What is You Shall Not Pass?
The "You shall not pass" message appears when attempting to access Google, Facebook, or other popular websites. It is a host hijacker - a security infection, which modifies the operating system Hosts file. This file is used to resolve canonical names of websites to IP addresses. When this file is modified, users may be redirected to malicious websites whilst still observing valid URLs in address bar. Note that this particular security threat does not appear to be especially malicious - it blocks access to popular websites, however, it does not perform other malicious tasks. Other Hosts file hijackers prevent users' access to the Internet, then coerce them into completing online surveys before returning Internet access.
Whilst this browser hijacker appears ineffectual, computer users should be aware that Hosts file hijackers, ransomware viruses, and fake antivirus programs are often bundled with baking Trojans and other spyware, which collect information used to access certain sites. This information is then collated and sent to a remote machine. Moreover, infiltrated computers can encounter further security-related issues. Trojans, for example, are used to download files from a remote computer and perform other malicious tasks. If you see the "You shall not pass" message when attempting to access popular websites, your PC is infiltrated with a Hosts file-modifying Trojan.
Other Hosts file hijackers used to trick PC users into filling deceptive online surveys include "Your website access has been restricted for downloading pirated software" and "You have been blocked from our website!". The "You shall not pass" Hosts file hijacker is distributed using fake downloads and some Internet users report that their computers are infected with this Trojan when they download Minecraft-related add-ons, account generators, etc. To remove the "You shall not pass" browser hijacker, use the removal guide provided.
