I think he is referring to this product : WEBROOT® ANTIVIRUS WITH SPY SWEEPER
Mi7892 , I have tested Webroot in the past and I must say that I wasn't very impressed , if you want to spend some money and buy a Webroot product, I would suggest another acquisition,like Prevex or just wait for the release of Webroot SecureAnywhere.
Their are other good paid options if you chose this road, however real-time protection isn't everything so I would like to suggest to you to start a thread in our "Security Configuration Wizard" forum , and we will help you with your PC security config.
