For hacking a site or computer there are needed two or three elements: 1) To upload some code. 2) Change the code file to executable mode (Only Unix style OS), for Windows this doesn't exist at all. 3) Execute the code. Step 1: Can be done by a hacker. Step 2: Only can be done by a person with supervisor priviledges access to the computer, a hacker haven't these priviledges. Of course that this step on security doesn't exist in Microsoft universe. Step 3: You must execute the code, for executing the code you must have access to the computer, a hacker has not the access, he need to execute the code first to obtain access. Of course that Microsoft solved this problem for the hacker and IE, Outlook, Messenger can execute a code remotely in your computer without your knowledge, but this only happens in Microsoft's world, in secure systems this is never allowed.

Stupidity also evolves!
