What is Big Linker?

Big Linker – a browser hijacker that will inject ads into search results

Big Linker browser hijackerBig Linker browser hijacker modifies browser settings to reroute all search traffic through a site of its choice and inject ads in the search results

Big Linker is deemed as a potentially unwanted program[1] because of the way it operates and is spread. This piece of software will modify your infected browser settings by changing the new tab, default search engine, and homepage to keysearchs.com. Each time a search query is entered, a new tab will open with altered results from Bing, Yahoo, Google, or other legitimate sources, depending on your geolocation.

By causing redirects, this browser hijacker is able to record your browsing history. And what's worse, the redirects allow it to alter search results and display ads in them. And here's where things could get complicated as deceptive Big Linker ads might result in various mishaps.

It doesn't matter if you installed this PUP willingly or it got on your device unknowingly. The important thing is to remove it. This article explains the subtle browser hijacker delivery techniques, their functions, symptoms, risks, and of course, removal options.

System Health Use the powerful ReimageIntego system repair tool to delete any tracking cookies, clean up junk files, and most importantly, restore any broken system files/settings

If Big Linker virus is anything like other browser hijackers, it will be able to gather much more than just browsing history. Search inquiries, used apps, device/browser details, IP addresses, geolocations, and other browsing-related information can be collected.

Although these details are considered non-personal information and are mainly used by advertisers to customize ads specifically for you, they could be misused if they fell into the wrong hands. But that's just the beginning of threats that this browser hijacker could cause.

Big Linker redirect could open a new tab out of nowhere. Thus forcing you to visit a site of its choice. Most PUPs advertise other shady websites, such as:

  • gambling,
  • fake updates,
  • scams,
  • malware,
  • porn,
  • gaming, etc.

These websites usually pay-per-click to the PUP operators for every sent forth user. Thus many techniques can be used to redirect people to them. Big Linker ads are one of them as the ad content might be completely different from where you'll end up if you click it.

An ad stating that you have to click it to receive a $50 discount for a new TV could redirect you to a fake update site where you'll be pushed to installed another PUP or to a portal with malicious scripts where hazardous infections could be installed automatically through drive-by downloads.

Therefore, you should consider Big Linker removal immediately before more harm comes your way. You can do that automatically by performing a full system scan with reliable and free anti-malware software such as SpyHunter 5Combo Cleaner or Malwarebytes and letting the security tools do the dirty work.

Security analysts[2] highly recommend another tool to repair any damage your device system files sustained and delete tracking cookies. After you remove Big Linker, run system diagnostics with the ReimageIntego all-in-one system optimizer to get your device back on track.

Avoid the most popular PUP distribution techniques

Browser hijackers, adware, unnecessary toolbars, and other potentially unwanted programs can be distributed in many ways. But the most popular one is through software bundles. To gain revenue, third-party software vendors include PUPs in packs with legitimate software.

Big Linker PUPBig Linker PUP is distributed through official web stores but can be downloaded in a more stealthy manner, like software bundles, deceptive ads, and alike

The trick behind this technique is fairly simple – all apps are preselected for installation. Thus if you rush through it by choosing the Recommended, Quick or Standard option, all of them are installed instantly, and your device becomes infected.

Although PUPs aren't as dangerous as malware,[3] they can still diminish your device's performance harshly. Avoid third-party software vendors by downloading apps directly from developers, or pick the Advanced/Custom mode when installing a bundle and deselect all untrustworthy, unwanted, unnecessary apps from installation.

Use reliable security tools to remove Big Linker virus

Each and every device that is regularly used on the internet should have proper protection. Anti-malware tools can block dangerous websites, prevent you from installing potentially unwanted programs, such as Big Linker browser hijacker and safeguard your devices from hazardous malware infections.

You will need such tools to remove Big Linker from your affected machine. Launch it and scan the entire system. Agree with whatever the security tool recommends getting rid of.

How to prevent from getting browser hijacker

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
