A couple evenings ago a site I recently joined got hacked. They put some kind of executable malware on the front page which caused the site to be reported as an "attack site" so it won't come up in Firefox unless you disable security, and when I went there in IE well, my anti-virus program hopefully blocked a couple viruses.
She had to go in and fix everything and change all her passwords and then notify Google so they can rescan the site and remove the block, but due to caching and other things it can be many days before people can navigate to her site normally again. WTH is with people?? -_-
