Additional Security Resources
Many sites and services on the Web can help you learn more about computer security threats or can analyze your machine to make sure it is clean and safe.
Hoax Encyclopedia: The About.com Antivirus site has a comprehensive database of e-mail and virus hoax messages. Before you forward the next "urgent" alert to your family and friends, check for it on this list.
McAfee Virus Information Library: McAfee maintains a complete listing of malware threats, including details on how they spread and how you can protect your computer against them.
Microsoft Consumer Security Support Center: On this page you can find solutions to common security problems, as well as links to other information and resources for Microsoft's security products.
Microsoft Malicious Software Removal Tool: This tool is designed to scan for and remove current, pervasive threats. Its scan is smaller and faster than a complete antimalware scan, but it identifies only a handful of threats. Microsoft releases a new version of the tool--along with regular security fixes--on the second Tuesday of each month ("Patch Tuesday").
Microsoft Security Essentials: This free antivirus application provides real-time protection for Windows PCs against viruses, worms, spyware, and other malicious software.
PhishTank: A community project, PhishTank is a database of known phishing sites. You can search the database to identify phishing sites, and you can add to the list any new sites you've encountered.
Trend Micro Housecall: Trend Micro's free HouseCall service scans your computer online to discover and remove any viruses, worms, or other malware that may be residing on it.
