It recently became clear that version 5.33 of the popular clean-up tool, CCleaner, was infected with the Malware dubbed “Floxif”. Using Lansweeper you can scan your Windows computers to find out which computers are safe, are currently still infected or were infected. To diagnose this as accurately as possible we’ll be scanning for multiple things. After following the steps below you can find out whether any scanned computer in your environment was affected:
  • In the web console go to ScanningFile & Registry Scanning
  • Click the Add File Scan button and enter the file path below
    CCleaner 1
  • Click the Add Registry Scan button, select HKEY_LOCAL_MACHINE as rootkey enter SOFTWAREPiriformAgomo as regpath and MUID as valuename
