How to turn on Windows Defender in Windows 8
Hi everyone in this article I’m explaining about windows
defender in windows 8.
Microsoft acknowledged the growing threat of spyware with
the launch of Windows Defender a few years ago. It’s available for Windows XP
through to Windows 7. In Windows 8, which is the most secure version of the OS
so far, Microsoft provided an enhanced version of Defender which also protects
against malware – effectively rolling Security Essentials and Defender into
This rubbed all the security software companies up the wrong
way, so Microsoft provided an option to turn off Defender when a trial version
of a security suite was installed on a new PC or laptop – it’s bad practice to
run more than one antimalware engine at the same time. They will probably
conflict with each other and cause severe performance problems.
However, should you decide not to activate that McAfee or
Norton trial, Defender won’t automatically enable itself again, so you’re left
unprotected from the viruses, Trojans and other nasties that could play havoc
with your system, and even leave you out of pocket.
It’s easy enough to check if Defender is running: simply
look for its icon in the Notification area (the space to the left of the clock
to the right of the Taskbar). It might be in the list of hidden icons, so click
the little upward-pointing arrow and look for a castle icon.
Don’t worry if you can’t find it – it may still be running,
or your computer might already be running other security software which is
doing a similar job. However, if you’re still not sure or you know your
computer definitely doesn’t have an antivirus program or security suite, here’s
how to enable Windows Defender.
In the Start menu (or on Windows 8’s
start screen) type Defender. Windows Defender should appear in the list. Click
on it to launch the program. If it’s already running, and you see the main
Step 2: You
might see a message like the one below, showing that Defender is turned off and
isn’t protecting your computer. If so, search for Action Center in the Start
menu (or screen if using Windows 8) and run that.
Step 3: In
Action Center, click on the Security tab to check which program is handling
spyware and unwanted software protection. If you want to enable Defender in
place of another suite such as McAfee, you should use the Control Panel to
uninstall that first.
Step 4: When
that’s done, type Defender again in the Start menu and, if it’s turned off,
you’ll see a message and a link to turn it on. Click it to turn on Windows
Step 5: Assuming
your computer isn’t protected, the Windows Defender main window will open on
the desktop. Chances are, the spyware definitions will be out of date, so now’s
the time to update them. Click the Check for Updates button.
Step 6: When
that’s done, you should see a nice green bar showing that Defender is up to
date and protecting your computer.
Step 7: Click
the Tools link at the top, and then on Real-time protection in the left pane.
Check that it’s enabled and then choose options for scanning downloads,
attachments and programs that run on the computer. We advise enabling all the
As mentioned at the beginning, in versions of Windows prior
to 8, Windows Defender does not scan for viruses, so ensure that your computer
has some antivirus software installed.
