It maybe false alarm done by antivirus. False Positives are harmless and legitimate programs that are incorrectly identified as malicious by an antivirus program.

"Antivirus systems sometimes identify applications as 'infected' when they are not (which is known as a "false-positive"). This could happen to RingCentral Contact Center desktop applications, as with any desktop application. If this happens, work with your antivirus vendors to resolve such issues. " as per the reference given
Three users reported this to me today and I just set another user up on a brand new computer an I was presented with the same alert. Here's to hoping it's just a false-positive.
The file Windows Defender is reporting a Trojan for is: Uninstall RingCentral.exe
RingCentral had an update to their app yesterday, the same time we got this alert...
This happened to me on Tuesday (9/8/2020) when I closed and reopened RingCentral. The file location was C:Users[username]AppDataLocalProgramsRingCentralUninstallRingCentral.exe.
I assumed it was a false positive, too. Some of my team's own beta apps have triggered false positives when unsigned.
Note that on 4/30/2020 I installed a beta of the new consolidated RC app (v20.2.11.1262) and then upgraded a few weeks later when it was officially released as v20.2.20.1473. There were some issues with uninstalling the three apps (Glip, Meetings, softphone) and installing the beta, and again when moving to the official release, so that may have left some remnants of the beta.
