With three antivirus at the same time... With Norton!...
I really suggest that you backup your data and start all over again.
Try avast!  

P.S. If you search the forums you will find a lot of information of how to uninstall Norton

I had this problem: it happen every times McAfee antivirus services starts (at Windows boot or after a McAfee update)

try uninstalling Mcafee there will not be this message anymore.

Btw when you unistall Mcafee it create an exe file which tries to log on to the internet: for example  2004212194848_mcinfo.exe, 2004212194851_mcappins.exe and 2004212194848_MCINFO.-355A3F32.pf

I'm on WinXP and had McAfee Antivirus.
