what is a scareware

Scareware is a type of malware designed to trick victims into purchasing and downloading useless and potentially dangerous software.

Scareware, which generates pop-ups that resemble Windows system messages, usually purports to be antivirus or antispyware software, a firewall application or a registry cleaner. The messages typically say that a large number of problems -- such as infected files -- have been found on the computer and the user is prompted to purchase software to fix the problems. In reality, no problems were detected and the suggested software purchase may actually contain real malware. If the user falls for the scam, he will lose the money he paid for the useless software and he may also make his computer unusable. Frequently, the message window has a clickjacking feature that takes the user to the attacker's Web site or initiates a malware download if the user clicks "Cancel" or the "X" to close the window.

If you encounter a suspicious pop-up, you should right-click on the item in the task bar and select "Close" or manually exit the browser by clicking Ctrl-Alt-Delete. To protect your system from future attempts, install a good pop-up blocker and configure it to prevent pop-ups from sites other than those that you specifically allow. via.
