Trojan.Vundo - Further Action?

Hello,

 

NIS 2009 has found and quarantined Trojan.Vundo indicating that no further action is required.

I restarted my computer (Windows XP SP3) and everything appears to be working fine.

Is there anything else I should do?

I'm not very computer savvy and viruses scare the bejeezus out of me.

I've used Norton's Premium removal service in the past with mostly positive results. Should I do this again to be safe?

 

Thanks.
