1212This security alert appears while you are working on your Windows computer. What should you do next?

Do not click the buttons! This is a kind of hoax. Either button you click will cause negative consequences, such as the installation of malware on your computer. Attackers are quite skilled at making their pop-ups look like legitimate security alerts. Shut down your computer, and when it restarts, run a virus scan or boot with bootable media provided by your antivirus company if possible.
