It always opens on my computer and I can't get rid of it.

All I know is when I turned my computer off the other night, there was absolutely no sign of any program running, but before windows would shut down it said "ending program shellmon" then after it ended that, my computer shut down as I wanted it to. So I don't know if that's a bad thing or not? Can anyone tell me?

When I go to shut down, it says ending shellmon.exe?
   
shellmon.exe Can be shutoff if you first turnoff the aolware.exe process, then shutoff shellmon.exe process. Otherwise shellmon will keep returning to the process list immediately even if you try to shut off the entire process tree.

not much except it is denied when you call aol

AOL Desktop seems to run better without it IMHO. Either remove it in safe mode or rename the file and kill it in task manager.

Best practices for resolving shellmon issues

A clean and tidy computer is the key requirement for avoiding problems with shellmon. 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 doing a repair of your installation, or in the case of Windows 8, 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 shellmon.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.
