Nis 2010 - sonar failed to load. Module 3039, Error 65554

Hi can any body please help with this problem with NIS 2010.

After removing NIS 2009 and installing NIS 2010 ( Version 17.5.0.127)  every now and then I get a PC AT RISK pop up, on clicking fix now I get the following message- sonar failed to load with error code 65554 - contact Norton.

After spending approx four hrs with four different one click support personnel and being told the problem is with Norton services they informed me I need to speak to technical engineer by phone. Engineer rang two days later and after taking control of my pc informed me I need to speak to Norton virus removal services, after transferring me I was informed Norton could remove this virus for £69.99.

 

What is the point of NIS 2010 when I am asked to pay for a professional to remove a virus which I am sure I do not have after numerous scans and nothing found.

 

I cannot believe it is not possible for Norton to have no fix for my problem.
