Hello and welcome. If you are like almost everybody else, and you're watching this video,
then you have a computer and use it on the Internet. In using your computer on the Internet
you expose yourself to viruses, spyware, and other malware. This malicious software intends
to infect your computer to steal your personal information, try to sell you stuff with pop-ups,
or just slow your computer down and cause mischief. For the longest time the only option
to protect your computer was to purchase antivirus software such as McAfee or Symantec for a
yearly subscription fee. More recently antivirus programs like "AVG antivirus" and Avast have
offered pay for full-featured versions as well as free versions that have fewer features.
Now Microsoft has finally created their own antivirus program called "Microsoft Security
Essentials" that offers comprehensive protection against spyware, viruses, worms, trojans,
and other malicious software. It's very easy to use and integrates with "Windows Update"
to download and install the latest definition files. To install Microsoft security essentials
open "Internet Explorer" or another web browser like Firefox or Chrome, and go to Google.com.
In the search field type in "Microsoft Security Essentials". This link may change over time,
but for now it is "http://windows.microsoft.com/en-US/windows/products/security-essentials". Click on this link. On the "Microsoft Security
Essentials" home page, click the "Free Download" button. You will be prompted to either save
or run the file. Click "run". After the download finishes if you have "User Account Control"
turned on you'll be asked if it's okay for this program to make changes to your computer.
Click "Yes" on the "Welcome to Microsoft Security Essentials Installation Wizard" screen. Click
the "Next" button. On the "Microsoft Security Essentials Software License Terms", read the
license agreement, and then click the "I accept" button. On the "Join the Customer Experience
Improvement Program", click the "Join the Customer Experience Improvement Program",
this will send some basic information to Microsoft to help them improve the product, and click
the "Next" button. On the "Optimize Security" screen, leave the defaults, and click "Next"
on the "Ready to Install Microsoft Security Essentials" page. Click the "Install" button.
On the "Completing the Microsoft Security Essentials installation Wizard" screen it
will tell you if you have successfully completed the installation or not. By default the "scan
my computer for potential threats after getting the latest updates" is checked. Unchecked
this as we'll do this manually, and click the "Finish" button. After the installation
is finished its first step is to connect to the Microsoft servers and download the latest
definition update files. The definition files provide information to Microsoft Security
Essentials on how to detect and remove all known viruses. Once the definition updates
finish installing it brings you to the home screen of the Microsoft Security Essentials
window. This is the main window of the newly installed application. Notice in the bottom
right of the screen in the system tray that there is a new green icon with a white check.
This is the Microsoft Security Essentials application that will monitor your system
at all times. If it's green everything is good, if it changes color to red there is
a problem that needs attention. When the application is closed you can open it again by double
clicking on this icon. Click on the "Settings" tab. By default it is set to run a scheduled
scan on my computer Sunday night at 2 AM. It is set to run a "quick scan". Let's change
this to a "full scan". A full scan scans every single file where as a quick scan only scans
the most commonly used files. Make sure that the time set for the scan is when the computer
is going to be on, and if possible not in use. Change the default time as needed. Click
on the "save changes" button. On the "User Account Control" window that pops up click
the "yes" button. To allow Microsoft Security Essentials to make changes to your system,
click on the "history" tab. Any threats detected over time will show on this screen. Click
on the "update" tab. You'll get the latest definition updates once a day. If you want
to update manually, just click on the "update" button. Back to the home tab. Let's run a
full scan on our system by clicking the radio button next to "full" and click the "scan
now" button. Depending on how many files you have on your system the scan could take quite
some time. Now that the scan is complete i'm going to run a test virus to show you how
to remove a problem if it is detected. You do not need to follow this part. I will browse
to www.EICAR.org. Click on the "download anti-malware test file" link. Scroll down and select the
text in the box, right-click, and select copy. Minimize everything, right-click on the desktop,
new "Journal Document". This will be changed so it really doesn't matter what file type
is selected. Rename "testvirus.net". Click the "yes" button to confirm you want to change
the file extension. Right-click and select "edit". Right-click and paste. Click the file
menu save. Close the window. Now without even having to run the file Microsoft Security
Essentials has detected it as a threat. Click the "clean computer" button. We can see the
EICAR test file here, the action is to remove it. Once a file is successfully removed click
the close button.
