It's always on your side when your antivirus program blocks it. It doesn't mean anything is wrong with it. Every program has the potential to alter your computer in a negative way. A virus is just a normal program that's been made to do harmful things to your computer. Antivirus software doesn't like programs from unknown publishers. You just have to add it to your trusted list.

It only blocks it because the publisher is unknown. it should be safe
