Hi fastrack1966:
What CCleaner product and version are you currently using (and was it downloaded from an official CCleaner download site like https://www.ccleaner.com/ccleaner/builds), what specific file is detected as a possible threat by MS Defender, and what is the name of the detection?
I’m currently using CCleaner Free Portable v6.30.11385 on my Win 10 v22H2 laptop. See my 20-Oct-2024 MS Defender Detects Portable ccsetup629.zip as Trojan:Win32/Sonbokli.A!cl about MS Defender detections I’ve been seeing for the past two portable builds, namely ccsetup629.zip (released 16-Oct-2024) and ccsetup630.zip (released 13-Nov-2024). So far I haven’t had any detections for the CCleaner64.exe executables bundled inside those .zip files.
Dell Inspiron 15 5584 * 64-bit Win 10 Pro v22H2 build 19045.5131 * Firefox v132.0.2 * Microsoft Defender v4.18.24090.11-1.1.24090.11 * Malwarebytes Premium v5.2.2.154-1.0.5101 * Macrium Reflect Free v8.0.7783 * CCleaner Free Portable v6.30.11385
