Windows 8Which is better, Norton 360, Advanced Tech Support, Panda or PCMRI?

Windows 8

Just purchased a new PC 08-19-14.  I activated some software and a notice came up to call Advanced Advanced Tech Support.  I called and they ran a scan on my PC and found 105 warnings/red flags that they said needed to be fixed.  Now they want me to purchase a Full PC System Cleaner that weill fix these warnings/red flags, speed up my PC and prevent these warning/red flags in the future.  They want me to purchace Panda ($499) and something called PCMRI.  I have used Norton 360 since it first was released.  Did Norton360 miss these warnings/red flags?  Advanced Tech Support wants to run a Tune-Up on my PC, is it wise.

 

I do have Malwarebytes, the full version which I run once a week.  Norton 360 runs twice a week.

 

I need some good advice.

 

Thanks
