I have uninstalled mcafee.

Every so often it still pops up and asks me if i want to install again, or would I like to install some sort of browser link checker....

Delete the Program Files folder. Go to %appdata% and check if there are some folders there (including hidden ones). Delete them too. Check the temp folder. Find out how to clean your registry (not recommending any particular software, but it exists).
