thats one thing with hacks and what not, it is at your own risk. as it goes so far i havent had any issues with this.everthing i scaned it with showed nothing so from that aspect i feel its safe. plus its a open source so the program its self are wide open for any one to dig thru and see if there is anything bad put into it.
once again tho anything you download at the end of the day is at your own risk.
