Antivirus Pro 2009

My daughter went to a website that gave her this malware…I would prefer not to buy yet another software package to get rid of it. I have tried manually uninstalling it (wiki-security.com) but it has mutated its registry values and executable names so that source (wiki-security) is no longer current. Will avast ever deal with this? How do I get rid of it?
