Yes they are. I had the same thing going on for one of my sites, where I'd see these fake sites in the SERPs with MY meta descriptions, and I'd go to the page and it was either some virus scam or else a parked page designed to look like a Google (or other search engine) results page. Looking at the source, my description didn't show up. They also took my titles. These were not outranking me, but they were showing up high enough for some long tail searches, to the point where I was worried some of my users would be confused and click on the wrong things. It was some kind of crap network of sites originating overseas, and I made enough of a stink about it that eventually I was contacted by Google for details, and shortly thereafter they disappeared. Google doesn't like to look stupid.
These are definitely a scourge, and it's bad enough that they exist, but they shouldn't be outranking you. If they are, then I suspect it's a separate issue.
