LOL, you are going from one terrible product to another one. Norton and McAfee are core hogs, use a lot of resources and will slow your system to a crawl, especially if you let it expire. Why would you want something on your system that is so difficult to uninstall? Give em the boot. Try one of the FREE Antivirus programs such as AVG, AVAST or Microsoft Security Essentials.
Dell did not create this monster, your third party software is the culprit and they just don't deal with it if it's not their product.
Anyway if you tried the normal uninstall by clicking Start/Programs and opening the McAfee Folder and clicking uninstall and you're getting the BSOD, maybe try uninstalling it in Safe Mode With Networking.
Turn off the computer, then hit the power button to turn itback on and immediately start hitting the F8 key repeatedly until you see SAFEMODE. Take the Safe Mode With Networking option and let it boot up. Safe Mode will lookdifferent to you, the screen will be darker and the icons bigger, this isnormal.You can also go into the Control Panel and Uninstall the Program. Click Start/Control Panel look for Program and Features or Programs or Uninstall.
You can try the McAfee Removal Tool. Download and Install it, then run it. The link is below:http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe
