PLEASE NOTE: We have recently discovered that some less sophisticated virus scanners such as Microsoft Security Essentials flag our software as containing a virus or malware and can possibly delete F-Intermod from your computer after installation. We want to assure you that our software does not contain any viruses or malware, and does not connect to the Internet without your knowledge. Other more sophisticated virus scanners work well with our software, such as AVG. If this occurs on your computer please set your virus scanner to ignore F-Intermod. See here for purchasing information.
