What is phishing?

Online phishing (pronounced like the word fishing) is a way to trick computer users into revealing personal or financial information through an e‑mail message or website. A common online phishing scam starts with an e‑mail message that looks like an official notice from a trusted source, such as a bank, credit card company, or reputable online merchant. In the e‑mail message, recipients are directed to a fraudulent website where they are asked to provide personal information, such as an account number or password. This information is then typically used for identity theft.

What is malicious software?

The terms malicious software and malware refer to programs that pose a security or privacy risk by demonstrating illegal, viral, fraudulent, or malicious behavior. For example, viruses, worms, and Trojan horses are malicious software.

What is SmartScreen Filter and how can it help protect me?

SmartScreen Filter is a feature in Internet Explorer that helps detect phishing websites. SmartScreen Filter can also help protect you from installing malicious software or malware, which are programs that demonstrate illegal, viral, fraudulent, or malicious behavior.

SmartScreen Filter helps to protect you in three ways:

  • It operates in the background as you browse the web, analyzing webpages and determining if they have any characteristics that might be suspicious. If it finds suspicious webpages, SmartScreen will display a message giving you an opportunity to provide feedback and advising you to proceed with caution.

  • SmartScreen Filter checks the sites you visit against an up-to-the-hour, dynamic list of reported phishing sites and malicious software sites. If it finds a match, SmartScreen Filter will show you a red warning notifying you that the site has been blocked for your safety.

  • SmartScreen Filter also checks files downloaded from the web against the same dynamic list of reported malicious software sites. If it finds a match, SmartScreen Filter will show a red warning notifying you that the download has been blocked for your safety.

Use of SmartScreen Filter is governed by the Microsoft Service Agreement. For more information, read the Microsoft Service Agreement online.

What does it mean when I see a message that asks: "Are you trying to visit this site?"

Internet Explorer displays this message when a suspicious website has some of the typical characteristics of an unsafe website, but is not on the list of reported unsafe websites.

You can help Microsoft evaluate this website by providing appropriate feedback using the links provided in the message.

What can I do to help protect myself from online phishing?

Here are some quick tips that might help protect you from online phishing:

  • Be defensive about your personal information.

  • Navigate to trusted websites by typing the web address directly into the Address bar.

  • Never give out personal information in an e‑mail, instant message, or pop-up window.

  • Do not click links in e‑mail and instant messages from strangers or any link that looks suspicious. Because even messages from friends and family can be faked, check with the sender to be sure they actually sent the message.

  • Only use websites that provide privacy statements or information about how they use your personal information.

  • Routinely review your financial statements and credit history and report any suspicious activity.

  • Keep Windows and Internet Explorer updated. For more information, see Get security updates for Windows‍‍.

What can I do to help protect myself from malicious software?

  • Turn on SmartScreen Filter.

  • Keep your computer's software updated and current. Both your operating system and your antivirus program should be updated on a regular basis.

  • Only download software updates from reputable sources. For Windows operating systems, use Windows Update. For other software, always use the legitimate websites of the company or person who produces it.

  • Always think before you install something, be sure to weigh the risks and benefits, and be aware of the fine print. Does the lengthy license agreement that you don't want to read conceal a warning that you are about to install malicious software?
