Remove NavSmart Smart Engine redirect (Removal Guide)

NavSmart Smart Engine is a browser hijacker that is bundled with other free software that you download off of the Internet. When installed this browser hijacker it will set the homepage and search engine for your web browser to http://navsmart.info/.

This itself is not considered malicious as there are many legitimate programs that change these settings as well. What is considered malicious, though, is that it will also append the argument http://navsmart.info/ to random Windows shortcuts on your desktop and your Windows Start Menu.

NavSmart Smart Engine virus

NavSmart Smart Engine homepage got on your computer after you have installed a freeware software that had bundled into their installation this browser hijacker. Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed this malicious program without your knowledge.

For example, when you install NowUSeeIt Player, you will also agree to change your browser homepage and default search engine to NavSmart Smart Engine.
However when you uninstall NowUSeeIt Player from your computer, your web browser’s default settings will not be restored. This means that you’ll have to remove NavSmart Smart Engine homepage from your favorite web browser manually.

NavSmart Smart Engine uses a variety of Registry entries to hijack your browsers even after you clean your shortcuts or change your homepage settings. For example, this browser hijacker adds the HKLM\SOFTWARE\Wow6432Node\Policies\Google\Chrome\HomepageLocation and HKLM\SOFTWARE\Wow6432Node\Policies\Google\Chrome\RestoreOnStartupURLs\1 registry policies that will automatically open Chrome to the http://navsmart.info/ site even if your shortcuts are cleaned and you have your homepage set to another location.

You should always pay attention when installing software because often, a software installer includes optional installs, such as this NavSmart Smart Engine browser hijacker. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.
