Piriform, a subsidiary of Avast, has released CCleaner 5.34 and has pushed v1.07.3214 to CCleaner Cloud users. These versions do not contain the Floxif malware found in the 32-bit versions of CCleaner 5.33.6162 and CCleaner Cloud 1.07.3191. Floxif malware collects information from the victim's system and can download additional malware to the system.
US-CERT encourages users and administrators to review the Piriform Security Notification and apply the necessary update.
