“Guide” is the name of a rogue browser extension that could compromise your Chrome browser. However, other browsers could be affected as well. Being ad-supported, the Guide extension would generate ads and cause redirects to suspicious pages. If you notice that your default search page is changed, then the extension is also a browser hijacker.
Because they covertly tamper with browser settings, hijackers are capable of changing your homepage, new tab page and the default search engine to a website of its preference. Just like any other ad-supported program, the sole purpose of these apps is quick monetization by launching pay-per-click campaigns.
Other examples of suspicious browser extensions include DimScreen and SkipTheAdz. Usually, suspicious extensions are advertised as useful utilities on web stores (such as Chrome Web Store), but when you install them, you discover they fail to provide any useful functionality. You could easily spot that an extension is suspicious if it lacks any real user comments and a sufficient rating.
Below you will find popular ways that suspicious developers employ to distribute browser redirects, hijackers, adware and PUPs. One of the most common ways is using bundled software installations, a.k.a. software bundling and bundled installers, which is not an illegal practice but could be used to generate profit on a pay-per-install basis. Furthermore, there is no telling where such a redirect could take you, as it may lead you to a scam website that could try to make you download a rogue software product.
Also note that the extension may be available for download on third-party stores. Sometimes, suspicious extension sneak into legitimate, official stores, such as Chrome Web Store. For example, last year, Google removed 106 malware extensions from its Web Store following an audit of irregular code.
The appearance of the Guide Extension extension may be a result of a bundled installer. Such bundled installers come from download sites that host packaged archives laced with adware, browser plugins, potentially unwanted applications (PUAs), and even malware. You may have downloaded such an installer in an attempt to download a legitimate application.
As we already mentioned, software bundling is not illegal but it often causes unwanted, additional downloads, even of legitimate products. To avoid it from happening, you should be more careful during the installation steps of freeware applications.
These are popular examples of fake tech-support scams that are known to cause browser redirects and unwanted downloaded on affected computers.
Also, be aware that if you interact with any of the content generated by Guide Extension, you may end up being flooded with even more unwanted apps. That is why we encourage you to make sure your computer system is safe against any related online threats.
Is Guide Extension a Virus?
Long story short, suspicious browser extensions and adware are not considered computer viruses. However, they are known to take users to suspicious pages. If you interact with any of the content it provides, like clicking downloading the provided extension, you can unknowingly install a potentially unwanted app or browser hijacker. If your homepage and new tab page are changed without your consent, you may have a browser hijacker “attached” to your browser.
