SafeSearch is an ad-supported, cross web browser plugin for Internet Explorer and Firefox/Chrome. The browser extension will modify the default or custom settings of the browser including the home page, search settings, and in some cases will modify Internet Explorer’s load time threshold, place a lock file within Firefox to prevent changing settings as well as disable the browser’s Content Security Policy in order to allow for cross-site scripting of the plugin. For these reasons, it has been classified as a browser hijacker.

From the publisher: SafeSearch created by AVSoftware is the unique search engine that filters malicious sites or sites with bad reputations. Every website is weighted on several critical factors – vendor reliability, child safety, privacy issues, user opinions, and ratings.

SafeSearch has been found to be bundled with 3rd party software and malware and therefore is not recommended to keep on your computer.

About Browser Hijackers

Browser hijacking is amongst the internet’s constant problems that target browsers. It’s a kind of malware program that directs web browser requests to some other malicious sites. They’re created to disrupt browser functions for several purposes. Typically, the idea is to force users to visit certain websites that are trying to improve their visitor traffic and produce higher ad revenue. Even though it might seem naive, all browser hijackers are damaging and therefore always regarded as security risks. Furthermore, hijackers can make the entire infected system vulnerable – other dangerous malware and viruses will take hold of these opportunities to intrude into your PC effortlessly. Browser hijacking symptoms There are several signs of web browser hijacking: home-page is changed; you see new unwanted bookmarks or favorites added, usually directed to advertisement-filled or pornography websites; the main web browser settings are altered and undesirable or insecure sites are added to the trusted websites list; you notice many toolbars on your internet browser; unstoppable flurries of pop-up advertisements show up on your PC screen; web pages load very slowly and at times incomplete; you cannot visit specific sites like homepages of security software.

So how does a PC get infected with a browser hijacker?

Browser hijackers infect computers in numerous ways, including via a drive-by download, a file-share, or an infected e-mail. They could be included with toolbars, add-ons, BHO, plugins, or browser extensions. Also, some shareware and freeware can put the hijacker within your computer through “bundling”. An example of some notorious browser hijacker includes Conduit, Anyprotect, Babylon, SweetPage, DefaultTab, Delta Search, and RocketTab, but the names are continually changing.

Browser Hijacker Malware – Removal

Certain hijackers could be removed simply by uninstalling the related freeware or add-ons through the Add or Remove Programs in the Microsoft Windows control panel. However, the majority of hijacking codes are certainly not simple to remove manually, as they go much deeper into the operating system. Moreover, manual removal expects you to perform several time-consuming and intricate procedures that are tough to conduct for novice computer users.

What you can do if Virus Stops You From Downloading Anything?

Malware can cause all kinds of damage once they invade your PC, from stealing your personal information to erasing data files on your PC. Certain malware variants alter internet browser settings by adding a proxy server or modify the computer’s DNS settings.
