Your antivirus sees it as potentially dangerous for your PC. Furthermore, there's an exploiter called JCE and that could also be the reason for your antivirus acting up. Unfortunately, I can't tell you whether the application you have is safe or not because I can't know where you have it from or if someone has tampered with it, but I recommend scanning the installer or the executable file using an online service called VirusTotal. It's usually very accurate when it comes to detecting threats. In case you're sure that the file in question isn't a virus, you could temporarily disable your antivirus or whitelist the program in its settings.
