Computer typing by itself

[Pizzasaurus]

So I was talking to Steam Support about my account then my computer started to retype the things I said. I thought it had to do with my macros because it has been acting up recently, so I opened a new tab to let the typing finish. But now it was typing different things. It ended with "asdfqwerhsdvlHAHAHAHAHAH." It hasn't done anything else after that. I did virus scans, but it didn't catch anything. What should I do?

You have been hacked.

What should I do about it?

1. Unplug your ethernet cable or turn the WiFi off
2. Deep virus scans with multiple tools.
3. Malware scans with multiple tools. Malwarebytes, HotmanPro, etc.
4. After, change ALL of your online passwords. All of them. Preferably from a known, non-infected, device.

What led you to contact Steam about your account?

I had a problem with Steam Guard and it wasn't sending me text messages.

In any case...If you see "asdfqwerhsdvlHAHAHAHAHAH" appearing on your screen, and you personally did not type those characters...you have been hacked.

Hard.
