How many viruses or ...?

Out of idle curiosity, how many viruses or threats have you had to actually work to remove from your systems over the last five years using Norton products?  I'm not talking about those of you who go to websites or download things just to see if you get infected; I'm just talking normal, everyday computer use.

 

I've used Norton Internet Security since 1999 give or take.  I've had one Smitfraud variant that was stopped but left the nasty little blinking balloon on my desktop.  I also just recently had to remove parts of Brisv A.  Pretty darn good considering I had two teenage boys during most of that time, with a fondness for music and porn.

 

How does Norton stack up for others on average use?
