If a program named Diffitic.net has entered your system, you may be facing some of the following symptoms:

  • Modifications in your default browser. Diffitic.net “Virus”could be the most probable reason for some recent changes in your browser’s homepage, default search engine, and new-tab page. These changes are usually imposed without the users’ approval and can take place in practically any browser –  Chrome, Firefox, Internet Explorer, Opera, etc.
  • Redirects to unfamiliar web pages, automatic opening of new tabs and browsing windows. Diffitic.net “Virus” may often be blamed for redirecting people to predetermined sites, and to sponsored web content. The intrusive software usually shows modified search results and sometimes it might even block trusted sites in favor of the sponsored ones.
  • Diffitic.net “Virus” could try to prevent you from uninstalling it from the system. The uninstallation options of Diffitic.net are not easily reachable and initially you may not be able to find a way to remove this pesky browser-redirect from your PC. Even if you remove it, the nagging software may reappear in the system once you restart the PC.
  • Issues with browser performance and system stability. Once Diffitic.net “Virus” starts to operate, you may notice a slowdown in the performance of the affected browser, unresponsiveness, sudden crashes and general instability. You may frequently see system error notifications and overall performance problems.

How dangerous could all these issues be and is there a way to save yourself from the disturbance? You can find out from the next lines.

Is Diffitic.net a virus?

Diffitic.net is a software application/page-redirect that can be categorized as a browser hijacker. This type of software is deemed potentially unwanted but it is still not as harmful as a Trojan horse or as a Ransomware virus, for example. Usually, a browser hijacker gets on your Chrome, Firefox, Internet Explorer or any other browser you might have as a plug-in or as an add-on component that causes certain modifications to your browser’s settings. Normally these changes are related to your default home page, the default search engine, and the new tab page, which could get replaced with some new or unfamiliar ones. With the help of the newly imposed components, Diffitic.net may start to redirect you to some predetermined sites and manipulate your search results in favor of some sponsored web content. The general idea behind this activity is to promote certain websites and their products and increase their traffic. However, there is no guarantee that all the sites that Diffitic.net may redirect you to are legitimate and harmless.

Another typical activity, performed by the programs like Diffitic.net “Virus” is their data-tracking activity. Such browser hijackers may attempt to gather information about the people’s browsing habits and sell it for profit to third parties. It can be said that this is usually done for advertising purposes. Yet, if you want to protect your privacy and get your browsing settings back to normal, you may need to remove the browser hijacker from your system.

How to permanently uninstall Diffitic.net “Virus” from your system?

Fortunately, a piece of programming like Diffitic.net “Virus” can be removed from your system fairly easily and without any damage to your computer. You can generally remove the browser hijacker in two ways – manually or automatically. The automatic removal is the best and the quickest. We generally recommend it to users, which are not quite familiar with the specifics of the browser hijackers and their components and want to uninstall the unwanted program in the fastest possible way. You can use the professional anti-malware tool from this page to do the automatic removal for you or install some other reliable security software of your choice. A detailed manual Removal Guide can also be found at the end of this page, and you are welcome to use it if you are confident enough to find all the Diffitic.net components and manually delete them from your system.

How may Diffitic.net enter your PC and how to prevent it from doing so again?

Unlike the Trojans, Ransomware and other computer viruses, a program like Diffitic.net does not infect you on its own. This software often gets installed by the users themselves and this happens mostly when they follow the Automatic/Quick installation options and do not customize the installation configuration of a given software bundle. Usually, the browser hijackers are distributed as an additional component in different free and attractive program installers, torrents and download managers. That’s why, you should always select Custom/Advanced/Manual settings and carefully disable any “additional”, “recommended”, or “suggested” software that you may not want to install along with the main program.
