Users of Avast-owned security application CCleaner for Windows have been advised to update their software immediately, after researchers discovered criminal hackers had installed a backdoor in the tool.

It's unclear just who was behind the attacks. Yung said the company wouldn't speculate on how the attack happened or possible perpetrators. For now, any concerned users should head to the Piriform website to download the latest software.

If the operating system itself would allow good cleanups, software like this would not even be needed.
