    Smart Defrag is not malware, a parasite or virus. It is a legitimate disk defragmenter that I have been using since its 1.xx days. Its also one of the best free options available. HOWEVER, it does have its problems. It is not fully compatible with all OSes/versions/updates. It also has difficult to remove files, such as the Smart Defrag Homepage.
