Yes it was gator.com. Take a look at this
article
If you do a Google search you can probably find out more information on them. Anyway what happens is that you will go to a website that has an agreement with them and a pop-up box will appear saying in order to view this site you need to run and install an applet from gator.com. If you agree to this and actually run it..BAM your PC is now full of spyware. If you read the popup box it actually contains the user agreement that tells you what you are about to do and that by clicking ok you are fine with it.
These guys are all tricky bastards and I wish that this type of decit was not allowed. The only thing I can say is that you need to be very very careful about what you allow to be downloaded on your PC.
