I wish all my security apps were as dependable as Nod32. Once installed, it does exactly what it is supposed to do. It updates itself frequently. It runs a scheduled scan when it is supposed to. It blocks malware like it is supposed to do. It removes malware (when infrequently one slips in). It does not bog my system down. It runs quietly in the background--doing what it is supposed to do. If I sound like I love Nod32, I do.
