“Guide” Extension is a browser hijacker capable of “stealing” the settings of your Chrome, Firefox, or Edge browser, and turning the program into a site-promoting platform. Once installed, Guide Extension will begin spamming the browser with ads, pop-ups, and box messages, and make unwanted changes to it.
The browser hijacker category encapsulates a wide variety of apps, browser extensions, smaller software components, and even websites, all of which have one main common trait – they try to gain some amount of control in the user’s browser and then use that browser to promote certain sites, services, products, etc. Many hijackers are also known for collecting data from the targeted browser and then use it for optimizing their ads to for selling it to third-parties for extra profit.
It is typically very easy to spot a hijacker – symptoms like replaced browser search engine or starting page without permission or automatic page-redirects that reroute the browser to unknown websites are difficult not to notice. Additionally, the PC may become slower due to the constant generation of ads and some other processes that the hijacker may run in the background. It’s even possible that unwanted browser add-ons get installed without the user’s informed approval.
How high is the danger?
All those hijacker symptoms could seem quite unnerving and lead you to think that the system has been attacked by some highly-dangerous Trojan Horse, that could soon infect you with other threats, such as Ransomware, Spyware, or Rootkits. The good news is that Guide Extension and most other browser hijackers are mostly harmless, in the sens that they don’t have the ability to cause damage to anything on your computer.
That said, they are also not apps to be ignored and left in the system or long periods of time. Even if Guide Extension isn’t designed to harm your files and system, it is still an app that does something that it shouldn’t, which could often mean that your computer is becoming less safe and secure. Take the ads for example – you have no real way of stopping them other than deleting the hijacker, and you could never know if the next one won’t send you to a phishing or malware-distributing page, should you accidentally click on it. Granted, the risk of landing a Ransomware or a Trojan in this way is still relatively low, it’s still an unnecessary risk, especially since you don’t get anything in return. It is exceedingly rare for a browser hijacker to actually have any useful and helpful qualities, so there’s really no reason for that app to be kept on the computer.
This is where the problem with the removal of Guide Extension comes into play – apps like “Guide” or “Viewer” extension can be quite tricky to fully get rid of. Fortunately, if you make sure to follow the guide we’ve included down below on this page, you should be able to manually eliminate the undesirable software. Furthermore, even if there’s something left behind from the hijacker after you are done with the guide, the professional removal tool linked on this page can help you fully clean your system, so that there’s no traced of Guide Extension left in it.
Some threats reinstall themselves if you don't delete their core files. We recommend downloading SpyHunter to remove harmful programs for you. This may save you hours and ensure you don't harm your system by deleting the wrong files.
