The 'Important Message' pop-up is a fraudulent system alert that may initiate a range of diverse attacks, as well as encouraging contact with con artists. Although the 'Important Message' pop-up formats itself as a security warning, the 'Important Message' pop-up offers no benefits to your PC, and even casual interactions with the 'Important Message' pop-up may run the risk of harming your computer. Sites that promote the 'Important Message' pop-up should be assumed to be toxic, and malware experts recommend using anti-malware tools to disinfect any PC that loads the 'Important Message' pop-up non-consensually.

The Importance of not Ignoring an 'Important Message' pop-up

The 'Important Message' pop-up is a pop-up window-based attack that subverts your browser for the purpose of enabling one of a multitude of tactics. Malware experts have connected some formats of the 'Important Message' pop-up to DoctoAntivirus, a rogue anti-virus scanner, but other variants of the 'Important Message' pop-up may launch attacks. The most common payloads linked to an 'Important Message' pop-up may include:

  • An 'Important Message' pop-up may install fraudulent security products that pretend to offer anti-virus, anti-spyware or anti-adware services. This scamware typically blocks other applications and generates more fake alerts until you pay its registration fee.
  • In other cases, an 'Important Message' pop-up may try to lead you to contacting a con artist, such as a fake PC repair technician. Phone-based contact is the most common, but not necessarily exclusive format for such interactions, which may try to create new vulnerabilities on your PC or take your money.

Intentional interaction with an 'Important Message' pop-up is not necessarily the only means by which an 'Important Message' pop-up may harm your PC. Malware experts also see the 'Important Message' pop-up and other pop-up-based attacks using automatic scripts that may trigger without any extended interaction. Java, JavaScript, and Flash are the three most common formats of the forms of these invasive PC threats.

Stopping a Pop-Up Message from getting the Best of Your Browser

Mozilla's Firefox has been a party to the majority of verified attacks through an 'Important Message' pop-up. However, other brands of Web browsers may be just as vulnerable to such attacks, which may launch themselves through a pre-installed adware program or a compromised website. Browsers that launch an 'Important Message' pop-up repeatedly are likely to be compromised, requiring that you disinfect your PC with an anti-malware product, anti-adware scanner or similar tool.

On a greater scale, the 'Important Message' pop-up is significant only in its continuing use of social engineering to trick its victims into harming their personal computers. PC users never should take security advice from websites with unconfirmed identities, and should learn to identify legitimate system alerts and sort them from threats like an 'Important Message' pop-up. Learning the proper responses to such attacks also could prevent an 'Important Message' pop-up from introducing new threats to your machine. However, preventative security steps and appropriate browser behavior are the two things malware experts always would emphasize the most for stopping a fraudulent browser pop-up.
