Honestly, the most common reason I’ve run across mouse pointers going for a random walk around my screen has nothing to do with hackers or malicious software.Įither the mouse sensor is dirty, or the surface it’s on is dirty. As always, if you suspect malware, run up-to-date security scans.

While malicious movement is possible through traditional remote-access software, bad actors more commonly take steps to hide what they’re doing, thus not moving the mouse pointer at all. Sometimes the surface, even clean, can be ‘confusing’ to mouse electronics, which can manifest as autonomous movement. Mouse pointers most often move on their own because of dirt on the mousing surface or dirt within the mouse itself.
