The title pretty much says it all. I DL'd the latest update then ran immunize. It got part way through the process and then froze. I tried starting the program up again and running it again, and same problem. So I gave up on the immunize for the moment and ran the scan. The program began using 98% to 100% of the CPU. It didn't hang, but its resource usage remained this high throughout the entire scan. I've never had this happen before.
