Found this software on the cover CD of PC Answers October 2007. It offers 180 day of realtime protection as compared to the free version of Lavasoft Ad-Aware 2007. Since prevention is better than cure, I decided to install on my laptop running Windows XP SP2.
Installation was smooth but unable to register the license automatically. Had to input the serial number given manually and select upgrade license from SE to Plus before it can be registered and the realtime protection can be turned on.
Also, you have to select the setting to load Ad-watch at startup. This is the component for the realtime protection otherwise your computer will not be protected. The browser setting only supports IE. You can set the scheduler to perform Web update for the definitions file on a daily basis.
