Just got new computer and brought Norton 2005 and its giving me nothing but hassle!

It worked fine on my old computer set up????

xp very slow to shut down and sometimes wont at all and have to do it manually....

The main prop is though it won’t let me use any file sharing programs or skype!
I’ve set it up all properly in "Norton set up manually" but makes no difference, I think I hate it!!!!!

Is there any way round these props apart from binning Norton?

What internet security have you got which you can recommend??
