Microsoft Windows 10 (64-bit)

Out of nowhere my computer starts opening pages and clicking links and typing messages on facebook and sending them to my wall. not any specific words just letters. when i close my browser i can see little dots on the screen like someone is touching it. it started months ago and at first it was funny but it's really scary now. i was told to clean the screen and i did and it worked great for about a week and now it started again yesterday. i cleaned it again and now that i turned it around to see the serial number i saw all the vents were full of dust. i cleaned them all out. could that be the problem? other than my computer has a ghost inside it?

@torilinda -- what happens if you disconnect the computer from the Internet, by unplugging your cable-modem (or other type of modem your ISP has provided) ?  If you still see "random" characters, then it is not a "hacker" on the Internet who has control of your computer.

 

If you unplug the keyboard, do those actions still happen?

Then, if you have, or borrow, a USB keyboard, and connect it, do those actions still happen?

 

You might be on to something -- dust inside the keyboard, or maybe dust on the motherboard that is causing short-circuits.

 

Power-off your computer, and disconnect it from any power source, and take a can of compressed air, and "shoot" everywhere into your computer, to dislodge dust.  For a desktop computer, maybe remove one side-panel, and "shoot" at the fan & the heat-sink on top of your processor, to physically de-dust it.

Thank you so much for helping me!! I do beieve it's the dust and I have to buy that compressed air can and I will. It's been ok since I cleaned it but I know theres more inside. I know dust id killer but I never move my computer because of the cable for my boes in the back. It pulls out when I move it. I have a new usb keyboard and it's an all in one. When I did pull it forward to see the serial number I saw the dust in the back. I got it all out as far as I can see but I'm sure theres more inside that I pushed with the little brush I used. Thank you again.
