Thanks for your interest in Friture! Sorry about that antivirus alert. "FileRepMalware" means that your antivirus could not evaluate the reputation of this package, because it is not signed. It does not actually contain any malware. Unfortunately, we do not produce signed installers for now, simply because getting a signing certificate costs money.
This is the very same program, but it is verified and signed by Microsoft, so your antivirus should be happy about it.
