Norton 360 verdict not in yet – don’t be a guinea pig
Norton has recently released a new version called Norton 360. Symantec claims that they have scrapped 80+ percent of their old code and the 360 version is a totally new program.
I have only seen it installed on one computer so far and I couldn't really see if it was any faster or slower than previous versions. Since the system I saw it on was also running Windows Vista, I couldn't tell if the sluggishness of the computer was caused by Norton or Vista.
I can say that I have Vista running on a very similar machine as the one I saw running 360 and it didn't seem any slower.
