Is there any other scanning or anything I can do to be sure this is ok?
No, Carol, unless you plan on doing a clean install.
How many ways I can block/disable/even root out or remove windows messenger ?
I know a few but it has been known to come back if I don't get them all.
(Scotty works great. I think I'll get the deluxe one for my computer)
Carol, this is a Windows 7 computer. The Windows Messenger Service was on Windows XP and Windows 2000. It was removed from Windows Vista and Windows 7.
If you are referring to the Windows Live Essentials programs, including Windows Live Messenger, that is up to the owner whether he wants it installed.
