CCleaner was compromised by hackers
– CCleaner, the popular PC cleaning tool from Piriform and distributed by Avast, was compromised by hackers. This resulted in the install file being modified, added to their servers, and then downloaded by millions of unsuspecting customers. Piriform released a blog post today detailing the incident. They found the malicious code in the program while doing an audit. When installed to the computer, the program then downloads an additional malicious package which transmits PC data and can provide remote control to the PC.
What to do
– If you have installed CCleaner between August 2017 and today, please uninstall CCleaner to ensure the program is gone and then go to http://www.piriform.com/ccleaner to download the program again. We highly suggest you run a full scan with your anti-virus / anti-spyware program(s) as soon as possible.
