Well, yes and no.

When HE logged in, Norton could have snipped the bastard and all is well.
Or, the virus has more than one copy of itself. And even then, Norton should have nipped it.

My guess the virus created its own "instruction" and it was looking for her everytime since she was the initial infection and that's how Norton was able to nab it when he logged in.

I'd download AVG and run that too. Besides running a full system scan with Norton again. Reboot, then run it again. Odds are its gone.

But with the AVG, just disable, not delete, norton and run AVG. Do a full system scan. See if it finds anything.

Might not be a bad idea too to run Lavasoft's AdAware on full system scan and delete EVERYTHING it finds. Because the virus may be gone, but it might have left some marketing bullshit behind that may make it easier to infect again.
