This is no adware son... This is a utility that is installed onto your computer in a Symantec Antivirus Application. This however, is 100% spyware and is illegal. I advise you to use Panda AntiVirus Titanium or Mcaffe AntiVirus. The purpose of this application is to protect CD, DVD, and download infringement and prevents the use of reverse engineering software.
