But we thought computer nerds loved comic books? LOL!

The release of The Avengers has shot Mark Ruffalo from movie star to mega star -- making him way far bigger prize for celeb hackers.

Sunday the scene-stealing-actor's Twitter was hacked by a horny nerd. His/her first tweet: tweeted:

"It's kind of hilarious me getting hacked today. I got to hand it to the hacker. Kind of genius."

It may be easy to piss of the Hulk, but it takes a whole LOT to rattle a guy whose flick just became the #1 movie in history!!!
