Hmm, erroneous programs... you mean like malware or PUPware? Try running Malwarebytes.
If you need to uninstall a program that doesn't uninstall there are some extra strength uninstallers... but certain situations don't lend themselves well to uninstallations.
Security Task Manager still works well also especially on running programs you want to get rid of ... Right click and remove will kill the task and quarantine the files on disk it came from.
Try to dig up some more details on exactly what you think the programs are... we might be able to do more than offer a Wild Donkeys Guess.
