CPU And Memory Incredibly High

for the past year or so- it has had this issue of incredibly high CPU and Physical Memory usage- I'll show a screenshot with my Task Manager up so you can see.I found this website by searching in google- and it led me to this thread: url...So I tried HijackThis- and I'll paste below what I got; including the error message that popped up when it first ran.But before I show you guys the screenshots and such; lemme e'splain. I almost NEVER turn off my computer- yes, I'm a horrible person, I know. And it's a laptop that I never take off the charger- again, horrible person, I know. Sorry. Not the point- and I do constantly leave up Photoshop and Google Chrome because I am either playing music or just don't have the patience to close and reopen them every couple of hours. HOWEVER- before recently; when I hit some very bad viruses (or at least I believe I did) my computer didn't mind running PS CS4 and Chrome- even with multiple tabs open. I contracted some horrid virus- and I don't remember all that happened but I took it to a store on my college campus and they repaired my computer- so all's well that end's well. After they fixed it- it worked great for a couple more months, and now maybe I have another one? All I know is my fan won't turn off and I can't even touch my desk under my laptop with how hot it is.
