Every time I turn on my Mac, my Zipeg program opens up and asks me if I want to extract a file called "SafeConnectMacInstaller". It just happened a few weeks ago, but I don't know how to get rid of it. I tried extracting it but it still shows up every time I start my Macbook. I don't want to install it because I'm not sure what it is or where it came from. Any advice?
