Thanks for everyone who asked about my computer. I somehow got some virus/trojans and it started messing stuff up. Especially Google... so every time I did a search and I clicked on a result, it would open in a new tab (which I don't like) and half of the time, it would be advertisement, instead of what I've been looking for... Luckily, it wasn't porn :P
I've been toying with the idea of re-formatting my computer... however, I never did that and it can be quite complicated. I ended up doing a PC restore, which is bringing my computer back to its original state when I just received it from the store. It did work (thanks god), but I've been using AVG as my spyware and I think that was part of the problem... so I had to do it all over again and use another spyware.
So now, my computer works well. Hopefully, it'll stay that way :)
