LexFloatServer.exe Trojan:Win32/Wacatac.C!ml

Windows Defender has quarantined the LexFloatServer.exe with version 4.7.1. Newer versions were quarantined aswell. The defender did not detect the newest version as an issue. I’ve downloaded the 4.7.1 from portal and verified the checksum with my pre existing one downloaded months ago.

This appears to be a false positive. Could you please confirm that?
