Remember the time when you are browsing and
suddenly pop ups start appearing out of nowhere, you get e-mails from unknown
sources asking you about renewing your software that you never installed. Your
search starts redirecting you to unknown websites and seems like irrelevant.
You have drastic drop in your system performance. All these indicate that you
have a spyware in your system. Beware it is dangerous to your system and the
data that you have. If only you knew how it entered your system, could you have
avoided it in the first place? Now the question is how did this happen exactly.
Spyware enters your system when you click a
pop up window, install a software or even while you agree to a policy or adding
a function to your browser unknowingly. There are applications that use these
methods like generating fake alert messages of virus or malware attack and even
pop ups with cancel button. As soon as you hit the cancel button, a spyware is
installed in your system unknown to you.
Browser add-ons
While looking for add on tools for your
browser there are numerous choices available online. A tool bar, software
enhancement, additional search box and other such plug ins are often a few of
the examples of spyware. Additionally, these can hijack your browser once you
install these. Another thing to remember is that these are not easy to get rid
off, as these get embedded in your system and hard to detect and remove.
Drive-by download
This is the most common method to deploy
spyware in your system. Usually a website or a pop up window will automatically
download a spyware on your system. You will be prompted with a message from
your browser seeking your permission to install it. However, often even this
message does not appear in the lack of security settings.
Masquerading as anti-spyware
This is a hidden trick that is often used to
install the harmful software in your system. Often you will get an alert
message that says installing a tool will help you detect and even remove
spyware from your system. As soon as you run it on your system to remove it,
the software instead gets installed.
Piggybacked software installation
This includes applications where you share
data online or exchange files. For example free file sharing software and peer
to peer, this acts as a gateway to spyware. Here you need to be careful about
the installation list that contains installing spyware in your system. The
file-sharing application contains more than what you have asked for. Beware of
free versions that are advertised as alternate version to the software that you
are looking for.
