What Norton, McAfee and Microsoft won't tell you.
The main problem with Windows computers is that most people run them
with Administrator privileges. This means that if they want to install
software, change system settings etc., they don't have to enter a
password, they can change anything they want. This is very convenient,
and it is the default setup that Windows encourages, but it is a major
loop hole that almost all viruses, trojans and spyware exploit, because
the virus also has administrator privileges over the machine.
Many people rave about the excellent security and stability of Linux
machines, and rightly so, they are a great system. But users of Linux
machines usually DO NOT run as administrators and if any system settings
need to be changed, or software installed, it is required to enter
the administrator password. This effectively locks viruses out of
all the system files and folders because the virus does not know the
administrator (called "root" in Linux) password.
Wouldn't it be nice if Windows machines could be set up in this way.
You could surf the web and do all your daily tasks with normal restricted
privileges and if you need to install software or change your network
settings, you log in as admin, enter your password, do your stuff,
log out, and log back in as yourself.
Well, you can set your pc up like this.
Below are instructions on how to secure your Windows XP/2000 machine
(sorry Windows 98/95 users can only follow the first 3 topics):
Get an Antivirus program
That's it. Now when you want to install some software
just log in as "admin" do your stuff and log out. Now when
you surf the web, viruses won't have administrator privileges over your
