Hackers Infected CCleaner’s 32-Bit App, Here’s How To Fix It

This morning, Piriform, developer of PC maintenance tool CCleaner, announced it was breached by hackers who infected an estimated two million users with malware. Prifirom says the incident has since been resolved, but encourages users to update the software to prevent further compromises.

The malware, discovered by security researchers at Cisco Talos, accompanied downloads of certain versions of CCleaner. Luckily, not every CCleaner user is affected by the malware breach. “This compromise only affected customers with the 32-bit version of the v5.33.6162 of CCleaner and the v1.07.3191 of CCleaner Cloud,” said the company in a statement addressing the breach. “No other Piriform or CCleaner products were affected.”

We asked Piriform’s parent company, Avast, what users should do if they find themselves with an infected version of the popular maintenance app.

They said updating CCleaner to its latest version, 5.34, removes the offending malware, while users of CCleaner Cloud should already have received a software update addressing the issue. If you’re still worried, or want to ensure you’ve got the most recent version of CCleaner, you can reach their download page here and do it yourself.
