Browser hijacking or 'pop-up phishing' involves fraudulent messages that unexpectedly pop up for users when they are surfing the web. In many cases, cyber criminals infect otherwise legitimate websites with malicious code that causes these messages to appear when people visit them.
The content of these messages themselves is what makes them so effective. Often, they present the unsuspecting website visitor with some kind of fraudulent warning from a well-known reputable company, typically about the security of their computer. Then they either prompt the visitor to download some tool to fix the problem, such as an antivirus application which turns out to be malware itself, or to call a fraudulent phone number for "support." The abnormal behavior of the message itself and the inability to close or navigate away from them, makes the fraudulent messages appear to be somewhat credible.
This guide will demonstrate how to rid yourself of the worrisome pop-up message, and then perform some simple operations to get Microsoft's Internet Explorer back to normal.
