My computer has viruses and I am a victim of identity theft. I tried installing McAfee but it won't allow full installation without remving Norton Internet security first from my computer. I tried going to add/remove programs and it won't allow me to. Can you help

Here's the lnk for the Uninstall Tool from Symantec. (Norton)
Download and run the Norton Removal Tool (http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2005033108162039)
It should do the trick.
Let me know if you still have problems.

Hope this helps.
