If it turns your pc slow, try to upgrade the intel matrix storage driver, if your do not use a ssd cache or raid, you can uninstall the driver and install the intel chipset driver to use the basic sata drivers
Same problem as @JeffCurd. Caused CPU spikes on interval-basis, laggy music etc. Detected using Process Explorer. Deactived AANTMON.EXE in task manager. Problem gone. Thanks! Find the solution thanks to Process Explorer

If you've been having problems playing MP3s, getting brief periods of 'fuzz' and lags this is probably your problem. Took me ages to track it down, they must have changed something recently as problem only only appeared a week or so ago. Disable it and MP3s now play flawlessly.

Source of stuttering in sound. Also caused excessive CPU usage for about 20 seconds every couple of minutes. Caused jumpy and slow mouse movement. Removed as I already have a RAID controller and didn't need this one for onboard RAID. All problems immediately ceased.
This file caused an anoying Buzz in music files! Disabled and buzz gone :oD . File used for raid systems so should be removable if not using raid. Would be nice to find the conflict

Installed with Intel Matrix Storage Server. Need if you have a RAID setup. You should be able to stop this process if you don't have a RAID setup
It's Intel

Best practices for resolving IAANTMon issues

A clean and tidy computer is the key requirement for avoiding problems with IAANTMon. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the IAANTMon.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
