possible two IE's

I have internet explore and on my desktop it says IE2? how do i find out where the other IE is and what do i do to delete it? When i called dell a few days ago and asked a dell person how to set back my homepage i got charged 39 bucks for that it makes me so angry i should of waited and asked here how to change it. also i downloaded malware bytes per buggbatter and it is very nice thanks it says my system is fine but on the logs that it saved when i run scans there were some registry changes and it said infected yet the files said that they are cleaned. I did notice today tho when i ran a scan that when i look at the log files they say registry keys infected and in quotes under that it says no malicous items detected? why then would it say registry keys infected for? one more thing every time i down load something or delete something i get a message stating that my reg key will change and it will ask me if i want it to i always say ok cuz i believe that it must need the new reg key to make what ever program i downloaded to run i think this is happening because i have spybot on my windows xp desktop i wonder if it is anything to worry about? when i click yes change it nothing seems wrong so it must be spybot doing this it does say registry change spybot then when i do click yes it'll have a window in the lower right corner of my screen letting me know that the user allowed the registry change
