail.

    To further clarify the sending e-mail problem, when you click Send, the e-mail briefly displays in the Outboox and then appears in the Sent Items as a sent item, including the theoretical date/time as to when it should have been sent.  However, the end-user never receives the e-mail.  Every indication is that it is actually leaving Outlook, but somewhere along the way it is not being delivered to the recipient (I have checked log files, spam filters, etc.).

  • I was also having this issue with office 2010 and KAV 1.4 and I found this link from the Kaspersky's support


    In the forum it was version 8 of the business edition and I know KAV1.4 is built on version 6 but both seem to be having the same issue.

    I tried what was in that forum and that worked for me but I didn't want to have to do that for everyone with Google App Sync so I used KES on those machines instead.

  • Using a combination of what is on the Kaspersky site and the difference in versions, this is what I got to finally get it to work.

    1.  First off, just unchecking the add-in box for Mail Anti-Virus does not work.

    2.  There are two registry entries that need to be made



    The "LoadBehavior" value needs to be set to a value of 2 for both of the plug-ins.  Even if you uncheck the box to disable the the plug-ins within Kaspersky, both of these values will still be 3.  Changing them to 2 and restarting Outlook is what got it working for me.  Doing just the Anti-Virus plug-in did not work, you also had to do the Anti-Spam plug-in also.

    Of course, you could just KES in it's place, but if you are like us, we have been migrating all of our users from KES to KAV.

  • Thanks, this was very helpful and fixed the same issue for me. Although, on my system they are in HKEY_LOCAL_MACHINE not HKEY_CURRENT_USER.



  • I went back to the Kaspersky forum site and saw that they had a patch available for the Business Edition 8.x to fix this issue.

    I wonder if they have one for version 6 and if we will be getting that patch with our KAV updates.
