The Registry feature acts in the same fashion, letting you check off on the options you'd like to scan for issues. By selecting the appropriate check boxes, we were able to clean our temporary Internet files, cookies, history, and cache in both Internet Explorer and Firefox at the same time, as well as empty our Recycle Bin and rid our computer of Windows log files. The program works by first analyzing your system and then running the cleaner itself.
We started with the Cleaner first, which breaks down your cleaning options into two tabs: Windows and Applications. Its four features - Cleaner, Registry, Tools, and Options - are prominently displayed on the left side of the window. CCleaner is one of the better ones for its ease of use and powerful cleaning capabilities.ĬCleaner's simple and intuitive layout will appeal to users of all skill levels. Thankfully, there are myriad freeware cleaners out there that help keep your system in check. Some of these trackers are useful, while others can be potentially intrusive.

“We estimate that 2.27 million users had the affected software installed on 32-bit Windows machines,” she further added.Nowadays, cookies, temporary files, and various other means of tracking your Web footprint are par for the course. Piriform was the company that Avast recently acquired and was the original company who developed the CCleaner software application.Ī spokeswoman for security giant Avast, which acquired the UK-based company back in July, told TechCrunch: “We believe that these users are safe now as our investigation indicates we were able to disarm the threat before it was able to do any harm.” This version was signed using a valid certificate that was issued to Piriform Ltd by Symantec and is valid through.
The version containing the malicious payload (5.33) was being distributed between these dates.
#CCLEANER CLOUD LOGO DOWNLOAD#
In reviewing the Version History page on the CCleaner download site, it appears that the affected version (5.33) was released on August 15, 2017. We confirmed that this malicious version of CCleaner was being hosted directly on CCleaner’s download server as recently as September 11, 2017. During the installation of CCleaner 5.33, the 32-bit CCleaner binary that was included also contained a malicious payload that featured a Domain Generation Algorithm (DGA) as well as hardcoded Command and Control (C2) functionality. We identified that even though the downloaded installation executable was signed using a valid digital signature issued to Piriform, CCleaner was not the only application that came with the download. Talos began initial analysis to determine what was causing this technology to flag CCleaner. Upon closer inspection, the executable in question was the installer for CCleaner v5.33, which was being delivered to endpoints by the legitimate CCleaner download servers. On Septemwhile conducting customer beta testing of our new exploit detection technology, Cisco Talos identified a specific executable which was triggering our advanced malware protection systems.
#CCLEANER CLOUD LOGO UPGRADE#
The company is urging users to upgrade to version 5.34 or higher (which it says is available for download here). The affected versions of the software are CCleaner and CCleaner Cloud. The security team at Cisco Talos discovered that download servers used by CCleaners had been compromised to distribute malware inside CCleaner.
