What is PXIMouse – Should You Be Worried? 

I can’t deny that computers have been an integral part of my personal and professional life, yet the fact that how little I know about its ins and outs still intrigues me. There are a lot of programs and features I use but don’t know what’s their purpose in my PC.

Recently, when one of the word processors stopped responding, I did what every techie would do – open task manager and eliminate the nonresponding process. That’s when I noticed something unusual, an executable that I’d never seen before. 

Operating with the name ‘PXIMouse’, the executable started automatically without my intervention and continued running in the background.

Moreover, it was consuming quite a lot of my computer’s processing power, so I was also a little skeptical about it. 

The program made me worried because I didn’t want my data to be monitored and spied on. So, I decided to investigate this nifty file and check if it’s harmful to my data and privacy. What I found will astonish you as well…

What is PXIMouse?

After researching on several tech forums and reaching out to Microsoft support channels, it came to my knowledge that PXIMouse is an application that tracks your keyboard and mouse activities. While it sounds quite scary, the data isn’t shared anywhere else. 

It may also appear by the name TiltWheelMouse.exe and is installed the moment you plug in a mouse to your computer.

As everything works in the background, you won’t be able to see its installation status but the application does show up on Task Manager. 

Therefore, this piece of software is essentially a mouse driver that facilitates the functioning of your optical devices.

However, certain users have reported that some malicious files disguise themselves with this name and infect the user’s PC.

That’s why I decided I should run a quick scan for the file on Virus Total. Fortunately, in my case, the executable was completely clean and didn’t carry any kind of virus or trojan, but you should check this at your end too.

What If You Delete the PXIMouse File? 

If your mouse includes PixArt sensors shipped by PixArt Imaging Inc, you’ll find the PXIMouse executable on your computer.

This means it is indirectly supporting the functioning of your mouse and deleting it may cause issues with its operations. 

In case you choose to delete the PXIMouse file, you may encounter certain error messages such as: 

  • PXIMouse has stopped working. Windows is checking for a solution to the problem… (Windows Operating System versions 10, 8, and 7)
  • PXIMouse has stopped working. A problem caused the program to stop working correctly.
  • Windows will close the program and notify you if a solution is available. (Windows Operating System versions 10, 8, and 7)
  • TiltWheelMouse.exe has encountered a problem and needs to close. (Windows Operating System version XP)
  • Access violation at address FFFFFFFF in module TiltWheelMouse.exe. Read of address 00000000

Luckily, most of these issues can be mitigated by keeping the executable updated to the latest version, so make sure you not only keep it in your system but also update it from time to time.

Is PXIMouse Infected? 

PXIMouse is simply a driver that helps the functionality of some mice available on the market, particularly with regard to the side buttons and other extended functions of the mouse beyond simple point-and-click applications from the optical sensor.

While it’s true that there have been some cases of malware hiding in your computer by masquerading as TiltWheelMouse.exe, which is related to the PXIMouse file, those cases are rare.

It’s more likely that the PXIMouse service is simply running on your computer for legitimate purposes and you don’t need to worry about it.

That said, if you do find an instance of TiltWheelMouse.exe that isn’t located in the System folder on your C drive (the main hard drive on your computer) then you should take a careful look at it because it could be related to the malware and harmful to your computer.

A Few Words About PixArt Imaging Inc. 

PixArt Imaging Inc. is a manufacturer of various kinds of optics including CMOS image sensors, capacitive touch controllers, and sensor chip designs.

It is currently one of the biggest suppliers of optical mouse sensors for conventional and high-end mice for both general computers use and high-end gaming.

One of the features of PixArt and its sensors is that they use proprietary algorithms. This, paired with their short design cycles, requires that the sensor interacts with software on the computer in order to ensure that everything is working properly and the mouse operates smoothly during every use.

In order to achieve this, PixArt has developed a number of algorithms that are compiled into an API.

The API is then used by software companies to implement PixArt’s sensors into their products. For example, Pixart sells its sensors to Logitech who then uses them in their gaming mice.

Bottom Line 

It is likely that you will never even realize that there is a program installed necessary for your mouse to operate.

This is because this program is necessary, and it goes without saying that having a computer with no way to control the cursor is tantamount to losing all of the functionality of the computer.

You should not, therefore, be worried about PixArt Mouse Commander or other PXImouse variants.
