What is rogue security software?
Rogue security software is fraudulent antivirus or antispyware software which appears to be legitimate. These applications, also known as “scareware,” typically display fake virus alerts which are designed to scare you into thinking your computer is infected with viruses or spyware. These pop-ups often look very realistic, like the window pictured below, and try to lure you into updating your security software and/or running a virus scan.
What should I do if I encounter fake virus alerts?
If you encounter these types of pop-up windows while surfing the Internet, you are strongly advised NOT to click anywhere inside the alert box. Instead, use one of the following methods to close the window:
- Press ALT+F4 on your keyboard to close the current window.
- Press CTRL+ALT+DEL, open Task Manager, select the Applications tab, select the window you want to close and click End Task.
If these options don’t work, you may want to restart your computer as a precaution.
What can this rogue software do to my computer?
Clicking on these pop-up windows could trigger one or more of these undesirable outcomes:
- You may trigger the installation of real viruses or spyware.
- You may be taken to a website which tries to lure you into purchasing fraudulent software.
- Your computer may become slow or unresponsive, and you may have problems getting online.
- Allow the perpetrators of the rogue software to gain access to information on your computer.
- Allow the perpetrators of the rogue software to disable legitimate applications which protect your computer, including Windows updates and your antivirus software.
