How do I get rid of the mackeeper popup from http://mackeeperapp2.mackeeper.com? This is not the zeobit version. Adware scanner doesn't find anything. It pops up (or under) whenever I close Safari.

I have Mac OS X 10.7.5.

It is advertising MacKeeper and I would like it to bug off.
Add the following lines to /etc/hosts and mackeeper goes away forever:

127.0.0.1   mackeeper.com
127.0.0.1   www.mackeeper.com
127.0.0.1   mackeeperapp.zeobit.com
127.0.0.1   mackeeperapp.mackeeper.com
127.0.0.1   mackeeperapp2.mackeeper.com
