Many Anti-Virus programs are going to falsely identify files. Most of the programs will allow you to add the file to a trusted list. This will tell the Anti-Virus program not to identify the file as a threat. If the file is a POTC program file, it is seriously doubtful that it is infected unless something else got into your PC and replaced/infected the original file. I have never heard of a true infection in regards to any POTC files.
