Okay, I'm going to set you up with a few starters here.
I heavily recommend that you learn basic musical theory. That doesn't mean reading sheet music, what it means is you should know the names of the notes that you're playing.
A A#/Bb B B#/Cb C C#/Db D D#/Eb E E#/Fb F F#/Gb G G#/Ab
The # represents "sharps" and the b represents "flat". The reason that notes in between are written "A#/Bb" is because they can be one or the other based on your preference. Notice how it looks like A-G from the alphabet with alternate notes in between, and how simple that sounds. That's because it is.
Now, learn basic major and minor scales. Figure them inside and out, and that doesn't mean playing them over and over (but that would help). Find out what makes a scale a scale (it's easier to understand than you think once you know ostensibly what "notes" represent).
You've already heard people talk about "tabs" or tablature. Here's a video that explains what that is, how to play it, and other essential knowledge for beginners.
The internet will provide you the tablature for almost every song you can think of (as long as you keep it mainstream a bit, no local indie rock). As before mentioned by another user,
Ultimate Guitar is a great as long as you ignore their horrible online community and news service. Know that you don't need to play every part of a song that's written in tablature as a lot of songs these days use multiple guitar and rhythm tracks that can confuse a weary beginner.
Here's something crucial if you want to play rock music:
LEARN WHAT POWER CHORDS ARE. They're in every rock song since the 50s. It's a basic figure shape that can play chords for every note on your low E and A string. Once you know that, you can already play 90% of AC/DC's discography (and everything by Andrew WK, on a personal note).
Okay, that should set you up for the basics, message me for any questions. On one last note, some people might recommend that you get payed lessons. I personally benefited from them, but it took a while for me to find a worthwhile teacher. Be wary of the Sketchy McSketchersons that pollute the pool of great guitar teachers in the United St- (looks at profile) -I mean Sweden.
Once again, if I confused you deeply with something, just message away. Committed Escapists gotta help each other out.
