Bongo if you like norton then you will LOVE Spybot - Search & Destroy.
You can make it so it auto runs and when you get back you can delete any that you find or you can keep them and make it so it doesn't find that again so you don't have to see that one that you want to keep again.
It has a great UI (User Interface) and is really easy to navigate around and manipulate how it works.
Again I would recormend you ALL to get the following programs...
Spyware Blaster - Spyware Deleter (blaster)
Spybot - Search & Destroy
You can find them both on www.majorgeeks.com
