While Malwarebytes AdwCleaner Portable is the gold standard, other portable tools exist:

Adware evolves daily. The portable version does not auto-update. Download a fresh copy from Malwarebytes every two weeks. The version number is in the top-left corner of the UI (e.g., v8.4.0).

Usually 1-2 times per month. Check the official website or the https://downloads.malwarebytes.com/file/adwcleaner direct link.

: Perfect for a "USB toolkit" to fix multiple PCs.
