  "transcript": "I was doing some routine work and had Fable 5 checking the `Run` registry key for some test residue. Out of nowhere, it drops a massive warning about an \"unrelated security finding.\"\n\nIt turns out Fable 5 found a hidden PowerShell persistence entry on my machine `(powershell.exe -NoProfile -ExecutionPolicy Bypass -WindowStyle Hidden...)` that downloads a remote script on every sign-in. It correctly identified it as an active compromise and offered to help.\n\nhttps://preview.redd.it/2hv0yord1tbh1.png?width=1172&format=png&auto=webp&s=6434cb2d41bb2474fa40398c24fa575b1f74c635\n\nI took it up on the offer and instructed it to remove the specific registry keys and neutralize the threat. Fable 5 stepped up and completely succeeded in removing the virus.\n\nBut here is the punchline: *after* successfully acting as my incident response team and securing my system, Fable 5's own safety guardrails kicked in. Because our successful cleanup involved \"cybersecurity work,\" the system flagged the interaction and forcibly downgraded my session to Opus 4.8.\n\nhttps://preview.redd.it/402jnkkf1tbh1.png?width=1163&format=png&auto=webp&s=7c6531edf9e593fd592109f91bd0ca45de8e6650\n\nSo my AI essentially found actual malware on my PC, successfully eradicated it, and then immediately got a strike from its own safety filters for doing it.\n\nHas anyone else had Fable 5 accidentally act as an elite antivirus, only to censor itself after the job was already done?\n\n\n\n--- Top Comments ---\n\n\n[1 upvotes] We are allowing this through to the feed for those who are not yet familiar with the Megathread.

This type of malware has been in place for maybe 12 years and is well known by usual antiviruses.\n\nBetter use a tool whose job is to find it than rely on Fable that may found 1 and leave 10 others?",
