Here's something puzzling, using NIS 2009.
I'm assuming these are false alerts, but if you do a search for a site on google and click on the link all is usually well but click on google's cached link and Norton flags an alert.
Even does it for these forums - entered community.norton.com into google, clicked on the cached link and I get the following warning:
Summary

I'm no computer expert but I'm guessing google's adding something innocent that norton sees as a false threat ??
