更清晰的地址: If you have installed trial or paid licensed version of Corel software products, you probably may notice a third-party unannounced software application makes its way into your computer too. The program is PSIService.exe by Protexis, which installs a Protexis Licensing service or Protexis Licensing V2 service in Windows operating system.PSIService is part of Protexis copy protection DRM (digital rights management) and license management software, which intends to protect a software or application from piracy and illegal copying. Thus PSI service is normally installed by another program, such as Corel Paint Shop Pro Photo X2, Corel Paint Shop Pro XI (X1), Corel Paint Shop Pro X, that uses its service to gather licensing information to send home much like spyware, ensure copy protection and authenticate user that uses genuine version of the program.To make matter worse, the ProtexisLicensing service may make PC boots up slower, and when disabled, will cause Corel Paint Shop Pro to stop working, in addition to warn you of running illegal copy of non-genuine software. Besides, PSIService.exe does not uninstall together with the application that installed it, when the application is uninstalled and removed.In any case, whether you want to get rid of Protexis while keeping the application that dependent on it still working properly and able to run (contrary to popular belief, Protexis Licensing service is not required for program to run), or now need to clean the Protexis PSIService spyware manually due to non-removal by original application that installs it, the procedures to complete uninstall and remove Protexis is easy.
