"Deny change" option greyed out after BHO shows up uninvited

[joestrike]

Okay, I'm a first time poster, came here for help with something that just happened a minute ago:

My computer stopped dead, went black so I started it up again. When it came back there was a Spybot-S&D box onscreen:

"Spybot S&D has detected an important registry entry that has been changed

Category: Browser Helper Object
Change: Value detected

Entry: {F9E4A054-E981-4BC3-83A3-76A1AE736170... [numbers appear to continue inside the box]

[greyed out] Old data:
[greyed out] New data:

[checkbox] Remember this decision.
[Allow change] [?] [Info] and the final box which is greyed out: [Deny change]

Not only is this last option greyed out, there's no 'X' in the upper right corner of the Spybot S&D box to cancel the box.

Anybody have any suggestions? I"m sure as hell not going to click on "Allow Change," at least not right now.

UPDATE:

My son just came over, opened the Task Manager and did an "End Process" that got rid of the Spybot S&D box that wouldn't close. Am I out of the woods with this thing now?

Thanx much!
