You cannot shutt it of like that, you must patch your hostfile which is located normaly here:C:\WINDOWS\system32\drivers\etc\hosts. To edit the host file you open it with notpad...Then you add all these lines here to the hosts file:

127.0.0.1 ad.doubleclick.net #ban this common popup
127.0.0.1 media.fastclick.net #ban this common popup
127.0.0.1 sms.ac #ban this common hijacker popup


Then exit the hosts file, and click yes to save the changed hosts file!
I have tried it out and it's working...BearShare should not run when you do that ;-))
