Grokster removal

Customer complaint: Teenager installed a program and Grokster was installed too. Can't remove Grokster. 

CA spyware scanner reports Grokster is still there. 

Solution: Checked Add/remove programs in Control Panel. Grokster was not listed. Looked in Program Files and in Registry for traces of Grokster - none found. 

Installed Malwarebytes, SuperAntispyware, and VirIT Explorer Lite. Ran full scans, not just quick scans. No problems found. Sophos firewall and antivirus was being used. Automatic updates was turned on. I told customer that I think that CA scanner is only finding some remnant file of Grokster and that the program is not longer on her computer. 

I recommended that customer uninstall CA spyware scanner and use the two programs I left on her computer - Malwarebytes and SuperAntiSpyware.
