Sweet, but if the website is based on your IP (most sites are) you got to have a damn good anti-virus since I do know how to shut down websites from my own PC (Don't worry I won't do it to you) and if they don't have anti-virus, the attack will go on and temporarily shut the website down.
If you have good anti-virus however, the attacks will be blocked and your site will remain safe.
