The more you surf the internet, the more you realize just how important it is that your browser is as fast and as efficiently as possible. This is why users generally find it really unpleasant and frustrating when their IE, Firefox or Chrome browser gets taken out of their control and gets needlessly modified by some sketchy program that has installed a new search engine and replaced the previous homepage or that tends to cause nagging redirects to other websites. Truth be told, there are actually many software applications that are known to do exactly that – they get inside your browser and start to mess with its settings, which is usually done for marketing purposes. The term used to refer to this type of software is Browser Hijackers. Today, we will be focusing on a program called Youndoo “Virus”, which is one of the newest programs that falls under this software category. You are about to learn some valuable info regarding Youndoo “Virus” and Hijackers in general that will greatly help you avoid such programs in the future, as well as learn how to remove them from your PC in case that one such application such as Youndoo “Virus” has already gotten in your system.

Why Hijackers are not viruses

There’s an ongoing debate regarding whether or not programs such as Youndoo “Virus” are actual malware. Well, undoubtedly, there are a number of similarities between a typical Hijacker and a computer virus. However, this is not to say that Youndoo “Virus” is the same as a malicious Trojan horse or malign Ransomware in terms of potential harm that it can cause or what its goal actually is.

  • The first big difference between a Browser Hijacker and a real PC virus is the purpose of the program in question. Hijackers are primarily used for generating income through online advertising which, on its own, is not inherently harmful for the user. Viruses, on the other hand, are used for the purposes of online crime and the ways through which they are employed threaten both the user’s online security and the safety of their PC system and personal data.
  • Secondly, bear in mind that a lot of Hijackers are, in fact, legal. Even though programs that fall under this category are considered to be unwanted, this does not mean that they are forbidden by the law. The same, however, cannot be said about viruses – those are always illegal and illegally used.
  • Thirdly, when talking about symptoms, most types of malware are programmed in such a way so as to minimize the symptoms that might give away their presence on the computer. With Hijackers, it is the exact opposite. Programs like Youndoo “Virus” are supposed to be as conspicuous and as noticeable as possible in order to be more effective as online marketing tools.

Be on your guard!

A Hijacker might not try to directly cause any real harm to anything on your machine, but some of the things it can potentially do can leave your PC open to more serious hazards.

  • Browser Hijackers have the potential to fill one’s browser program with obnoxious and obstructive online ads in addition to the unpleasant browser modifications. Some of them might actually be redirect links to shady and potentially harmful sites, which is why you should keep away from the ads.
  • An infamous trait of some Hijackers is their ability to obtain data from the browser’s recent history. The information is used to make the generated ads appealing to the individual user, thus making it more likely that the customer would click on them.
  • It is not uncommon that applications such as Youndoo “Virus” would attempt to introduce changes to the computer’s Registry. Such changes can affect the general online security of the system and leave it vulnerable to harmful viruses like the ones we mentioned in the previous paragraph (Trojan horses, Ransomware, etc.).

Our tips for PC protection

Right below this final paragraph, you can find a removal guide that will help you uninstall and fully eliminate the unpleasant Youndoo “Virus” from your PC. However, there’s one more thing to learn before you get there and it is what you must do from now on in order to ensure that no more nagging and unwanted Hijackers get installed onto your computer system.

  • A lot of browsers have a setting that allows them to automatically download certain files. While this can be a useful feature, if you want to get that extra PC protection, make sure to disable the setting.
  • A frequently employed technique for distributing Youndoo “Virus” is the use of online spam. This is why you must always take a few moments to see if any of your newly received e-mails look like spam and if they do, be sure to delete them without opening them.
  • A very important factor when it comes to fending off Hijackers is how careful you are with the sites you visit and choose to download from. Our advice for you is to stick to web addresses that you know are reliable and trustworthy while at the same time avoiding any shady and potentially harmful ones.
  • File bundles are also commonly used for spreading Hijackers. Therefore, always check the setup wizards of programs you are going to install for any added applications and always opt for the advanced installation settings. If you see that there are any added installs, look them up so as to determine whether they are safe. If anything seems fishy about the bundled applications, you’d better leave them out of the installation process.
