In a press release on Monday, Piriform’s Paul Yung, VP of Products revealed that the company spotted a security breach in CCleaner 5.33.6162 and CCleaner Cloud 32Bit Version. CCleaner is a popular  optimization tool for Windows and Android operating system.

Yung said that the version was compromised by some attackers before its release, who managed to attach some malware to the setup. Sad to say, this was discovered by Avast who happens to to be their parent company.

What does the malware do?

It gathers information like your IP address, computer name, a list of installed software on your computer, a list of active software and a list of network adapters and sends it to a third-party computer server. Your credit card numbers, social security number and the like seem to be safe.

Here are other data it collects

  • Name of the computer
  • List of installed software, including Windows updates
  • List of running processes
  • MAC addresses of first three network adapters
  • Additional information whether the process is running with administrator privileges, whether it is a 64-bit system, etc.

Who was infected?

According to Piriform, around 3 percent — roughly 2.27 million computers — used the infected software. Specifically, computers running 32-bit Windows 10. If that applies to you, don’t panic. The company believes that they were able to disarm the malware before any harm was done.

 

How do I know if I have the corrupted version?

The versions that were affected are CCleaner v5.33.6162 or CCleaner Cloud v1.07.3191 for 32-bit Windows PCs. The Android version for phones doesn’t seem to be affected.

If you’ve updated your software since September 12, you should be OK. This is when the new, uncorrupted version was released. Also, if you have the Cloud version, it should have automatically updated itself by now to the clean version.

I don’t use the cloud version. What should I do?

CCleaner v5.33.6162 does not update on its own, so if you use the non-cloud version you may have the corrupted software. Piriform recommends deleting your current version and downloading a clean version from its website.

After you have your new software downloaded, run a check on your system using malware protection software to be sure that CCleaner didn’t leave any nasty invaders behind.
