Well, the Matrix was all about a computer virus, but if you are really asking if we are really living in a massive computer simulated world, I'll take a crack at it, as it has been going through my mind a lot lately.
To preface ... I am not a religious person by nature, so I guess you would call me agnostic in that respect. I am a big believer in faith however, and base my faith mostly on Judeo-Christian teachings. IMO, the world needs more faith and less religion. There would be a lot less war in the world without it.
Since I come from that background, I am monotheistic (one God or 'supreme being' as it were). Many other religions follow this thought too, so if you share that philosophy, it would not be a stretch to believe that we are really all just 'living' in a really advanced version of The Sims. The entity playing the game is the "supreme being", makes the underlying rules, and let's the program run. It can stop, restart, change the rules, etc. It would also explain the "Big Bang" and why there appears to be so much order in the physical world and mathematics.
Q: Who is your favorite character actor?
