MALWARE ATTACK : GOOGLE IS A RETARD

My Gerrardart site has had some problems recently. Someone or something has been targeting my site and adding malware, bastards . So now when you search for gerrardart in google it says ' 'This site may harm your computer'. I have recently wiped clean the old site and all the files and completely redone the website from scratch. SO , all new clean Gerrardart.com!. Unfortunatey google search is still registering my old site and disclaiming 'This site may harm your computer'. Plus Firefox uses data from google and determines if a site is safe or not. Not much I can do about that Im afraid untill google catches up on itself and sees the new site, whenever that may be.
