This search engine can stealthily infiltrate PCs and compromise the settings of Google Chrome or any other web browser. Our security experts assign this website to the group of browser hijackers and potentially unwanted programs (PUP).
Such classification is easy to ground: the virus is capable of infiltrating PCs via freeware, changing web browser's settings without authorization, enabling third-party tracking cookies, and initiating multiple advertising campaigns[1].
Since this plug-in-based web domain can lead to more serious problems like malware infiltration of privacy issues, virus removal is a first thing that should be done right after the browser's hijack. People to this day suffer from unexplainable redirects and other issues regarding the site and its suspicious services.[2]
Especially, when this is yet another torrent site that triggers many questions like Thepiratebay. There are many issues related to these services and sites promoting and providing content like pirated software and game cracks. There are some ransomware families that distribute their virus variants like Copa or Kolz via torrent files.

If accessed, this domain may not seem suspicious. It's a website that offers Peer-to-Peer file-sharing functions and is called a “torrent” search among netizens. Its start page looks modern and appealing, full of content, though minimalistic. 1337x.to virus contains a search engine that fosters to “search for torrents,” as well as a bunch of quick access links to games, music, apps, anime, documentaries, and even links to adult content.
Although it may seem convenient at first, do not trust this domain as it may be involved in various shady activities, such as:
- Distribution of other PUPs or even malware;
- Collection of personally non-identifiable information;
- Browser's redirects to affiliated websites;
- Presentation of individualized ads that contain irrelevant content;
Family members of the article's culprit, including similar domains, fall for the category of browser hijackers. Even though to can be easily accessed by typing its URL into the address bar, people in cybersecurity forums keep reporting that they found their web browser's start page and search engine replaced by hijacker without their permission. Stealthy installation via freeware is the reason why this dubious torrent website can appear on the system.
Once a freeware bundle is installed on the system, additional programs, such as plug-ins and add ons, are extracted and injected into the web browser's settings by default. Consequently, regular Google's start page and a search engine are modified, as well as other preferential web browser settings.
Such activity is annoying, but that's not the worst part. People reported that the hijacker generates intrusive pop-up ads regularly. These activities can lead to other issues and even system damage, so you must get rid of the virus and run a tool like FortectIntego, so the damage gets repaired. 
Sometimes, these ads force the web browser to freeze. Udenvirus.dk[3] team has tested their ads and revealed that most of them offer to visit casinos, pornographic websites, or affiliated torrent sites. Be very careful because visiting such websites can lead you to malware installation or virus infection.
Also, this PUP may cause redirects to third-party websites to increase their visitors' rate and generate financial profit. Therefore, the hijacker may be the reason why you receive altered search results, many hyperlinks within random texts, shady-looking advertisements, and other misleading content.
Section +18 is yet another concerning factor. The quick link bar provided on the start page of the 1337x.to down below the search bar contains a link to adult content. Clicking the link does not require age verification, and the user gets exposed to the download of porno movies[4]. It's not a secret that visiting adult content websites is the perfect medium for getting a PC's system infected with malware and viruses.
Last but not least issue to discuss is related to privacy violations. Most PUPs employ tracking cookies to collect as much information about peoples' browsing activities as possible. The virus may also try to accumulate information like:
- URLs visited
- Click
- IP address
- Approximate geolocation
Nevertheless, the website allows people to register by entering the user name, password, email address, country, and other sensitive information. Even though you are an active torrent user and opt for such a service, we do not recommend trusting this hijacker as it may be related to third parties and try to misuse information provided for various purposes.
Therefore, if you noticed your web browser's changes initiated by this hijacker, do not wait for too long and perform removal with SpyHunterCombo Cleaner, MalwarebytesMalwarebytes, or another antivirus tool. You need help from such software, so the process is quick.
Pre-bundled programs spread without additional permissions
The first sign proving that a browser hijacker has infected the system is the replacement of a web browser's start page and search engine. Other side effects, such as browser's slowdowns, crashes, intrusive advertising, or redirects manifest later during web browsing sessions. Commercial content may also chase you while browsing the web; therefore, you may get exposed to unwanted websites or accidentally download malware to the system.
If you wonder how such and similar infections manage to get inside the system, keep in mind that free programs downloaded from untrusted (or sometimes trusted) download websites are used for the distribution of add-ons, plug-ins, and similar malware.
Even though experts are trying to raise peoples' consciousness about software bundling, there still a strong tendency among internet users to download freeware without checking their reputation and reliability. Besides, people fail to single out the Advanced installation option, which enables potential victims to monitor and opt out of additional components.
Nevertheless, not only software bundles may inject PUPs into the system. Unwanted programs can also land on the system after visiting illegal websites and having contact with advertising content. One of the trickiest ways to spread PUPs is fake system scanners, which emerge on the web browser's screen in the form of a pop-up saying that a virus has attacked the system. After running a scan with a supposed-to-be antivirus, the user is informed about the infection and offered a free antivirus tool. This way, people may get tricked into downloading PUPs, as well as spyware, Trojan, or other virus.
