There has been quite a bit of press coverage today about our announcement that the Piriform CCleaner product was illegally modified during the build process to include a backdoor component. Our first priority is our commitment to the safety and security of our millions of users, and supporting our new partner Piriform as they manage this situation. We understand that given the late disclosure of the massive Equifax data breach 10 days ago, consumers and media are very sensitive, as they should be. As such, as soon as we became aware of this issue, we engaged and solved it. Within approximately 72 hours of discovery, the issue was resolved by Avast with no known harm to our Piriform customers. The purpose of this article is to clarify what actually happened, correct some misleading information that is currently circulating, recap what actions Avast took, and outline next steps.
