Security Exposure - it's your behaviour, not your system
Along the lines of the new theory of child-raising, where you teach that "Stranger" is a behaviour, not a person, I saw today this blog posting from the Microsoft Antimalware team.
It highlights that in a recent analysis of the results from the (Malicious Software) (Removal Tool)(*), the most frequently detected piece of malware by far ( more than 6 times ) is a Trojan that pretends to be a crack for various popular software, and makes itself available on various P2P services.
If there's a system that is vulnerable to this exploit, it's the human central nervous system. Layer eight. Between the chair and the keyboard.
If you're getting infected by this, I have one question - why are you killing your system?
Here's a (loose) definition of malware: untrusted code from unknown people.
Here's what you download and run when you get cracks from p2p networks: untrusted code from unknown people.
Oh, and to join in another argument that's raging right now, "untrusted code from unknown people" can also describe what you get when you install unapproved patches by parties other than the vendor / developer of the code that you're patching.
Practice safe hex. Always get your software from a trusted dealer, and don't try to skimp on the cost of the software.
