content: AV is shit. I have an idea, let's let this piece of software I trust for some strange reason get its roots deep into my operating system with full administrative privileges.  It won't do anything bad, it promises!  It's there to be your friend! No thanks, I don't have that level of trust in any software.  When it comes to computers you pretty much need to take the James Bond approach: Trust no one. I use Linux, and you know what?  The source code involved in all the massive bits is immense.  There's no way one person could audit it all every time new versions of each component came out for bugs and security exploits (either accidental or intentional). With the shit that the NSA has been doing as of late, you'd be naive to trust any of it.
