I uninstalled all the seperate apps and deleted HKEY_LOCAL_MACHINE/SOFTWARE/AHEAD. Thanks for the replies. If I can't get it figured out it's no big deal, just a minor annoyance.
I uninstalled Nero and "Nero Burning Rom" still shows up on my applications list. I'm pretty inexperienced with registry editing but I deleted the registry entry for Ahead. Was that a mistake? Nero still shows up on my apps list.
I noticed that when I click on the applications tab of CCleaner EZ Antivirus is listed. I don't have EZ antivirus and have never used it. Can anyone tell me why it shows up?
