Hi Dropbox said "Through my research I found that this selective sync issue you are experiencing, appears to be related to your antivirus program Kaspersky. This program appears to be blocking and possibly blacklisting the Dropbox application every time it updates on your device; with this your selective sync preferences are being erased when you perform your first login after the update that has occurred on the application. To get this issue sorted I''ve passed your report along to our engineering team who will endeavor to fix it. However please note that this can take some time as the issue is related to another application on your device, and as such our engineering team will likely need to reach out to Kaspersky for true resolution." I am not sure I believe DB. The problems only appeared after I allowed the update to the new windows interface. How often is DB updating via your Kaspersky software? I dont know it has been auto updating. I have turned autoupdate in Kaspersky off. Have you added an exclusion for C:\Program Files (x86)\Dropbox\Update\ ? No I will findout how to do that. Are you also using KTS? If “yes”, please post back the version & patch information? app version 20.0.14.1085 (e) Go to KTS Reports, select All Events, select 24hrs or 7days, whichever period reflects a Dropbox Update, select Export, save the report as a .txt file & attach to your reply please?This doesnt make sense to me I hope it does to you (I selected entire period but it should be more) Thanks Dave
