>>Just curious, what version of Norton Internet Security?

>>I tend to have the same opinion on this issue, after coming very close to having to wipe the hard drive on my laptop two or three years ago due to a failed update of Norton SystemWorks. After several years of swearing by (not at) Norton products all the way back to the DOS days, I did not change my opinion casually, but that experience did it for me. In any case, the 2009 version of Norton Internet Security is supposed to be faster and more lightweight. I'm considering it for a new Vista laptop, but I don't know if it's any less intrusive than earlier versions.

FWIW I've been running ForeFront for about a week, and I'm very happy with it so far.

My Vista laptop seems to have gained about 50% more speed compared to running AVG 7.5.
