Some people may have
heard of scareware and may have a basic idea of what it is. Most, however, will
not know exactly what it is and how exactly it works.
Scareware is a type of
malware that pretends to be a real anti-virus program. It appears in a pop-up
window on your browser and is designed to look and feel like a Microsoft
program, to fool the user into believing it.
The pop-up will always
show many infections that need to be repaired and will offer to do so. However,
when you press 'OK' or any other button that agrees to let the program do its
work, it instead installs the main scareware program on your computer.
In fact, even pressing
the red 'X,' or anywhere else in the window will install it. The only way to
prevent it from being installed is too close the browser completely and start
an entirely new session when you reopen it.
Once you have the
original scareware program installed on your computer, it will prevent you from
doing anything that you normally would in order to fix an infection. If you
have an out of date anti-virus program on the computer, then the virus will be
able to disable it.
The scareware will
also perform what is known as browser hijacking. A hijacked browser will often
not go to the addresses that the user inputs to the URL bar. The browser
instead redirects the user to only pages that the scareware allows them to see.
This means that when
the user runs a search for how to remove the scareware or searches for an
anti-virus program, all that they are able to see is more malware or other
rogue programs designed to look legitimate.
When they download,
and install something to try and clear the infection, they end up installing
more malware. If the scareware demands that the user pays a fee in order to
remove the viruses, and the fee is paid, the viruses will remain, and the
scareware will continue to lock up the system.
Antimalware programs
are the best and most certain way to rid your machine of these malware
programs.
Scareware can be
tricky to remove from a computer. It can be done, but ultimately the best
offense is a good defense. Installing one of the many paid anti-virus suites
such as Norton, or the free ones such as avast antivirus and then keeping them
up to date is the best way to protect your computer.
Beyond this don't
click links that you can't trust 100% and never trust a pop-up that tells you
that you have a virus!
