I watched a couple of TF reviews on YouTube that were done less than a year ago. Both tests had it at level 3. It still did pretty good on one review. It did much better on the second review I watched.
I would really like to see a review of TF set to level 5. I only saw one review of it at level 4 and the guy running the test complained and knocked it back down to level 3 because he did not white list killswitch and a couple of other apps.
If someone does test it, set it to level 5 and white list anything other program that will be running along side TF for intelligence gathering purposes; such as, Process Hacker, or Killswitch. I think you will be surprised at what it prevents. At least 20 malicious links should give us a good idea.
I know that if winsevenholic would have set TF to Level 5 instead of leaving it at default level 3, it would have caught everything, or at least all but one:
