Be ashamed of yourself.
Bundling your software with other software that does not ask for consent to install it is not a good install practice. It is not a good way to grow your user base, and it's only slightly less shady than the viruses and malware that yours supposedly removes.
Look yourself in the eye and consider what you're doing to people's computers. If your software was good, people would use it and recommend it to others. Not be hit by it in the digital equivalent of a drive-by shooting.
