This regsvr32.exe was listed on my scan using your software. It states that the file is not digitally signed however it appears to be a Microsoft product? My file on a Vista machine and is located at C:\Windows\System32\ and reflects a size of 14KB. This is the only listing of this file from a search of the system. Does the digital signature that is missing and the file size difference have any implications or am I paranoid?
