Help with Add or Remove Programs and mtoolkit listings I just found

Dell Inspiron 6000, Running Windows XP. Computer has worked perfectly all along. Today I noticed that the remove button from Add and Remove Programs was missing. Then I noticed that there are tons of new programs listed - looks like many of them are mtoolkit files according to some research I've done. Some forums say they are unique to Dell some say they are related to wireless. I need to know what these are and if they've affected my ability to remove programs. They were not there recently. Can I delete them all and if so, how? They don't show up in a search and there is no remove function.
