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
It should do the trick.
Let me know if you still have problems.

Hope this helps.
