I moved this to Malware Discussion > Corporate User Assistance.
Whilst I normally only help out on the home user forums , some of the software we use there may help you.
Try running Adwcleaner and Malwarebytes Free, both linked in the last link below.
(Note: to keep Malwarebytes free o0f charge do NOT accept the free trial offer nor activate it - simply update whenever you use it.)

Am unable to gather much data for this application. I get an impression that this might be a special application designed for Students in Warsaw University (Ever visited Poland once).
You need check the directory where this application is installed so that we can try removing it manually. Please provide more info such as your Operating System, Web Browser, and App details so that we can dig into this..!
