1. Enable a Firewall
Make sure you have a firewall activated to help protect your computer against infection before you take other steps. If your computer has been infected, activating firewall software will help limit the effects of the worm on your computer.

If your computer is rebooting repeatedly, disconnect from the Internet before you enable your firewall. To disconnect your computer from the Internet:
- Broadband connection users: Locate the telephone cable that runs from your external DSL or cable modem and unplug that cable either from the modem or from the telephone jack.
- Dial-up connection users: Locate the telephone cable that runs from the modem inside your computer to your telephone jack and unplug that cable either from the telephone jack or from your computer.
Follow the instructions provided for your operating system, and then reconnect to the Internet.
