Technically, this is a potentially unwanted activity which many users may report as irritating and nagging. Luckily, it is not malicious for the most part. To our and your relief, the changes that “Virus” might impose are closely related to popular online advertising methods such as sponsored ads positioning or Pay-Per-Click campaigns which usually have no criminal intentions. For this reason, neither this application nor the browser hijackers’ software group in general are considered as viruses. Such applications are created solely to advertise and not to harm your PC, encrypt your data or steal your information. Therefore, you cannot compare them to real malware such as Ransomware, Trojans or Spyware.

Still, despite the fact that the browser hijackers do not try to gain anything from you via illegal or harmful activities, you may not want to keep them on your PC. The reasons for that may be several. For instance, due to its page redirecting service, an application like “Virus” may land you on web locations which you never intended to visit. Perhaps non-intentionally, the hijacker may also expose you to sketchy or risky content, which might be infected with a real malware like a Trojan horse or a Ransomware. Furthermore, in its attempts to display sponsored ads on your screen, the application may cause your browser to crash or become unresponsive to your searches. All this could severely disturb any attempt of yours to browse the web normally which is why you might want to uninstall “Virus” as soon as possible.

Distribution and safe removal of “Virus”

The browser hijackers are often bundled inside other applications’ installers (mostly free software setups, free games packages, new applications installers, etc.). They may also be found in different torrent platforms, freeware sites or free download links, which might get distributed via spam, ads, email attachments or social shares. Opposite to viruses, however, these pieces of software cannot infect you or sneak inside the PC in a stealthy way. To become part of your system, the browser hijackers actually require your permission to get installed. The programmers who create them often promote them as “recommended” or “additional” components to many other popular pieces of software. Unfortunately, most of the users do not pay close attention to what additional software they agree to install on their computer along with the given application they desire. That’s why they skip reading the EULA and typically proceed with the Automatic/Quick installation setup without checking for bundled content and this is how they end up with pieces of software like, nagging Adware programs or similar ad-generating apps. Those, who carefully read all the fine print, click on the Advanced/Manual/Custom setup options and check for pre-selected additional components, however, can easily leave out any potentially unwanted software and save themselves from the need to uninstall it later. The people who have not carefully completed the customization of the setup and end up with a browser hijacker, on the other hand, may need a professional removal tool (such as the one on this page) or a detailed Removal Guide like the one available here to remove the undesired application.
