I downloaded a file and the file was a virus but my avast protected me from most of it. I say most of it not all of it because when i am on Google chrome and i go to a site it starts to load the site then just switches over to some ad each and every time. I've already run a full computer scan with avast and its still happening only some sites when clicked will actually go to the proper site while the others don't. Is there anyway to fix this problem so i can surf the internet without any hindrance?
I am running Windows 7 home premium edition.
