Windows 7 Understanding Quarantined Spyware Keyloggers: Are Keystrokes Still Being Logged?

[Heaven or Hell]

My Symantec AV has quarantined a file that was a spyware.keylogger kind of malicious file.

I know quarantining means to lock up a malicious threat so it doesn't spread, but, in this particular case, does quarantining mean its stopping it from doing what its name implies? Logging keystrokes...that's like people getting you user and password info to various sites.

Just wondering if quarantining will prevent a spyware.keylogger file from logging keystrokes (or prevent it from doing anything for that matter).

Thanks...
