What is ACMON.exe?

The genuine ACMON.exe file is a software component of ASUS Splendid Video by ATK (ASUSTeK Computer Inc.). This Utility for ASUS graphic cards and notebooks improves contrast, brightness and colors such as skin tones (as in Webcam videos) on an LCD display. Press Fn + C on your notebook to open the tool, which is a part of ASUS's so-called Splendid Video Enhancement Technology. Four engineers from Acer founded ASUS in Taiwan in 1989 as a motherboard manufacturer, taking its name from "Pegasus," the mythical winged horse. ("Asus" also means "eminent" or "grand" in Chinese.) In 2008 they split three ways into Asus, Pegatron, and Unihan. They spun off Pegatron, their OEM motherboard manufacturing arm, in June 2010. They manufacture PC components and peripherals, notebooks, tablets, servers and smartphones. With revenue over US$11.9 billion and a technical park occupying 540K square meters, (besides other worldwide locations), their website says they have nearly 40% market share in motherboards, (#1 in the world), and are the leading technical firm in Taiwan.

Asus Compatibility MONitor (ACMON).exe; (ASUS bloatware; see "Splendid" comment above) - I left it on is because I came accross notes referening to ACMON as workaround for issues between some Skype (VOIP/Video) type apps and ASUS... but i could be wrong.

Came installed on Asus laptop when new. Frequently fails to close automatically when shutting down Windows, requiring manual forced shutdown. When terminated at the start of a session, does not appear to have any adverse affects; supposedly related to video, but both viewing and broadcasting video seem unaffected by ending the task via Task Manager at the start of a session.

Best practices for resolving ACMON issues

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