virus (Removal Guide) - 2021 update virus Removal Guide

What is virus?

FidoNav – a PUP which redirects to sponsored sites that you would hardly visit yourself pops-out every time you turn on the homepage or decide to use the new tab URL section.

FidoNav is a potentially unwanted program (PUP) which can appear on any web browser after installing freeware[1]. This browser hijacker provides “useful features” such as quick links to popular sites:

  • Facebook;
  • Twitter;
  • Instagram;
  • Youtube;
  • Gmail;
  • Etc.

However, this is due to confusing and convincing users that virus is completely legitimate and very easy to use. Unfortunately, this site should be used with carefulness as the main aim of its developers is to benefit from their users by redirecting them to sponsored content. The biggest issue here is that these sites are hardly monitored and you can be redirected to an infected website.

Name FidoNav
Type Browser hijacker/PUP
“Useful” features Provides fast access to commonly used websites such as Facebook, Youtube, and others
Danger level Medium. PUP modifies browser's settings and starts redirecting its victims to questionable sites
Main risks Being redirected to a malware-infested website
Prevention Download software only from original sites, avoid using third-party installers and deselect all unwanted upcoming downloads which are in the “Custom/Advanced” section
Ways to delete Manual removal; a full system scan with FortectIntego to eliminate virus outcomes

Notice that FidoNav is not as harmful as ransomware-type viruses[2] but it still does changes to your web browser's settings. You can revert the modified settings only by deleting the browser hijacker and all his provided malicious applications. It is advisable to stay away from such programs as they can redirect you to pages which contain false results.

Another problem is that this questionable search engine actively collects user’s search queries and displays sponsored search results based on received data. However, search queries aren’t the only type of information that FidoNav virus collects – it also gathers IP addresses, most visited sites, and other PERSONAL data if you provide it voluntarily. However, the biggest concern here is that the company takes no responsibility for attacks:

FidoNav shall not be liable for any illegal use of your account or passwords caused by hacking or user’s negligence in care.

A well-known search engine can even provide the majority of search results for FidoNav; however, that does not mean that all of them will be entirely trustworthy. The results usually contain a lot of extra results known as ads, so we can call such shady search results “customized.”

There is no point in trusting them, so we suggest deleting the described browser hijacker ASAP. Ads provided as search results are hardly ever endorsed and so they might redirect the victim to dangerous external web pages. We strongly recommend using anti-malware software for FidoNav removal (for instance, FortectIntego). However, the described PUP can be wiped off your computer system manually, too. You just need to use the guidelines provided below the article. experts[3] noticed that the described search site promotes Taboola ads. Although these are harmless, hackers recently managed to compromise the ad network and use these ads to cause redirects to tech support scam pages. Be careful and think before clicking on these catchy-looking articles and ads! It is safer to remove FidoNav from the system instead of putting yourself into danger. hijack brings various inconveniences such as browser crash downs, false URL redirects, and makes surfing the Internet slower.

Keep your computer safe from browser hijackers

There is a very easy method to avoid installation of unwanted programs. It requires just a little attention during software installation.

  • Instead of opting for Standard or Default settings that are typically selected automatically, switch the selection to Custom or Advanced option. This will give you an opportunity to deselect unwanted items that came with your download.
  • Also, try to avoid downloading programs from vague Internet sources, P2P file-sharing networks, and questionable pages. Choose official software developer’s website when looking for a right software download link.

How to prevent from getting browser hijacker

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
