ARC final mission

[affectiosus]

Hi there!
First I want to say that I completed the game at least 10 times, but only if I'm working for Arunmor.
When I choose to work with ARC, I can't complete the last mission because I get busted for "working with Andromeda Research Corporation".
I've done everything to make infection faster - custom gateway with 84 CPUs, mouse macrosses for "cd usr" and "run revelation" strings, but still stuck. I think I am fast enough - infecting 4-5 systems per 2 minutes, then deleting InterNIC logs.
What am I doing wrong?

Update.

I've tried another kind of hack. Before ARC sends me a 3.0 revelation, I've hacked every Internal Services machine and uploaded a copy of revelation 1.0 there. Then, after i recieved tracked and final version of virus, I simply hacked again into every internal services machine that contains revelation and run it. After 15 or so infected machines screen turned black and something about "internet core provides have shit 101010001010101" appears. Looks like i've been successful
