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 If you have an out of date anti-virus program on the computer, then the virus will be able to disable it.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.
