We have sent a false positive report. I recommend that you also send FP reports to Microsoft just in case. This is easy, here is how:
1. Visit the
Submit a file for malware analysis page on Microsoft website.
2. Fill out the form. You may need to sign in to your Microsoft account.
3. In the lower part of the form make sure that you fill out the fields as shown in the attached screenshot. You can also upload the file rfusclient.exe. You can find it in the C:\Program Files (x86)\Remote Utilities - Host\ directory. If it's not there - restore it from Quarantine in Windows Defender settings.
4. Click Continue. On the next page confirm form submission.
P.S. Microsoft has always been quick to resolve FP issues. Let's see if they manage to fix this one asap.
