On July 29, we published a blog titled “PUP Friday: Cleaning up with 5 star awards”, taking a look at a registry cleaner called RegCleanPro made by Systweak. We detect the file in question as a PUP, and covered it as part of our regular PUP Friday series. The makers of Systweak software posted both to our blog comments (with no response to my reply, at time of writing) and also posted a blog on their website titled “How Malwarebytes Got It All Wrong with RegClean Pro”.
Below is a reply to both the comments made to our blog and their own post. The comments from their blog are numbered and in bold, green text, with our responses to each point underneath.
