Have just downloaded the latest update versions of Norton Anti-virus and Spysweeper.
Each time I access the web, a Zone Alarm Pro Alert appears.
"Commonn Client CC App and components are trying to act as a server.
Apllication: ccApp.exe Components: Click for Details
More information available.
One or more components used by this process have changed or are new. Unless you have recently upgraded or installed, you may want to check the authenticity of these components by clicking the details button."
Clicking the Details button has proved inconclusive.
I have had problems with malicious items previously so am wary of further corruption and hence I have been 'denying' access.
