Internet connection problems

I have installed the internet security program, but when I try to get the virus definitions it says that my acer aspire one isn’t connected to the internet while it is.

I am using an acer aspire one netbook and have a wireless internet connection at home, all other internet programs are workinging fine just comodo wont recognise that I’m connected. What do I need to do to let it know that I’m connected?

What version of CIS are you using?
