ready to throw my computer out the window!

Hi,

I'm pretty sure it has a virus or something. It has a difficult time starting, my background dissapeared, it runs slow...
I downloaded bitdefender and mcafee. Neither has done anything. I'm not sure they are even completely installed. when I try to open the link in my download file, it either does nothing or tells me the environment can't be found. I'm so frustrated! I've wasted $70 on downloading software. can someone please help me!?
