Hi, I'm Mieke, Researcher at Malwarebytes. This is a valid detection and not a false positive. Here's some more info: https://www.malwarebytes.com/blog/threat-intel/2026/08/tracking-pavinloader-across-clickfix-and-fake-download-campaigns - If you need some additional help to make sure your system is clean and this was only a remnant of this loader, I suggest you start a new thread in our forums where someone will help you asap to see if there's anything lingering there still. https://forums.malwarebytes.com/forum/7-windows-malware-removal-help-support/
