"If you have downloaded or updated CCleaner application on your computer between August 15 and September 12 of this year from its official website, then pay attention—your computer has been compromised.

Security researchers from Cisco Talos discovered that the download servers used by Avast to let users download the application were compromised by some unknown hackers, who replaced the original version of the software with the malicious one and distributed it to millions of users for around a month."
