Woke up yesterday to find Google malware notices on my TGP.
Big thanks to my host
Colo-Cation and cd34
aka Sparky for quickly helping in finding and removing the malware from my banners.
OpenX was hacked and malware code as appended to my banners.
OpenX has been upgraded to the latest version so hopefully this won't happen again.
Naturally all this had to happened on one of the few days that I was away from the computer spending the day on an island.
Thanks for everyone that sent me a heads up on this.
All should be well now.
