I recently upgraded my MacBook Pro to High Sierra and found out that it started working very slowly. As Activity Monitor says, the process YaraScanService is the one to blame. It's eating about 10GB of memory or even more. When I stop that process forcely, my computer start working as a charm. I also tried to reset SMC and NVRAM, but it did not bring to any result (maybe it just started to start up a little bit faster but stil). I heard that the process is supposed to do its work and then deletes itself, but I waited for some time, and it did not remove. What do I do to solve this problem?
