This page aims to help you answer the question What is Rfihub?. These Rfihub “Malware” removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

In the following text we will be discussing one very irritating program – Rfihub “Malware”,  in detail. The presence of this browser hijacker inside your system could result in the entire modification of all your browsers’ appearances and ways of acting. Among the potential effects of this program may be some unwanted redirecting to various websites; some continuous and sometimes slightly intensive broadcasting of pop-up and other ads whatever browser you open – Chrome, Firefox, or Explorer. One more rather annoying consequence of most browser hijackers is the unauthorized substitution of your default browser app homepage and/or search engine. More information about this kind of software – browser hijackers, is available in the paragraphs below. When we talk about hijackers, it is essential to point out that these programs may just infect your browser apps. Also, they have really nothing to do with viruses. Usually, their typical behavior is simply marketing-driven. Logically, this could explain all the alterations they may make, as their developers have signed contracts, which promise them generous payment in exchange for the effective promotion of particular websites; search engines or homepages; as well as various products or services. Such software is legitimate and might simply be characterized as the ad-producing type like Adware.

What is Rfihub?

The normal malware versions like the ones based on Trojans or Ransomware can perform something very harmful once they have infected your PC. For instance, the Ransomware viruses may encrypt data; and the Trojans could destroy files or format all your disks and drives. Fortunately, nothing like that could be expected from Rfihub. What it may do at times is review your last search requests and adjust the production of the many advertisements to your supposed interests and search requests. Such a trait may come across as quite intrusive. Despite that, such a review of your browsing history may prove to be helpful to you. If this hijacker could generate ads, based on your interests, you may receive the best offers automatically. Still, most users see such activities as far too irritating and that’s why hijackers are often considered potentially unwanted by many experts.

How you are most likely to end up infected by hijackers like Rfihub

Although, ad-generating programs could be found almost everywhere on the Internet, you are most likely to experience such an infection if you download and install any free program bundle from the web. Let’s explain what a bundle represents – briefly speaking, it is just many various programs mixed and spread together as a package. The content of any bundle may include games, apps, Adware-like products, browser hijackers and other kinds of software. Simply make sure that you bear in mind that getting such a free bundle is not what really causes an infection. What does, however, is improperly installing such a software mixture.

Which are the “good” installation options? Which ones are considered “bad” choices?

As soon as the installation wizard pops up, you will be given the available installation features. From the list of the ones that you can see, search for the Advanced/Custom or Customized one. Follow only its instructions in order to complete the process. Remember that only this option will enable you to choose what exactly to install and what to disregard from a given bundle. Just try to avoid all other installation features, such as the Brief; Typical; Default; Automatic; Quick ones. They are not good in case you need to avoid ad-broadcasting programs.

Some more tips on prevention

Besides the aforementioned way of incorporating any program that you want to try, using these steps may greatly lower the risks of catching Rfihub:

  • Stay away from all the other potential sources of hijackers, including torrents; shareware and spam. Also avoid add-ons and enabling browser extensions.
  • Make sure that your OS is functioning properly and is frequently updated.
  • You DO need a great anti-virus program. In case you don’t have one, please, purchase one. They are extremely useful tools and can warn you about potential threats.
  • Take a look at your Firewall. See whether it is functional. Make sure that you update it on a regular basis and keep it on.
  • Just be wise about your browsing activities. Mind the addresses you go to.
