Unable to reinstall AVG Internet Security

I used the AVG uninstall tool as was having problems with AVG Internet Security.
Having unstalled all things AVG I tried to reinstall and the message I received was that AVG had already been installed. I no longer have an icon so please advise what to do. I have paid for 2 years subscription.
