Yesterday I noticed that itunes was acing weird, after playing a song for about 10 seconds, CPU usage as seen by the task manager would spike to 100% for a few seconds which would cause my system to respond very slowly. I first had no idea what was causing it so I installed the newest version of itunes but that did not fix it. I then remember back to what I had changed on my system that day and remember that I had configured NOD32 using Blackspear’s extra settings. So I opened NOD32 and looked at the files AMON was scanning when I played a song. It turned out that as the CPU spiked to 100%, AMON was scanning several files such as the song, my itunes music database among several other files. I then unchecked “scan all files” under the extensions tab for AMON, re-booted and the problem was solved, itunes is now back to normal and not spiking to 100%. I would like the added security that “scan all files” provides but the slowdown it causes in itunes is unacceptable as I always and playing music on my computer. So I am wondering if I could somehow exclude AMON from scanning those files every time I play a song, maybe by adding some file extensions to the exclude list within AMON? If not I guess it’s not a big deal, as I do run weekly on demand scans which is set to scan all files.
