Is anyone familiar with Virus Melt?

My computer was infected today with Virus Melt.  It causes pop-ups that list bogus alerts stating my computer has been infected with viruses.  Can anyone offer a way to remove Virus Melt?  I’ve verified that my Norton definition file is up-to-date and I’ve run two complete scans.  Norton isn’t picking-up Virus Melt.  Many thanks.
