Like DJflan, I think it's likely a custom-designed font. It's a very low-resolution bitmap font - pixel-based, at a fixed size - to best fit the number of pixels in the given LCD display. It's not designed for scaling up/down in size (like PC true-type).
You would be able to design a true-type emulation of it for PC, but it would only look good at certain font sizes (multiples of 1x, 2x, 4x, 8x, etc. sizes of the original) otherwise the pixels will be aliased/distorted (due to the blockiness of the fixed pixed-based design).
A good example of a pixel-based true-type font for PC is
Redensek. I like that font.
It looks small on our screens as we use such high resolutions compared to LCDs, but as mentioned multiples of the original pixel sizes works well.
Again, it's only ideal at certain sizes (as shown) otherwise it becomes aliased, and any anti-aliasing blurs it irregularly.
So you could translate the Virus' font over to PC, bearing in mind those same limitations.
