Thanks for the info....deleting Crap Cleaner.
5.30.6065 will still be fine, it was made long before this, and with auto update off (which everything should be on, except flash and java) Avast won't get their hands on it.
Looks like your fears were founded, Avast put malware in CCleaner for a month, and yet another glowing example of WHY FORCED AUTOMATIC UPDATES ARE A BAD IDEA! Thankfully CCleaner Free Edition are manual updates, and if most people are like me, they don't update it.
Cisco’s Talos Intelligence security research group found that CCleaner, a popular piece of software that allows users to do routine maintenance on their Windows PCs, has been distributing malware along with its installation file for almost a month. Piriform was the previous owner of CCleaner, but the company has recently been acquired by antivirus maker Avast, which makes the whole situation quite ironic.
CCleaner’s Suspicious Activity
On September 13, Talos was conducting some beta testing for its new exploit detection technology when it noticed that CCleaner 5.33 (the latest version at the time) was being flagged by the new software.
The Talos team further analyzed the CCleaner file, and although the file was correctly signed by the vendor, CCleaner was not the only application being downloaded on users’ systems. The 32-bit binary of CCleaner 5.33 also included a malicious payload with a connection to a hardcoded command and control server.
The affected version of CCleaner (v5.33) was released on August 15, which gave the malware almost a month to infect CCleaner users. Version 5.34 came out on September 12, the same day the CCleaner devs found the malware themselves, and it didn’t have the malware bundled with it.
