qvo6 how can i remove

Hi guys somehow this virus got into my PC, there were no warnings or alerts from avast. I only noticed it when my home page changed and now i can’t fix it. I have to pay my rent but google says it can track my details and take my money if i log on ?
I did a full scan of my PC it took 13hours and it didn’t show up, 7 other threats were found but i can’t seem to send them to the virus chest, i press the green button it thinks for a minute or so then just goes back to green again ?
Any clues how i can solve this issues?
Cheers Joe
