My mother-in-law is receiving popups that she has viruses, trogans
etc... on her computer and the only way to remove these files is to
purchase a product called Malware Catcher 2009 (also as a popup). She
has Norton installed (and recently purchased an upgrade) and they want
to charge $100 to remove the software. Has anyone had any experience
with removing this PUP (just learned this term potentially unwanted
programs)?

Thanks

Steve
