Volume Control is missing?

I just realized that i no longer had volume control and no sounds except for a big beep when i try to download the driver from hp's site. I am pretty sure I have some sort of virus/malware on my computer since i no longer have the start menu or icons and it used to redirect me to random sites instead of the one i typed in.

But once i fixed the random directing site problem, looks like it decided to delete or somehow ruin my audio. I cannot click on place volume icon in taskbar because it is grayed out and when i try to instal the driver it always fails. So im stuck in a ditch and i want to get this little (or big) thing out of my computer ASAP!

I also can't get my icons and start menu to show up by themselves.

I am trying my best to get this "thing" out of my computer but i definitly need some help!
