my mouse randomly clicks by itself.. when i am scrolling by things it clicks on them and my keyboard will press random buttons too. my start menu randomly pops up and when im on a website my mouse will randomly press the back button. i ran malwarebytes and no luck.. ....
Which keyboard and mouse (make & model, size, etc.) are you using?
Is it possible to use your keyboard and/or mouse to record a "macro" that will be executed if you assign it to a specific key-press, or to a mouse-button click? You can do that with some keyboards and mice as a convenient way to send input to a program such as a game. You might be unintentionally activating such a macro.
Do you know whether a program that you use has a feature to record a "keystroke macro" that will be "played back" when you press a key or select a menu icon, etc.? If such a program is running while you are doing the things you describe, then it could be interfering.
There are some programs that have a feature which records the keystrokes that the user makes and stores them in a "log". That is legal when it is something that you want to use and/or an employer requires you to accept.
"Remote Desktop" software can enable someone to use their mouse and keyboard for input to the operating system or to a program that is running on another computer to which their computer is connected. If you have allowed anyone to use remote-control software to access your machine before the events that you describe began happening, then there could be something that is still running on your computer that you need to halt. Of course, malware can do that, too, without your prior knowledge and consent.
Also, malware sometimes installs a "keystroke logger" on your computer to capture passwords, credit-card numbers and other important data. The malware might have a bug which causes the events you describe to occur "at random". However, I don't know of any specific malware that records mouse cursor movement or buttons that are pressed, and sends them to a data collection server via the Internet.
Many anti-malware scanners can detect a "keystroke logger" -- some are designed specifically to examine the computer to see whether they can detect one. Some of them have such a feature that is disabled by default, and you must enable it to detect keystroke loggers. However, many other anti-malware scanners either cannot detect a keystroke logger or often fail to detect one that is present.
