Always.Actually there are a few times when auto updating your software of virus definitions is a good thing. That is usually limited to when you are talking about “top 100” type vendors. For example I do not mind auto updating anything from Apple, the AppStore (Mac or iPhone), and I do not mind many of the software vendors that have been around for 10+ years and have a solid reputation. And I generally accept MacPorts.But then this one caught my eye.I started off by thinking that this was going to be an easy install of what looked like a decent application/script. The script was going to tell me everything about what programs and processes were connected to the outside world. (Kinda like little snitch) But as I read more of the online documentation I saw that a) it was from a college; and b) it was going to autoupdate.I was a college student once and I did not do anything really stupid when I was that age but not everyone is like me that way. But I was incredibly curious and if I had today’s tools would I have been that nieve or straight. While this shell script looks interesting I’m not going to install it out of general fear.PS: they could have installed the script in userspace. They did not have to request the admin password.  And for those of you that did not understand the above… just think about trojan horses and what lay inside. Computers are cheap enough… I just cannot afford the time required to rebuild one from the ground up.
