99% chance it's not safe and will do other things than just autoclick
hMM ok thanks for the reply, what could be the other things is does than just autoclick?
anything really...
it could snoop for files containing keywords (such as wallets, etc).... it could mine on your CPU without your knowledge... it could do a LOT of things.
I would run it in a sandbox. If you run it in a sandbox, it is rather limited. Use a Hyper-V or oracle box VM. Load windows 7 on it. Run it under a user account that has basic and non-admin privileged. Only let the virtual network adaptor see the internet via NAT on the host machine, and not be assigned an IP by the network itself. be sure the machine and network you are running this on is separate from anything you hold dear... like your home network, file shares, router, etc. Be as safe as possible when it comes to random crypto concerns; especially brand new people trying to get you to use their thing because reasons like "blah blah blah".
Keep it 100% separate from anything you care about; including personal account info. Create new payout addresses specifically for use with the faucets only, etc.
mind you, this is an application; I have been able to prove that I can control and download/upload files on a persons machine easily just from a batch file that has been executed on the host machine (my batch can update itself over the net on my command or by a version update as a prime example). An application can make use of countless other possibilities compared to my "dos level batch files".
