If you have been receiving rectangular notification popups in the lower right corner of my screen in Windows 10 that contain the square white Windows logo and say:
PC is infected, Click to remove viruses: sarpolitex.ru
And you are not sure that this is a legitimate notification or if the notification is the malware and keeps popping up three times in succession.
In addition, you have ran your own PC anti virus software multiple times with no results of finding a problem.
