Hello Aleksa,
I do not know what that is, someone else may have to shoot in here if they do, but I can troubleshoot some things with you for right now.
What antivirus software do you have? You might download and install
malwarebytes with whatever it is that you have, as it can provide further help in identifying and removing malware.
Let me know what antivirus software you have as soon as you finish updating malwarebytes and performing a full scan.
Also, please f
ill out your system specs (this tool may help you out a great deal). This way I can offer some more suggestions based on what hardware you have.
