Our blog was Shanghied by a gadget

OK, here's a new one. Our blog was hijacked so that whenever one of us, or anyone else logged onto it you would be directed to another site, which was a blank white screen. I looked up the site on Google help and found that it was a problem with certain gadgets. I removed the weather gadget at the bottom of the page from Weather.com and the problem disappeared. So we are now back to normal. Computers are your friend....computers are your friend....
