CCleaner has been compromised!
If you use CCleaner, you should uninstall it and install a fresh copy of it immediately.
Hackers broke into British company Piriform’s free software for optimizing computer performance last month and installed tools that could have allowed them to take control of tens of millions of devices, the company and independent researchers said on Monday.
The malicious program was slipped into legitimate software called CCleaner, which is downloaded for personal computers and Android phones as often as 5 million times a week. It cleans up junk programmes and advertising cookies to speed up devices.
