We are happy to help parents or kids check a link or file for known threats. If you have a link or file you are concerned might be unsafe, you can use this form to send it to us for analysis. We check these as quickly as we can, but please allow a few days for us to get back to you.
If you need an answer more quickly, Google has a very good service that will check a site for safety.
Virus Total is another good online tool for checking websites and will also scan files for you.
