Which put them in class with such esteemed companies as McAfee and EA Games, both who also need cleaners to clean up crap after install often enough to have cleaners in their soft/malware.
I wish I knew this existed the other day, I spent about 10 minutes tracing all the crapware creative cloud had installed onto my macbook and deleted it. Some of it was using 5% cpu occationally, to do what?
Last time I needed it even their cleanup tool didn't manage to completely remove everything. We ended up reinstalling the whole machine to fix it.
