Windows Defender update takes out Citrix – Security – Software

Citrix consumers have run into troubles with an update for the Home windows Defender antivirus application from Microsoft, which erronously flags two data files as Trojan horse malware, and stops the desktop virtualisation software package from working.

The problem is viewed with Windows Defender that has been given the antivirus definition 1.321.1319. update, and which is installed on Citrix Shipping and delivery Controllers.

Two data files, HighAvailabilityService.exe and BrokerService.exe are detected by Defender as Trojans and deleted, consumers noted.

Citrix is conscious of the concern and suggests that consumers who are afflicted by the problem attempt to restore the deleted data files from Defender’s quarantine, and change the Log On for the data files to Network Support in Home windows.

The data files need to also be excluded from Defender’s anti-virus scans, Citrix advised.

Right after the data files have been restored, the Citrix Shipping and delivery Controller desires to be rebooted.
