Question High RAM usage for no reason (IDLE)

Do you have screenshots from more than a couple weeks ago when it was using less? Did anything new get installed or changed a couple weeks ago?
The usage doesn't really seem unreasonable. Try performing a full system virus scan and let us know if it finds anything.
 
No, I don't have any pics. A lot of stuff has been changed, but I deleted everything that has been installed so it should be just like it was a few weeks ago. Well, at idle it just sits using like 4-5GB of RAM, and it really slows things down.
