    Users that reported this issue through support tickets have mentioned that after reinstalling the latest versions of their antivirus, as well as the Dropbox desktop application, the message doesn't appear anymore and the issue is resolved.

     

    Please try with this and let us know if it's not the case for you. Please also let us know what are the versions you're using.

     

    Thanks!

I have the same situation as UR1ofTHEM.  The file in question is not in the cache.  It is in the path C:\Program Files (x86)\Dropbox\Update\Install\{06CD02FF-6D05-4F19-B801-C267B1180070}

 

I suspect it may very well be a legitimate file/update to the Dropbox Program, or it could be a trojan ransomware virus monster from hell.  How do I confirm through Dropbox.com, or wherever, if it's legitimate.

Thanks for keeping me updated on the progress here CagleTech! 
 
We’re currently looking into the behavior you’re experiencing internally & I’ll make sure to get back in touch with you here once I have more info on my end. Based on your description, the quarantined file resides in the Update folder & it should be relevant to the latest Stable Dropbox version (49.4.69), therefore it's not malicious.
 
If I were in your shoes, I’d disable, or uninstall Norton while the upgrade goes through, and then re-enable it afterwards. 
 
Meanwhile, have you contacted Norton’s support team on the issue by any chance (as the error message is on their end)? 
 
Please do let me know how the steps above work for you in your next reply & I'll make sure to get back in touch as quickly as possible!

    For what it's worth, I submitted this file to VIRUSTOTAL.COM and it came back clean.
