The most weird malfunction ever please help

What is happening. First, I couldn't open anything at all. Then I shut down my computer, press F8 to system restore but it didn't work. And now I'm at the screen where I'm supposed to sign in with my password but all of the font has changed (it looks like a random symbols font.) and my password doesn't work... is my computer impossible to fix now? I've posted this from my cellphone. My computer is brand new, got it few weeks ago. An Asus one. Trovi appeared on my search browsers last night and warden too, I had a hard time removing them, and then this happened. I didnt know trovi was that severe?
