Every time I scan my PC for virus', Auto Xbins comes up as a threat (Avast! & MalewareBytes') I can assure you that it is not!
I remember back in the day when you had to go to specific IRC channel and request a username and password. Then you would enter the provided user name and pass into either Flash FXP or Filezilla (or whatever FTP program you happen to be using). Then, you only had a certain amount of MB's you could download before you were booted for the day.
Somebody, I can not remember who, developed "Auto Xbins". It's a tool just like am FTP program that gets you in automatically. Sometime it gets you in really quickly, other times it takes a few try's. For what it's worth, this tool saves newer users a whole lot of hassle.
A updated tool previously known as Easy-Xbins.
This tool will provide you with fast, easy 1-click access to the Xbins FTP service where you can download the latest homebrew and hacks for the Xbox, Xbox 360, PS3 and the Wii
Save the exe to your desktop, or to an easy to remember location. then just double-click it whenever you need access to Xbins. You will be logged into the ftp within seconds, with zero effort!
