Open Source license that prevents from bundling with adware?

I wrote a small tool I published on my blog. I did not even think about the license, just put the binaries there for everyone to download. Now I am thinking about making it open source (BSD or GPL) but have already seen that my tool was available for download on other sites that bundle it with their own installer which also installs Browser-Addons aka. Adware. (we all know this crap)

Is there an open source license that forbids this but still allows the usage as open source? If not? May the GPL be modified to fit these conditions?
