Just got hacker attacked, my data is bad


Just got attacked by a hacker, long story short, what is the best way to remove all analytic data from my database so that it will remove the attack as it’s a hacker hitting one page that does not exist (so all data is a 404 eror page) a few hundred times, I want to get rid of this data in my logs so that it does not appear anymore?

Thanks all, great job so far with Piwik everyone, it’s awesome!
