I'm not familiar with TSP - what's the full name and is it provided by Dell?
OOPS!- Sorry it should have been TIS (Total Internet Security).
It must be something renamed by Dell then as we only have VirusScan Plus, Total Protection, Internet Security or All Access.
It's quite possible that the uninstaller is wrecked because of malware. See the last link in my signature below for some suggestions.
If the latest version of MCPR doesn't work - and I stress you must always use the latest version, from HERE, and sometimes it needs to be run more than once, rebooting each time, then you would have to remove the software the long and involved registry way.
Go to Start/Run and enter regedit and click OK. In Windows 8 it's easiest just to click the Windows key + R simultaneously.
A page should open with the top left hand corner looking something like this:
if for some reason it's expanded, collapse it and then highlight My Computer (Computer in Vista/Windows 7/8).
Go to File tab and click "Export" and send all of the registry to your desktop. This is in case something goes wrong. It can then be rebuilt by simply right-clicking that desktop item and selecting Merge.
Now click the Edit tab and then "Find". Enter "McAfee" (minus the "") then click "Find next" (or hit the enter key).
Whatever is found, right-click and delete.
Hit your F3 key for the next instance and keep going until all entries are gone. It can take a long time if a lot of McAfee components were oroginally installed and the MCPR removal tool (Useful Links at top of this page) didn't work for some reason.
If one says it can't be deleted this is where it gets complicated. You have to then find which key on the left column pertains to it and right-click/Properties/Permissions and give yourself permission.
