Web Surf Shield virus removal instructions
The 'Web Surf Shield virus' is a term used to describe a Windows Hosts file-modifying Trojan. This security infection was created by cyber criminals to trick unsuspecting PC users into completing deceptive online surveys, and thus, generate affiliate revenue from them. Commonly, this Hosts file hijacker infiltrates systems through fake downloads (such as Facebook password-hacking tools, router password-hacking tools, etc), P2P networks, and infected email messages. After successful infiltration, the Web Surf Shield Trojan modifies the Host file of an infected operating system by adding various entries. This modification assigns Internet browser (Internet Explorer, Google Chrome, and Mozilla Firefox) redirects to the Web Surf Shield page, which states "Access to this page has been temporally blocked. Please take time to download our web shield update below. You can continue accessing the site after installing update. Thank you".
Redirects to this page occur when attempting to access various popular websites such as Google, Facebook, Bing, etc. Do not be fooled by this message. Do not download Web Surf Shield or complete any online surveys to supposedly 'unlock' this download. If you observe such a message on your computer, you are dealing with a Hosts file hijacker. The correct way to deal with this security infection is to eliminate it from your computer.

Note that completing online surveys is not recommended since they often present online forms requesting personal or banking information. Divulging this information can lead to privacy issues or identity thefts. Online surveys can also result in inadvertent installation of various potentially unwanted applications, malware, or subscriptions to expensive and useless mobile services. Cyber criminals responsible for creating the Web Surf Shield Trojan make money from each person to complete these deceptive online surveys. Note also that previous variants of this Hosts file hijacker were named "You have been blocked from our website!" and You shall not pass virus.

Internet browser redirects to malicious websites (which attempt to force computer users into filling online surveys), are caused by a Trojan, which modifies the operating system Hosts file. To remove this Trojan, download recommended malware removal software and run a full system scan.
Following elimination of the Web Surf Shield Trojan, check your operating system Hosts file. Information stored in this file is responsible for resolving canonical names of websites - if the information in this file is changed by a malicious program, you may encounter redirect problems whilst surfing the Internet.
The Hosts file is used to resolve canonical names of websites to IP addresses. When it is changed, the user may be redirected to malicious sites, despite seeing legitimate URLs in address bar. It is difficult to determine sites are genuine when the Hosts file is modified. To fix this, please download the Microsoft Fix It tool, that restores your Hosts file to the Windows default. Run this tool when downloaded and follow the on-screen instructions. Download link below:
