If you experience sudden performance issues with your PC and notice pop-ups asking you to dial 866-933-5430 for help, you are certainly infected with a cyber threat. These notifications are not reliable. If you agree to call this number, you will not get in touch with experienced technical support agents who can help. Instead, you will talk to con artists who may introduce themselves as experts. They may try to charge you a fee for their bogus services. In some cases, this tactic may result in severe financial losses. The con artists may encourage you to share your credit card details with them, which will allow them to operate with it without your permission. Moreover, the fraudsters may demand remote access to your PC, which they may use to install information-collecting threats. The harmful application that displays the 866-933-5430 pop-ups may enter if you download questionable programs like VMC Media Player.

The infection also may occur if you open corrupt email attachments or install updates for Java/Adobe from unverified domains. Tactics like this one may happen when the PC user's Web clients get compromised by a browser hijacker. Unfortunately, the case with the 866-933-5430 warnings is an exception to the established rule. The harmful add-ons cannot cause any issues outside of applications like Google Chrome, Mozilla Firefox and Internet Explorer. The threat related to the 866-933-5430 pop-ups, on the other hand, may affect various sectors of your Operating System (OS). The cyber threat may cause freezes, crashes and other bugs. It also may lock your screen and make it impossible for you to perform any actions besides a restart. In some cases, the harmful program may even bring the Blue Screen of Death (BSoD). It is advisable to delete this parasite with a powerful security utility.
