I second what Porktown stated.
I uninstalled Chrome and IE and downloaded a fresh install of Firefox to work from.
I downloaded and ran fresh updates of Malewarebytes, CC Cleaner, Spybot Search and Destroy, updated Avast and Superantispyware.
Only Malewarebytes and CC cleaner saw it. After I cleaned it up, I reinstalled Chrome and IE and was rid of it.
I also had a holdpage.pup that came along with it that I had to clear up too.
I ran a search for the Vosteran files and the holdpage.pup files on the C: drive and deleted what I could find but had to run MB and CC Cleaner to get rid of it all.
