First my apologies if I am in the wrong place or format. I am new to the forum and have little experience in posting generally.
My problem: since yesterday (Feb 2) my W10 custom built computer unpredictably and at irregular but longish intervals goes "ca-ching"
I say that because I googled and found two sound files for cash register sounds and the sound is exactly like the second, so labelled.
Tried:not my printer - occurs even if switched off. I have Firefox and Outlook open most of the time but not related to activity - happens if I am not doing anything. Event viewer files (I am no expert) no help. I looked through Windows Sounds but could not find anything connected to this sound.
I wonder if I am hacked - though Kaperky records no event, Malwarebytes and MW Anti-Exploit seem happy.
Any advice would be very welcome
I have uploaded the sound file I got from the net
