GamyunIe is an adware program.  It will install a toolbar into Internet Explorer by way of a BHO, or browser helper object.  BHOs are used because most firewalls do not detect them, and they are able to accomplish their stealth operations undetected.  This malware will wait in silence until you launch your Internet browser and then you will be flooded with pop-up advertisements.  Leaving this malware on your computer poses a risk to the proper functioning and health of your computer.
