Use the Kido Killer to remove Conficker from your PCs:

http://support.kaspersky.com/faq?chapter=207800963&print=true&qid=208279973

Search for 'To remove the virus locally' and download the zip file and run the tool within. It will remove Conficker (also called as Kido by Kaspersky) from the machine.

Make sure that your PC's are completely patched with the required Windows Update:

Hope it helps.
