OS 7.1/7.5 forgotten games/names

I had this game back in the game, I don't remember what it was called, but I'd sure like to get the name. I'm building an OS 7 VM, and want to try to find some of the old games I used to play.

Anyways, It was a "simulator" of sorts in that you played the part of a either a network firewall or an anti-virus (can't remember which exactly) and had to defend the computer from Virii and hackers and such. It was sort of like a mid 90's 3D (2d graphics) version of Space Invaders, with the baddies coming from the back of the screen to the front (about half ways up, vertically to the bottom - getting larger the lower they got) and the good guy/player had a low sweeping arch to travel along on the bottom of the screen.

I know, this sounds like either it's some trojan/virus game or so generic that I should be able to find the same gameplay in another game. Well, It was a legit game, bought it in like 94 from Babages. It's also quite unique, regardless of the general description commanilities with at least half a dozen other games. I've also been trying to think of the name of the thing for the last 10 years, on and off. LOL!
