Windows 10 comes with its own virus protection called Windows Defender it's
an excellent tool but you need to make sure it's switched on up-to-date and
working the easiest way to access defender is to click on the start menu
tool at the bottom left hand corner of your screen when the menu tab opens
you'll see a column of icons on the left hand side you can click the three bar
icon at the top to expand it like this you need the Settings icon towards the
bottom click it and you open the settings menu here you'll get 9 options
from system tools through to update & Security you could type defender in the
search tool here but it's just as easy to click on update & Security which
opens up the full secondary menu here windows defender is the second menu on
the list but before you click that it's important that you check to make sure
you've got the latest Windows updates you can click the button check for
updates but here the text tells me that I've got all the current updates
installed having checked this I now click on the windows defender link and
the tool opens here first I want to make sure that real time protection is
switched on it usually is by default but it's wise to check the next to slider
buttons are for cloud-based protection and sample submission I'll switch these
off until I've scanned my computer for threats defender also gives you the
option to exclude name files from the scan unless you have a good reason to do
this don't add any exclusions they provide a way in for viruses and you
don't want to leave a hole in your protective screen I like Windows
enhanced notifications tool so I leave that switched on and finally defender
gives you a way of scanning your computer for threats when you're offline
this is very useful if you've got a browser hijack or
threat that compromises your internet connection and finally defender tells
you about itself this can be very useful for technicians if you need to get extra
help now let's go back to the top of the menu an open defender by clicking this
button here if this is the first time you've opened defender it'll show you a
welcome screen telling you what's new in defender it's really just another check
to make sure you're sending threat samples to windows and we've turned this
off for now the defender menu itself should open up with a reassuring green
bar at the top with the message PC status protected and a great big green
tick in the indicator however if you get a red bar like this with a big red cross
in the indicator you simply need to turn to fender on by clicking the big red
button here once defenders turned on the next thing to do is to check that all
your virus definitions are up-to-date defender tells me that mine are but it's
worth checking by pressing the update definitions box here having updated your
definitions the final set up task is to give your computer a thorough scan I
click full-on scan options then scan now a full scan can take more than an hour
so I tend to do this before I go to bed leaving it to scan overnight once
completed defender will tell me if any threats have been detected now it's
worth doing this with the history tab because that will show you any threats
that may already have been quarantined and I got quite a surprise making this
video defender showed me that it had already quarantined a fairly severe
threat somehow I'd picked up a Trojan the defender had quarantined it for me
and I hadn't noticed now I didn't want that software bundler either so I simply
click remove all and defender destroyed all the unwanted threats finally I want
to switch back on the automatic threat submissions anything that helps windows
defeat malware is a good idea defender is a great tool and because it's
designed to fit with Windows 10 it doesn't slow your computer as much as
other antivirus tools can besides why pay for anti-virus software when window
gives you a great one for free we recommend you use it eTop Technology
