Argh! Kids' laptop riddled with spyware!

I downloaded the current beta version of MS' new Anti-SpyWare tool yesterday and installed it on my kids' laptop.  When I ran the scan, I found something like 16 different types of SpyWare installed.  The trigger was starting up IE on the machine and being greeted with something called the "Megasearch" tool bar!

I can say that the new Anti-SpyWare tool seems to do a really good job.  Of course with SpyWare, you don't know what you don't know.  There could be another dozen SpyWare packages installed on my system that the tool didn't detect, but at least I know I got some.  Oh well, what are you going to do?...
