Remove Default Search virus (Removal Guide) - Free Instructions

removal by Julie Splinters - - | Type: Browser Hijackers

Default Search virus – a browser hijacker that might take over your Google Chrome or another web browser

Default SearchDefault Search is a potentially unwanted application that is difficult to eliminate

Default Search is a potentially unwanted application[1] that typically arrives on the system unexpectedly and changes the settings of the installed web browser. Besides setting homepage address to find.defaultsearch.info and appending a customized search engine, the virus also appends the “Managed by your organization” status to Google Chrome, Mozilla Firefox, Safari, or another web browser.

Due to browser hijacking practice, users are forced to use a customized search engine, which pulls all search results from Yahoo and injects sponsored links into them. In other words, if you are using Default Search as your main provider, you will be shown ads at the top of search results, whether you like it or not. It is also important to note that the PUP secretly gathers information about users' online habits and shares it with third-parties for more profits.

Name Default Search 
Type Browser hijacker, potentially unwanted program
IP address 195.154.42.103 
Distribution Software bundles, deceptive ads, fake updates, third party websites
Symptoms Unknown extension or application is installed on the system; homepage and new tab address are set to find.defaultsearch.info; a customized search engine is applied; search results are filled with sponsored links; overall increased amount of advertisement
Risks Installation of other potentially unwanted programs, information disclosure to unknown parties, financial losses
Removal You can uninstall potentially unwanted programs by following the manual guide below or by scanning the computer with powerful anti-malware
Optional steps Computer infections can cause significant damage to system files or disrupt default or user-set settings. To revert these changes and remediate the OS, perform a full system scan with ReimageIntego repair software

As mentioned in the introduction, the Default Search virus typically shows up on the system uninvited – users find it one day when they open their web browser. While it is widely believed that such apps simply install themselves, it is not true at all, and it is a consequence of users' actions.

Most commonly, software bundling is at fault – a deceptive marketing technique that allows offering optional components within a single installer. Nonetheless, the Default Search browser hijacker can also be installed through other means, as some PUPs are delivered through legitimate sources (such as Google Chrome web store), or fake update prompts for Flash Player or other popular software.

Instead of seeing the regular Google.com or another provider that they have chosen, users will quickly see that all the searchers are being redirected to Yahoo. While it is a legitimate search provider, and that is precisely where the results are pulled from, it has nothing to do with the Default Search hijack. The hijacker authors simply participate in the company's affiliate program, where almost anyone can enroll. If you prefer Yahoo, simply set it as your default engine, so you can avoid unwanted ads being shown to you constantly.

It is also important to note that the Default Search virus gathers various info about users who have it installed. For example, the following data might be collected, shared, or sold:

  • IP address
  • Internet Service Provider (ISP)
  • Unique device identifiers
  • Search terms
  • Browsing history
  • Links clicked, etc. 

The app belongs to a broader family of potentially unwanted programs that set the “Managed by your organization” setting on the web browser, preventing an easy Default Search removal. The feature, which is also used by Custom Search, Comet Search, and Mazy Search, is typically used by corporations to set restrictions to certain workstations and is not meant to be used by browser hijackers. With the help of this setting, developers can receive profits from pay-per-click and other schemes as long as the app is installed on the system.

This creates a rather frustrating experience for end-users, however, as not only they have to deal with altered browser settings, inability to find relevant information, and background data tracking, but are also unable to remove Default Search virus easily.

Since the PUP typically comes as an extension, its termination can be performed when it is removed from the web browser. For more information on that, please check the bottom section of the article. Keep in mind that if you found the PUP on your machine seemingly out of nowhere, there could be other threats that are invisible to you. Thus, you should scan your computer with anti-malware (such as SpyHunter 5Combo Cleaner or Malwarebytes) and then repair virus damage with ReimageIntego.

An easy way to prevent PUP installation

As already explained, potentially unwanted programs arrive on the system seemingly out of nowhere. Stealthy distribution mechanics are very common among PUPs – that is precisely one of the reasons for their name. Most commonly, such apps provide very little to no benefit for end-users and sometimes might even posses malicious qualities (for example, scareware[2] apps attempt to intimidate users by showing fake scan results about the system's health to make them purchase the license, which seemingly then removes all the bogus problems).

Thus, it is always a good idea to avoid browser hijackers, adware, and other suspicious programs. Here are some tips from experts:[3]

  • Always download apps and their updates from official sources;
  • When dealing with third-party websites, be aware that software bundling is extremely common;
  • Never download anything from sites that offer pirated software or cracks, as you could infect your machine with threats like Mmpa ransomware;
  • Research the app you are about to install – read forum posts, user reviews, etc.;
  • Always pick Advanced/Custom settings during the installation instead of Recommended/Quick ones;
  • Install powerful security software that would detect and warn you about PUPs and malware.

Wondering how to remove Default Search virus? Follow these steps

Many users start searching for Default Search removal instructions, as they cannot do so in a regular way. Since the app comes as an extension, all you would have to do usually would access the settings of your web browser and delete the extension that hijacked it. Unfortunately, the setting to delete the add-on is usually grayed out. Thus, the first thing you should do is reset your web browser – we explain how below.

If you are unsuccessful, you should go to the following location on your machine and delete the “Google” folder:

C:\Users\[username]\AppData\Local

This should allow you to remove Default Search once and for all. If still no luck, however, you should employ SpyHunter 5Combo Cleaner, Malwarebytes, or another anti-malware that would do the job for you. In case your machine is having issues after all the malware and PUPs are deleted, you can attempt to fix virus damage with ReimageIntego.

You may remove virus damage with a help of ReimageIntego. SpyHunter 5Combo Cleaner and Malwarebytes are recommended to detect potentially unwanted programs and viruses with all their files and registry entries that are related to them.

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.
