This program is a browser hijacker – normally a harmless type of software, which cannot cause your system serious damage. However, Go.oclasrv.com “Malware” may eventually be seen as a source of irritating browser modifications, which may affect the way your Chrome, Firefox or Internet Explorer operate.

Just continue reading and you will also learn how to protect your PC from browser hijackers in the future.

The real nature of the “browser hijackers”:

Many users often think that programs like Go.oclasrv.com are some sort of viruses. Browser hijackers tend to aggressively interrupt the normal web browsing with their annoying ads, redirects, new homepage and search engine settings, and may even keep track of the users’ browsing activity. However, these activities are not enough to classify these programs as malicious. The real purpose of the browser hijackers is to simply serve as adverting tools for the online marketers. They are not developed to cause harm, and this is what distinguishes them from threats like Ransomware, Trojans, Spyware and other nasty online infections. If you have Go.oclasrv.com on your system, your files and your OS will most probably not get affected, but this will not be the case if you get attacked by Ransomware, for example. Still, you may get disturbed by the aggressive advertising methods that this software may employ. For instance, you may not want to face a wall of ads every time you open your browser. Or you may not find it safe to get redirected to various unfamiliar sites, which could be a good reason for you to wish to uninstall the hijacker. In fact, we will encourage you to do that in case that your normal browsing is seriously disturbed.

To remove Go.oclasrv.com “Malware” once it has been installed, however, the settings of the setup will not work. You will need to detect the hijacker-related files and uninstall them either with the help of some detailed removal instructions or by scanning your PC with a reputed tool. We can offer you the professional Go.oclasrv.com removal tool as an automatic solution, but if you are looking for manual instructions, the Removal guide below is at your disposal.

Where can browser hijackers usually be found and how to prevent them?

Browser hijackers are commonly encountered all over the Internet. Since they are not malicious, these programs are legally distributed via email messages, free download links, various web pages, and many more sources. You cannot get infected with them unless you willingly download and install them on your system. However, you may not always be clearly notified about their installation. Below we have listed some of the usual places where you can find programs like Go.oclasrv.com, so you can gain an idea:

  • Freeware and shareware sites – Browser hijackers and various other ad-generating programs can be found on sites that offer some free software. Torrent platforms and pages that provide free download setups could also be full of such programs.
  • Spam messages and email attachments – Many online ads, which may pop up in your browser, may contain a hijacker like Go.oclasrv.com. Most of the time, you may download such software by clicking on a spam message that promises you a better browsing experience and a free browsing tool.
  • Software bundles – The most common hijacker source is the so-called “software bundle”. This is a set of programs, (they could be apps, games, optimization tools, audio/ video tools, etc.) which you can download, install and use free of charge. Oftentimes such bundles contain ad-generating programs such as Go.oclasrv.com and promote them as “suggested software”. Users usually make these programs part of their system by installing the whole bundle as it is without paying much attention to the suggested software settings. Fortunately, this can easily be customized and with just a few clicks anyone can prevent a potentially unwanted browser hijacker from getting installed on their PC. How to perform a hijacker-free installation, you may ask? Well, it is important to apply one easy customization tip every time you download and install new software. Basically, you need to select the Advanced/ Custom/ Manual installation option and carefully unmark every pre-selected component that you think you may not need. This can save you from tons of bloatware and potentially unwanted programs, which may get installed by default if you don’t remove them manually.
