CCleaner Installs May Contain Malware

– a press release

“The compromised versions of the software are CCleaner 5.33.6162 and CCleaner Cloud 1.07.3191.”

For Immediate Release – September 19, 2017

Muncie, Ind. – CCleaner, a free software tool designed to optimize system performance on Windows machines, has recently been linked to malware. According to a blog post from the company which makes the CCleaner tool, recent installations of the popular computer software likely opened the door for unauthorized data mining. This specific malware did not adversely affect system performance, but instead acted as a data-harvesting tool to relay information about end-users machines to a remote third-party server.

The compromised versions of the software are CCleaner 5.33.6162 and CCleaner Cloud 1.07.3191.

Avast, the company behind CCleaner, has reported that the remote server has officially been shut down in cooperation with U.S. law enforcement. Affected users are encouraged to uninstall or upgrade to the most recent version of CCleaner — version 5.34. And for those with auto-updates enabled, this step has already been completed.

If you have any questions about CCleaner or computer optimization, please contact Deltec Solutions.
