From the Wiki article you cited. “””Once PCKeeper is started, it will do a fake scan on your computer that will state that there are numerous infections or problems present. It will then prompt you to remove these so-called infections or problems, but will not allow you to do so unless you first purchase the program. Please understand, that PCKeeper is scripted to show you these fake scan results regardless of the computer you are on and how clean it is. Therefore, do not be concerned by any of the scan results as they are only being shown to scare you into thinking that you have a serious problem””””
Identical to what I experienced. Just a Slovakian scam!!!!
