Mouse clicking at random

[Cpt. William]

So, as the title says i have been experiencing something very weird in the last few days. When i use my computer it will randomly start clicking the mouse and writing things on the keyboard. It's probably not someone taking control over my pc though because it doesn't move the cursor around or write things that could get them control over my pc. Just about ten minutes ago i was trying to open my browser and it started clicking the mouse and spamming letters like asswwwwwwwwwwwwwdddddaaarrrrrreeee and i couldn't stop it. I can't remember downloading anything sketchy and virus scans resulted in nothing. It did this for like 2-3 minutes or so before it stopped. This has happened every day this week. I have a Razer keyboard so at first i thought it was the razer chroma software messing things up so i uninstalled that and rebooted but this still happened. I have a Steelseries rival 310 mouse and a razer blackwidow elite keyboard. This is a fairly new installation of windows 10 too, about 2 months. Any form of help would be greatly appreciated:)
