How to get rid of a virus that causes pop-ups that I have deleted?

I got a virus from the program "PlusHD" which gave me tons of ads. It even disabled the function of Google Search, and if I do that, my Chrome goes 100% unresponsive whatsoever. Please help - I deleted the virus, scanned it with AVG, and still terrible. I even used TuneUp, which usually gets rid of all problems. Still, virus still there. How do I retrieve this file, so I can get rid of it, or how do I get rid of this even if it's so-called "deleted?" I need help - I can't even search for how to install Minecraft. Oh, yes that was just a test. Help please, it will be much appreciated.

*P.S. Ignore that last question, my account was messed up by my brother.*

Well that is hard…
1) Go to the store you bought your computer off of then have them get rid of it… Sadly you can do nothing to get rid of it

It is NOT a Virus. It is AD-Ware. A type of Spy Ware. Not all bad things are a Virus.
