Reverse engineers who decompiled the horror.sys driver found code that didn't make sense. It referenced hardware interrupts that don't exist on x86 architecture. It contained a string of text that translated to a set of GPS coordinates. The coordinates led to an empty field in Belarus. Beneath the field, according to Soviet-era records, was a decommissioned bunker that once housed an experimental biofeedback computer.
