What is Under-Cover.info virus?

Under-Cover.info is a browser hijacker that modifies web browser settings in order to show users fake search results

Under-Cover.infoUnder-Cover.info is a potentially unwanted program that is usually injected after the installation of free software

Under-Cover.info is a browser-hijacking application developed by Kinner Lake Limited – a Gibraltar-based company. The unwanted programs usually enter machines without users noticing, as software bundles typically try to hide optional installs under Advanced settings, and most people simply skip this step by choosing the Recommended mode. Once inside the machine, Under-Cover.info virus starts performing a variety of changes, including the ones that modify users' homepage and a new tab, along with the search engine. From that point, users are forced to browse via the hijacked engine,[1] which typically shows them fake search results that include a colossal amount of sponsored links, deal with redirects to questionable websites, and suffer from the slow operation of the browser.

While browser hijackers are not considered to be severe computer infections, their presence might compromise computer security and users' online safety. In this article, we will explain peculiarities of this type of threat, and will also describe how to remove Under-Cover.info from Google Chrome, Mozilla Firefox, Safari, Opera, or another browser.

The primary goal of Under Cover Search developers is to generate traffic to sponsored websites, which would consequently increase the profits for both parties. For that, PUP authors need to make sure that Under-Cover.info hijacker reaches as many users as possible – hence the shady distribution technique.

Once the changes to the installed browsers are made, Under-Cover.info starts its shady activities by displaying sponsored content, placing a layer of ads on most sites, exposing to altered search results, and also tracking users' web browsing activities. This is done with the help of tracking technologies, such as Beacons[2] or Cookies. This information-gathering allows Under-Cover.info developers to gather the following information:[3]

  • technical information transmitted by your device such as type of operating system, device type, default browser;
  • your aggregated use of the Software, basically we know if you installed the software;
  • usage statistics;
  • language and the time stamp;
  • approximate geographical location.

This data is collected in order to generate personalized ads, but these are always coming from the affiliates. Therefore, Under-Cover.info hijack can manipulate what sites users visit, influence their interests and make them buy products or services that they otherwise would not.

Therefore, while the browser hijacking changes might seem relatively minor, it might result in the installation of potentially dangerous apps, exposure to online scams, and even malware infection. Thus, if you noticed that your homepage has changed, check your system with security software or perform manual Under-Cover.info removal as explained below. After you kill the PUP, make sure you use FortectIntego or similar repair software to bring your device to a pristine condition.

Make use of Advanced installation settings to avoid PUPs

If you do not want to let potentially unwanted programs hijack your computer, you should pay more attention to the software installation process. Contrary to many people’s beliefs, Default or Recommended installation settings are not the ones that should be trusted during the procedure.

In fact, Custom or Advanced settings will allow you to determine which applications are secretly offered to you. Therefore, opt for these settings because they enable you to reject unwanted items added to the desired software. Be aware that most of the free apps will include some sort of “offer” or “deal,” and it might be hidden in various ways, including grayed out buttons, pre-ticked boxes, misleading placement of the toggle, etc.

There are two ways to terminate Under-Cover.info from your computer

As we already mentioned, the presence of a browser hijacker will not bring you any benefit but instead will manipulate the search results and expose you to potentially dangerous content. For that reason, it is best to take care of Under-Cover.info removal before you compromise your computer safety.

You can remove Under-Cover.info virus manually or automatically. The latter option is best for those who are less tech-savvy, however. It will allow you to terminate the unwanted application in just a few minutes. Simply download and install a security program that focuses on potentially unwanted program removal and then perform a full system scan. Alternatively, you can also use our instructions below to delete the PUP manually.

How to prevent from getting browser hijacker

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
