I've recently encountered an issue where my internet addon antivirus (in this case Malwarebytes) has detected many instances of the same service that it has flagged as malware while trying to boot up a specific game on the website. This leads to the game never loading up, while the instances of the "malware" keep piling up in the antivirus dashboard.
From what I've checked, this doesn't happen all the time, but only around evening hours.
I was also unable to replicate it on any browser other than Firefox.
