Kaseya International software is for IT Managed Services Providers (MSPs) providing remote IT administration on client-owned network infrastructure. (Kaseya also offers Cloud-based (SaaS) services to smaller clients directly.) VSA is Kaseya's "Virtual System Administrator" solution. "KaUsrTsk.exe" is the Agent Helper Service, crucial to installation of the Agent function on both client and server platforms which keeps them connected with higher-level servers and reporting operational data to a remote administrator; it and the "Kaseya Packager" which installs the Agent are interdependent. It is a Windows service that starts with Windows and always runs. Double-clicking on the "K" icon it displays in the system tray brings up a webpage for submitting a service ticket to the MSP's support desk, although it can still be running if the icon is absent. Consult the support desk or "" before trying to uninstall or disable the Helper Service.
