This was most likely not a java script, but rather a devious way of using the built in possibility to send system messages in Windows. It had nothing to do with the browser or something planted in your computer. Ad-Aware is a great product, but it will not help you in this case. A company called Direct Advertiser has "discovered" this seldomly used feature in Windows and sells an application that makes it possible to send a system message to a range of IP numbers. You can check out all this at www.directadvertiser.com. They are actually nice enough to provide info on how to disable this feature in Windows and make it impossible to send these messages to you. Using this feature for advertising is really an all time low in the history of spamming. Any company that does it will immediatley be frowned upon. I can't believe that Direct Advertiser will be able to keep their product on the market, people will be after them with a blow torch... And when everyone disabled this feature in Windows, the product will become useless anyway...
