The programs are proably in your startup. The easiest way is gonna be crossrefrece google with the process you killed and find out what programs they are. If you already know, then just unistall them. If for some reason you wish to keep them. Most windows machines allow acces to the startup via, start run msconfig. It is self explanitory once you get there. Also depending on your knowledge, it wouldn't hurt to take a look at the registry. access it from the same start run point. just type regedit .Correct me I'm wrong but it is. Hkey_local_machine/software/microsoft/windows/current_version/RUN. These are also files that startup, when the explorer shell loads. Now I recommend you export this run folder and save it somewhere. File to export and then type a file name, and then save it. Now if you screw it you can simply merge this entry back into your registry. There are other ways to restore the registry. However if you are gonna hack at a line at a time. Then this method should work fine.
