Armsvc.exe

Regarding the issue with the "^" key, I was able to find the location of the file; it was in the "Roaming" folder of my user account.
By enabling the display of hidden files, I was able to delete it.
I then cleaned my registry with Glary Utilities and restarted: no more issues with my keyboard key.
However, and I'm not sure if this is related to that file, most of my Windows sounds are "cut off."
This problem was already present before the deletion of "armsvc.exe."
For example, the sound that plays when a USB device is connected lasts only a fraction of a second.

Edit:
I believe this is coming from my headset because my other audio devices are working perfectly. I am waiting for a possible reply from you before marking my topic as resolved.

Edit 2:
The sound issue is coming from the Razer Synapse software that manages my audio headset. Probably a bug due to the latest update.

It’s probably a RAT (Remote Access Tools) infection you have.
I advise you to change all your passwords. - they have probably been stolen.

If you still have the file in question (in the recycling bin, etc.), send it to http://upload.malekal.com
if you have any idea where you picked it up, I’m interested.

Like the angel you are, you laugh creating a lightness in my chest,
Your eyes they penetrate me,
(Your answer's always 'maybe')
That's when I got up and left
