Sooner or later your free trial of the Google Pack Norton Anti-viurs 2005 will be running out.
In anticipation of this, I can recommend you switch to an Open Source solution.
The application is call AVG-Free edition, which provides a real-time scanning utility with updates for Windows and Linux users.
In addition to this AVG-Free provide an anit-spyware application. This provides free updates, the free version provides real-time scanning for 30days and then defaults to free updates and manual scans there after.
