Computer help: I have an administrator account on my Vista machine, but it tells me I don't

[Rabrrrrrr]

That is, the account that I use when I use Vista is an administrator account.

BUT - spybot has found a couple malwares on the system. I tell it to go ahead and fix them, but then am told I need to use an administrator account to clean a few of them out. It cleaned out some, but I have three left that apparently need administrator approval to clean out.

I am using an administrator account.

I even created a new administrator account and ran the program under that one, and got the same message.

Windows admits that both accounts are administrators - why does it not communicate such info to spybot?

:argh:
