Those wondering when the Microsoft love-in with Citrix might end will be relieved to learn that Microsoft Defender decided yesterday that Citrix Broker and High Availability Services bore all the hallmarks of a trojan.

Administrators and users alike found that update 1.321.1319.0 of the malware masher left Citrix's platform a tad borked, with the Citrix Broker service gone from the Services console and the BrokerService.

The problem, according to Citrix, can occur on Delivery Servers and Citrix Cloud Connectors with Microsoft Defender installed.

Otherwise the broker services used to manage connections and sessions get shunted into quarantine and, alas, Citrix's wares are made unhappy.

Still, Citrix administrators will be relieved that at least the update did not sling an animated paperclip onto the screen, saying: "It looks like you're trying to do some virtualization. Would you like some help with that? Maybe with Windows Virtual Desktop in Azure?" .
