Possible conflict with Dropbox and Trend Micro (Dropbox freezing)

I am having the same issue and it is Windows 10 with latest update and pretty reasonable specification. I have been working on from 3-4 days and once disabled the Dropbox from Start Up then the laptop is fine otherwise it freezes in a minute from startup. You do not get chance to do anything.

Tried all the steps but no real luck, even reducing the processory from 100% to 85% but issue remains.

so really waiting to get this resolved or we might have to use ulternate solutions.

I'm having the same issue on a customers PC i disabled it from startup and manually opening it later and now the computer isnt freezing.

not an ideal solution but atleast they can use the computer :upside_down:

Using Windows 10, Trend Micro AV 

You are right Jane, after gone through this Blog and as it says "Solved" but did not help me at all. In our case it was not Windows latest Feature update 1803 as this started happening before.

In our case, the anti-virus ie Worry Free Business Security Services (Trend Micro) and Dropbox conflicting to a level that its making the device to freeze. Either disabled the Dropbox from Startup or Uninstallation of Trend help resolved the probelm straight.

I will be reinstalling the Trend Again and see if it helps.

Interesting. All of the problems we are having include Trend Micro WFBS-Services and Dropbox. The workaround is to disable Dropbox on startup and manually start a minute or two later.

Yes - understand that we can't rely on end users.

I'm going to work at this from both ends and have started communication with Trend Micro.

Thanks. What did you use to clean the registry?

OK - will try on an affected machine.

Strange that one of the laptops is brand new and has only just had both Dropbox and Trend Micro WFBS installed. The registry should be clean.

Hi folks,

I just wanted to post here to acknowledge that we are looking into a possible conflict with Trend Micro. I'll reach out to a few of you via email with extra debugging steps. 

Many thanks for spotting the issue!

Thank You..much appreciated. 

Unfortunately, this hasn't worked for us.  We have the issue on some machines (although not all) and for the affected PCs (my desktop included), the new patterns haven't solved it.

For information, I'm running pattern 14.295.00 ( updated 05/06/18 ) and Dropbox client v.51.3.65.  I set my client to autostart and it caused the PC to hang again, so I've now had to set it back to manual.

Hey mikemor22 - strange it's working on some PCs but not all. Assuming they're all under the same settings, we might need our tech team to investigate this further for you. Can you log a ticket on https://dropbox.com/support with the existing info so they can help investigate further?

You may also wanna do the same with Trend Micro as the issue was on their end. If you find any additional info that would be helpful to the community, feel free to post here!

Thanks

This is also still happening for me.

I'm using virus pattern 14.309 with dropbox 51.4.66

Hi all,

Thank's for flagging that this isn't fixed for all, we'll loop back to Trend Micro and discuss it further with them.

Can those still hitting the issue confirm that they are running Trend Micro Worry Free Business - and have our Smart Sync?

I'll update here again once we have more to share.

Many thanks.

Thanks Ross,

We have also logged a ticket with Trend in Australia as we had same issue in our company which started approx . June 15th -  Look forward to any updates.

I would like to update that problem came back again few days back and eventually we just replace the Trend with another AV. As it was the only device with Trend, so easy to replace, as can not afford to spend time again and again. Client getting bit frustrated.

Hi,

We tested a fix for the last two weeks over 30 PCs that has worked for us.  It was advised by Trend.  The core of the problem to me seems to be that because the Dropbox client is so file system and CPU intensive (across all cores) it is constantly causing red flags with the behaviour monitoring components of Trend and creating a vicious circle.

The below only exempts the specific executables, so you're Dropbox folders are still bein protected.

Add the following in the exclusion lists: 

C:\Windows\System32\DbxS​vc.exe 
C:\Program Files (x86)\Dropbox\Update\Dro​pboxUpdate.exe 
C:\Program Files (x86)\Dropbox\Client\Dro​pbox.exe

*Antivirus/Antispyware 
1) Go to your WFBS Services console 
2) Under the Devices tab, click the group of the endpoint where you want to apply the exclusion 
3) Click Configure Policy 
4) Under Antivirus/Anti-spyware, click exclusions 
5) Enable exclusions and include the path or file that you want to exclude 
6) Click Save and wait for the agents to be notified 
7) Verify that the file is excluded from being scanned 

*Behavior Monitoring 
1) Go to your WFBS Services console 
2) Under the Devices tab, click the group of the endpoint where you want to apply the exclusion 
3) Click Configure Policy 
4) Under Behavior Monitoring, enable behavior monitoring 
5) Add the full program path of the program/file that you want to exclude from scanning to the approved list 
6) Click Save and wait for the agents to be notified 
7) Verify that the file is excluded from being scanned 

After adding the files indicated above on the Antivirus/Antispyware and Behavior Monitoring exclusion list, then please restart the machine and continue monitoring.
