The virus appears at a random place in a random camera and you have a few seconds before it "attacks".
The attack phase works kind of like this, it closes a random amount of vents at random places. If a fewer amount is closed, you can save yourself from suffocation. I noticed one point that is has a chance of not doing anything, but this is rare (since it's random).
It can also put up ads randomly when you open your monitor, and the higher the AI, the more ads (sounds like YouTube).
