When Webroot performs the scheduled scan of a Windows Server 2012 R2 VM it appears to get stuck and uses all the CPU.

 

Server is the domain controller and is running a couple of SQL based applications and hosting shared data for a small business.

 

I have tried reinstalling the programme, renaming the WRData directory etc. Most times when I reinstall or restart Webroot and do the initial scan it completes in around 10 minutes. About every two days I get a call from the customer advising they cannot work. Restarting the server appears to clear the issue. I have looked at other threads relating to similar issues but have not yet found a permanent solution. 

 

Any thoughts on what I can try next to get this issue fixed please?
