This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Punch "remove smart data recovery" into your favorite search engine and you'll get tons of hits on pages like this one that explain how to remove it. – David Schwartz May 1 '12 at 6:02
Try what is suggested there, too. If that didn't work, please report back. – slhck May 1 '12 at 8:23

Remove smart data recovery like what David Schwartz have said. Then install one of the popular free anti virus such as AVG, Avria, Avast, etc.
