I had the same thing as zappozeppo 2 days ago. Anti-Ransomware detected the OfficeClickToRun executable and quarantined it, but it did not appear in the quarantine list. When trying to start Office products, it said office was busy updating or something like that. Disabling protection and rebooting did not help it show up in the quarantine list. Uninstalling Anti-Ransomware entirely did let office start running, but now I don't have a MBAMService\logs folder to upload. I can't find the specific executable it had detected as the path was so long it didn't show it fully to me, and without it being visible in quarantine list, I can't help with that. I'm attaching my Anti-Ransomware folder from ProgramData (P.S. I thought I wrote a similar reply without the attached logs 2 days ago, but it didn't appear when I came back to post an update. Moderated?) Malwarebytes Anti-Ransomware.zip
