I don't know that P5 has problems with Norton Anti-Virus or Roxio's CD stuff for sure, but the linked thread discusses the possibility, particularly with people running Win ME. And if you search the forum for Roxio, you will turn up other threads noting that a number of apps, including various anti-virus apps, AOL, and EZ CD Creator overwrite some of the standard MS system DLLs and drivers, which could be a source of some people's problems (and which, incidentally, would not be solved just by turning the app off during install). My guess would be that an anti-virus app by itself would generally not conflict with P5, because so many PCs come with one from the factory and any such conflict would also hamper CL's efforts for Content Paradise. But I have no definitive opinion on it because there are so many variables from system to system. It's a problem endemic to the software biz as it stands today. One of the other threads notes that a fair amount of this type of problem would have been solved if MS had structured its OSs differently (though it ocurs to me that if MS tried to make it difficult to change DLLs, some would have seen it as more evidence of their attemots to deter companies from developing apps that compete with MS apps).
