Some users have complained that they have been repeatedly displayed an Important message pop-up window claiming that their PCs have been infected. The Important Message window is not to be trusted as it is a part of a fake tech support campaign. The potentially unwanted application responsible for the Important Message pop-up is likely to have entered the system through a bundled download. Another option is the execution of a fake software update.
Users should not forget that valid software updates do not come in the form of pop-up windows, e-mails, etc. They are executed by development and security themes without the need of the user’s interaction.
Important Message Pop-Up Description and Distribution Path
- The display of the message is probably triggered by an ad-supported extension. Such third party browser-targeted software is usually written to be compatible with widely used browsers (Explorer, Firefox, Chrome). Once installed, the PUP behind Important Message Pop-Up may alter both the browser and the system settings so that manual removal is difficult for non-expert users.
- A popular distribution technique for software of the kind is bundling. Bundling is mostly used to cover financial losses and to monetize various platforms. Simply avoid bundling by systematically opting for the advanced software installer to uncheck unwanted applications.
- Important Message pop-up may try to lure users into calling a fake tech support line. Beware that calling the number will not only charge the user a solid amount of money, but will endanger the user’s safety. Remote access may be granted to the cyber crooks behind the scheme to leave a backdoor for Trojans and spyware.
