What virus scanner told you this? It should be able to remove the offending infection it's self. You can download the free scanner "AVG" (Google it) and it should be able to help. If it still won't remove, write down the virus' name (Don't misspell) and google the name and "Remove". Assuming that the name is "tidservline," type "tidservline remove" in google and search.
