In the last episode (Better Angels) of AMC's The Walking Dead, Shane and Randall became walkers shortly after dying:

According to Wikipedia:

This episode suggests that the zombie outbreak could be spread through unorthodox and unidentified means

It ocurrs to me that everyone is already infected and they turn into walkers after they die unless they die from some kind of cranial/brain blow. If this is true then scratching and biting doesn't turn you at all but you do get infected.

I don't know if this make sense to you, so my question is: Does anybody have a clue about what is going on here?

I think your hypothesis is correct.

Going by what was said on the after-show, The Talking Dead, and the general consensus on the official site from AMC, we are indeed being presented with a plot device that sees everyone being infected with the 'zombie' virus, which is then activated upon death.

Yes, you can be turned from a bite or bad scratch (or at least the turn is accelerated), but now that just dying has been thrown into the mix, it appears that head shots are the way to go for everyone :)

I feel that I have just confirmed what you already thought, but I hope this is of help.

Really helpful. Thanks! I'm still don't know if you can turn with a scratch or bite, I guess we will have to wait for that –  César Mar 15 '12 at 16:48

No one realised, about all the mix of zombie blood in the parking fight? Shane and Rick got cover their wounds with zombie Blood, this imo count as infection factor Using the Knife, to lure the zombies at the gate also counts.

Everyone already has the virus. If they are bitten by a zombie then it kills them and makes them a zombie. If they die naturally and do not receive a bullet or blow to the head, they will "rise" as a zombie. If bitten, they will turn to a zombie unless the sustain a head blow; then they will become a corpse.

Shane, just like everyone else, has the virus in him. When he gets shot by Rick, he rises as a zombie because he was not shot in the head. Once shot in the head he is a corpse. Randall also had the disease and he was killed by breakage his neck and when was left there "dead" rose as a zombie soon after.

Basically, no one is immune, everyone is sick and there are two ways of being turned; killed without a huge trauma to the head or a bite from a zombie which my theory is increases the disease in the body and accelerates death and immediate zombie transformation. The only way to kill anyone, zombie or "not zombie", is trauma to the head.
