There should be some way to customize a hack.

i.e.

I set my virus to be very fast with Installations but slower on Null Cannons

or

I set my hack time for Null cannons to be faster but the Virus upload time is longer and Installation hacks are slower

or

My virus shuts down the entire Null Cannon while it loads

something like this.

Yes, I would like my virus in blue please.

Smartass

Hey wait you are onto something.....what if as you virus uploaded, the Null Cannon flashed any color you wish, to confuse....make it look as if it's already there's and that they are hacking it lol..
