You could be infected

If you have CCleaner 5.33 installed, you could be one of the millions of people that still have or had a version that was compromised.

Security researchers at Cisco Talos discovered that download servers used by the company that owns CCleaner, Avast, were compromised to distribute malware inside CCleaner. The Talos team reported, “For a period of time, the legitimate signed version of CCleaner 5.33 being distributed by Avast also contained a multi-stage malware payload that rode on top of the installation of CCleaner.”

Over 2.27 million users were affected by the malware attack, and Avast Piriform believes the company was able to prevent the exploit from harming customers. It did, however, commandeer computers to participate as part of a botnet that attacked internal networks at large companies such as Google, Microsoft, and Samsung.  Other targetted companies were Sony, HTC, VMWare, Intel. Cisco, Vodafone, Linksys, Epsom. MSI, Dlink, and some Asian companies.

A botnet uses infected computers as zombies, stealing their resources to attack or spam a target without the owner’s knowledge. Signs that your computer resources are being used are; slow internet speeds on your computer, pages not responding, programs not opening, freezing, slow startup or shutdown.
