I-Search.Us.com Redirect

What is i-search.us.com?

I-search.us.com is described as a legitimate website, which can be used as a homepage and default search engine. This website is distributed using a deceptive free software marketing method called 'bundling' - stealth installation of third-party apps together with other software.

After successful infiltration on Internet Explorer, Google Chrome, and Mozilla Firefox, this browser hijacker assigns the default search engine, new tab URL, and homepage settings to i-search.us.com.

Additionally, it installs together with several applications called 'helper objects', which are developed to prevent users from reverting these changes. Users commonly install i-search.us.com together with software downloaded from freeware download websites.

Popular freeware download websites (for example, download.com, soft32.com, and softonic.com) monetize their traffic and free services by employing small 'download programs' (also called 'installers', 'downloaded managers', 'download clients', etc.) These applications offer installation of third-party apps (often categorized as adware or malware) together with the chosen free software.

Following computer infiltration, the user observes intrusive online advertisements that are likely to cause further computer infections.

Moreover, these rogue applications collect information that may be personally identifiable. Thus, the presence of this third-party software on your system may lead to serious privacy issues. You are strongly advised against the use of i-search.us.com as your default search engine, since the displayed search results can cause further infections.

I-search.us.com is similar to other regular browser hijackers. For example: searchult, dregol, and palikan. These browser hijackers have identical behavior to i-search.us.com and provide no real value to the user - they are developed to generate revenue by the display of ads, redirecting users to various dubious websites, and sharing collected data with third parties.

To avoid these infections, closely inspect each step when downloading free software and never accept offers to install additional apps. Furthermore, downloaded software should be installed using the 'Custom' or 'Advanced' installation options, rather than 'Quick' or 'Typical' - this will reveal any third-party apps included for installation and allow you to opt-out.

If your browser continually redirects you to the i-search.us.com website without your consent, the following removal guide will help you to eliminate this problem from your system.
