I's downloading to take a look, but I'm not hopeful. I always refused to use Norton, it was such a bloat, it was worse than getting a virus and having to root it out.
[Edit] Changed my mind about getting this. 172Mb, WAY too big for what we need.
Mostly, if I am feeling vulnerable, I'll use ClamXAV.
Also free is Sophos and Avast. Sophos wasnt bad, but I ended up uninstalling it. Avast I've never tried.
[Edit #2] About to try Avast which is only 56Mb on the d/l
