The mouse or touch pad is an essential piece of hardware that is used to navigate folders, launch programs and access a computer's right or left-click options. Sometimes, users may face issues where the mouse or touch pad starts moving around erratically, and merely pointing the cursor on an icon causes the program to launch automatically. This issue is also known as an automatic click issue.
The most common cause of this problem is an outdated driver. Luckily, updating the old driver is a quick fix that should get your mouse working correctly again.
