"Windows Security Alert" is a rogue pop-up that closely mimics those of familiar Windows tools and usually shows up after a minute of fake scanning activity. It could easily fool casual users into thinking that the alert was real. A dialog from a web page labeled Windows Security Alert that reports tons of infections is suspiciously generic. Besides, it looks like a local security message and that doesn't make sense because a random webpage can not know what is installed on your computer. If you encounter any suspicious webpage dialog, the correct procedure is to immediately close your web browser. If you can't dismiss it via the "X" close button then use Windows Task Manager to close the browser.
Some people say it's a fake Windows Security Alert virus but actually it's not a virus, not even close to a real virus. It's just a fake scanner or warning that reports a huge number of non-existent viruses and security problems to make you think that your computer is infected. Over the years, the crooks began to use a variety of fake online scanners and fake warnings labeled "My Computer Online Scan", "Windows Web Security" and "Windows Security Alert" to trick casual Internet users into installing rogue security software, Trojan horses and other malicious software. If you've installed rogue security application or other malware from such a misleading web page, please run your favorite security tools or the ones listed below. Malware like this is easy to avoid, if you pay attention to what's going up on your screen. If you have any suspicions at all, dismiss such fake pop-ups as "Windows Security Alert" at all.
