The Hun,
There is a wealth of info on this dire issue at
www.gethighforums.com , where you can find a whole new forum dedicted to it: ScumWare - The Net Fights Back!
Jim of jimworld.com/gethighforums.com is heading a campaign against these new scams. And he has opened an official site to fight them, mentioned in a post above:
www.scumware.com . It's well worth a visit.
There are already a couple of JavaScripts that disable OpenText and Surf+, and more seem to be on their way
Finally, you can help in the fight by signing the petition at
