Internet Optimizer

Internet Optimizer, also known as DyFuCA is an adware and a spyware program, which first appeared in 2003. It typically redirects Internet Explorer error pages to advertising pages. It may be installed as a drive-by download via an ActiveX component, usually via nuisance affiliate porn webpage popups. Users suspicions are lulled by its installer title as Internet Optimizer under the guise of the name of the otherwise unrelated Moneytree, while the C&C domains accessed were usually named with the prefix "mtree".
