Antivirus false positive

[twgoff]

I am getting a malware error when trying to install the latest version 2.3.37.

Whenever we make a new upgrade and create a new build to distribute to our users, Windows may temporarily block the installation because the file is new and Windows doesn’t have enough information to guarantee its safety. It can take a few weeks for Windows to remove this warning. Luckily, you can accept the downloaded file

I was able to exclude Forscan from my virus scan and it now works.

We tested 2.3.37 on virustotal.com before the delivery, it didn't show any detections with Microsoft. It started to show it only on December, 1st. So either the site (virustotal.com) has problems with antivirus update, or Microsoft identified 2.3.37 as a threat AFTER the release.

Anyway, we have submitted the report to Microsoft, hope they will remove it from Defeinder soon.

Update: got word back from Microsoft that they have removed the false threat for 2.3.37:

Analyst comments:
