From time to time, you may encounter a website displaying a warning page similar to the image below. It may be on a commercial website or possibly even a site you have created using a third-party hosting company.
Lehigh LTS subscribes to a number of malware filtering services to aid in the cyber protection of our users and of our network. This warning page indicates that the site you were trying to view has been placed on a ban list by one of these filtering services as having found malicious content which may be harmful to your web browser, your computer, or the network.

You will only see this warning page for sites being accessed on Lehigh's secure networks, that is, the 'lehigh' wireless network and our physical (hard wired) network. If you need to connect to a blocked site, you can still connect to our less secure 'lehigh-guest' wireless network, or connect from an off-site ISP or data connection and it will allow you access to the site to view the content. Just be aware that if the cause of the ban was malware, you may be opening up your browser and/or computer to possible infection.
