the tuner.exe I have is a guitar tuner - it's 4168 KB and sits where I downloaded it - it makes guitar string sounds so I can tune to it - I think you are talking about another tuner exe

The Marimba tuner is considered adware as it is often installed by AOL Instant Messenger, but it also can be used for legitimate purposes in corporate settings (i.e. as a remote software installation platform)

It is an enterprise configuration management client by BMC (formerly Marimba). It allows the server version to monitor your PCs config, installed software etc. for inventory or remote management purposes. Your IT people are responsible for its installation and management.
Tuner is the client component of marimba infrastructure and the tuner.exe process runs on the client machines to enable the communication between client machine and Repeater transmitter for installing or updating the patches on the client machines.

Jimbo is correct. Has nothing to do with music or AOL ... LOL.
It can 'hog' your CPU causing your system to run slow. Tuner.exe caused the CPU to run at 98% on two computers running Windows XP. I have not found this application on any Windows 7 machines at this time. Four Windows XP computers have this installation and it cased problems on tw o computers. I have found that Tuner.exe will take over 50% of the CPU and it runs in the background.
Windows 7 32-bit. the java.exe is what's running constantly at 50% CPU within the C:\Program Files\Marimba\Tuner\lib\jre\bin directory. This seems to be what's causing my laptop to randomally shut down 2-3 times a day as the fan can't kkeep the CPU cool enough so it shuts down due to too high of heat.

Best practices for resolving Tuner issues

A clean and tidy computer is the key requirement for avoiding problems with Tuner. 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 Tuner.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.
