FUSE to old for Mac-OS 10.14

After updating to Mac-OS 10.14 i am not able to get rid of the following message: "Unsupported macOS Version. The installed version of FUSE is too old for the operating system. Please upgrade your FUSE installation to one that is compatible with the currently running version of macOS". I can not find FUSE among my applications. How and why should I upgrade? Is this a bug in Mojave? How can I get rid of these five messages who clutter my screen?
