Minecraft Forums

Hello everyone,
I believe this is my first post ever, so I apologize if it is in the wrong category.
I've been playing minecraft for a very long time, never a problem, but a couple days ago my dad decided to use my computer; and funny enough, not Minecraft won't work.
Here is the error I get:

After that, it allows me to click on "Play Offline" just to crash when I select any of my worlds (online servers ping endlessly)

Can anyone tell what the problem is?
I tried uninstalling programs that magically appear on my computer on occasion as well as removing Java entirely and re installing it.
I also tried changing my client from Forge 1.7.2 to Vanilla 1.7.2 as well as OF 1.7.4 and 1.7.5 and their Vanilla counterparts, all unsuccessful.

Any clue what is going on?

I just figured out how to fix it, after all day doing research.
Theoretically I should delete this now, but I'm going to leave an explanation of how I fixed this here if anybody needs it:
All i did was follow this link and did what the "Best Answer" says:

I apologize for posting such a gigantic question and then finding the answer myself, but at the very least I hope someone finds use in it (Until an administrator deleted the thread).
