This company has a software under name "C0ntext Menu Platinum" that installs a kind of Malware on your computer and a pop up windows opens up and warns about its Unregistered Version, although the program itself is not installed on the computer. There is no way to get rid of this pop-up window. There are many people who suffered this and tried to contact the support team which its e-mail address is provided, but the received no answer. The question is that how a company would be so stupid to forget to put an Uninstall option for its program, if I ever installed the trial version of the program, which I can not find it on my computer or they are trying to force people to install their program ...
PS: See the attached file for the pop-up window
Some cases that people are talking about the issue on the internet ...
