It's the touchpad driver that's included in Dell notebooks. It uses a lot of I/O. Closing it simply reverts your touchpad back to it's default sensitivity, which I do think is bad at all, and videos aren't choppy on my PC anymore

Appeared after installing Dell Trackpad driver.
In task manager it shows as ApntEx.exe and it appears to use 10 times more byts in I/0 other than any other programme. My touchpad is always hard to operate sometimes having to double click 3 or 4 times for it to respond

Huge amount of I/O bytes from this process - greatest of all processes on my Dell 830 laptop

I looks like another file has replaced this file. My mouse goes crazy all the time. I'm trying to put the original file back on my Laptop. I've tried several virus removal software applications however none of them work.

Best practices for resolving ApntEx issues

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