Thanks for the replies.
I've since deleted the game and run several scans using malwarebytes and sfc/scannow with nothing untoward cropping up. What works best for me seems to be doing a couple clean boot ups and then this problem vanishes for the day. For the day being the problem. Every morning my problem seems to come back and I have to do the same thing everyday to get rid of it. Any tips?
On another note I'm not sure if this is related to my current issue or whether it's a coincidence that it's happening at the same time but my computer doesn't seem to want to recognise when I have headphones plugged in or not. To elaborate; sound works fine through headphones but when I take the jack out I'm greeted with dead silence from whatever song I was playing. I've done a test of my speakers on Sound Blaster and they worked fine then and made sound but to switch to either speakers or headphones I have to manually go to Sound Blaster and tick the appropriate box.
