| The point is that most applications need more administrative rights to be installed. When they subsequently run they run in user mode.
When you are installing an application you are verifying that you are happy for that application to install on your machine because you trust it. Therefore you click accept on the elevated privs dialog to give it full rights to install.
If you are surfing the net or using your email client and you accidentally download some mal-ware or trojan etc, it tries to install and it can because it has no access, the elevated privs dialog pops up and asks you do you want give it elevated privs to install, and you say no way! Then it can't install.
The risk is if you press the accept button on the dialog (and even then there is a secondary prompt) the trojan or whatever installs on your machine with full rights, but this isn't really any different to XP/2000 previously if you are running as an administrator. |
