How can I get rid of McAfee SiteAdvisor that has installed itself on my Firefox browser screen?

An uninvited McAfee message flashed up on my screen when I was on the net and I mistakenly clicked a button that installed the McAfee SiteAdvisor on my browser screen. I have tried to uninstall the McAfee program and to delete the files that McAfee has stored on my computer, but when I try to delete those files a box comes up saying that they cannot be deleted because they are either write protected or in use by another program. I do not want to have to read a McAfee SiteAdvisor bright green notice on the bottom corner of my computer screen every time I use Firefox. Does anyone know how to get rid of the files McAfee has stored on my computer? Thank you.

I used to have McAfee site advisor on one machine last year. I do not remember major problems un-installing it presumably it uninstalled easily from the Windows XP control panel -> remove programs.

I also seem to recall it created a long list of files possibly totalling in the GB range of memory use, if I remember correctly I had no problems in removing them.

If you have McAfee security products on your computer you may need to be careful about what is uninstalled.
