Guj5.xyz redirect removal instructions
What is guj5.xyz?
Guj5.xyz is one of the fake search engines that are promoted through a potentially unwanted application (PUA), a browser hijacker called CERX. This PUA is related to another app of this type called QIP. As a rule, browser hijackers promote fake search engines by changing certain browser's settings. Also, most of them are designed to collect various data related to user's browsing activities. It is worth mentioning that guj5.xyz may be promoted through other browser hijackers (like Smash App +) as well.
Typically, browser hijackers change settings such as address of a homepage, default search engine and new tab. They make sure that users would visit an address of a fake search engine when they open a hijacked browser, new tab, or enter search queries into URL bar. Research shows that this particular app (CERX) does not always change the aforementioned settings. Even if it does not change them, it still detects when users enter search queries and redirect them to guj5.xyz. It is worth mentioning that guj5.xyz gets opened through qxsearch.com, another shady page. Either way, the only way to stop a browser from opening guj5.xyz (and qxsearch.com) is to uninstall CERX or any other app that is designed to promote this fake search engine. Furthermore, browser hijackers usually are designed to collect information related to user's browsing activities as well. Typically, they collect details like IP addresses, geolocations, entered search queries, addresses of visited websites, and other browsing-related data. Their developers tend to misuse gathered data to generate revenue, and/or they sell it to third parties (potentially cyber criminals) who use it for the same purpose. It is worth mentioning that browser hijackers can be designed to record not only browsing data but various personal information as well. People who have their browsers hijacked by apps of this type are being put at risk of problems related to browsing safety, privacy and so on. It is possible that gathered data may be misused to steal their identities as well.

To eliminate guj5.xyz browser hijacker our malware researchers recommend scanning your computer with Spyhunter.
Other fake search engines that are promoted through CERX are bhj1.xyz, mkob.xyz and qikc.xyz. It is worth mentioning that browser hijackers often are advertised as useful, legitimate. They supposed to deliver various features or other value, however, very often they are completely useless. Quite often they are designed only to help their developers to generate revenue and put users at risk of various problems. Therefore, we recommend to uninstall CERX, Smash App+ or any other browser hijacker that is (if is) installed on a browser and/or operating system.
How did guj5.xyz install on my computer?
Very often developers proliferate PUAs by using a deceptive marketing method called "bundling". They use this method to trick people into downloading and/or installing unwanted apps together with some other programs. They include PUAs in their download and/or installation setups and put information about it in their "Custom", "Advanced" and other similar settings. People who download and/or install programs without checking those settings often download and/install more than just a desired program. Sometimes unwanted downloads and/or installations can be caused by clicking deceptive ads that are desingned to run certain scripts.
How to avoid installation of potentially unwanted applications?
All software should be downloaded from official websites (and via direct links). Peer-to-Peer networks (torrent clients, eMule, and so on), unofficial websites, third party downloaders, isntallers, and other similar download and installation tools should not be used. Quite often they are monetized by promoting various unwanted applications. Also, we recommend to always check settings (like "Advanced", Custom" and so on) of any download and/or installation setup and dismiss offers to download and/or install unwanted software. Intrusive advertisements that are displayed on unofficial (unreliable) web pages should not be clicked. It is because they often open potentially malicious websites or cause downloads, installations of unwanted apps. And finally, if there are any unwanted, suspicious apps (extensions, add-ons, plug-ins) installed on a browser or programs of this kind on the operating system, then they should be uninstalled as soon as possbile. If your computer is already infected with browser hijackers, we recommend running a scan with Spyhunter for Windows to automatically eliminate it.
