Keep Fast SearchKeep Fast Search changes the settings of users' browser

Keep Fast Search is classified as a browser hijacker because it changes the main settings, like the homepage, new tab address, and search engine. It adds keepfastsearch.com as a homepage and redirects users to search.yahoo. The web-based application may use various tracking technologies to collect data about users' browsing activities.

The main purpose of such apps is to generate revenue. There are several ways that this can be done. Such extensions can generate commercial content and receive payment every time you click on an ad[1] or it can collect data using cookies and then sell them to advertising networks or other third parties.

Usually, browser add-ons are meant to provide some kind of benefits to the user that a default browser cannot. People love extensions that can block ads, dangerous pages, or automatically search for coupon codes for the biggest discounts while shopping online. Unfortunately, this is not one of those plugins and there are no functions that could be deemed beneficial. You should remove it by using our guide.

NAME Keep Fast Search
TYPE Browser hijacker; potentially unwanted program
SYMPTOMS Changed homepage, new tab address, and search engine; redirects to suspicious websites; increased amount of commercial content
DISTRIBUTION Shady websites, deceptive ads, freeware installations
DANGERS The plugin may collect browsing-related data, redirect users to dangerous websites where they can get tricked into providing their personal information or downloading PUPs and malware
ELIMINATION Remove the extension via browser settings
FURTHER STEPS Use a repair tool ReimageIntego to clear your browsers and optimize the machine

The name Keep Fast Search implies that the plugin should provide faster-searching speed but that is not true. In fact, this plugin makes the searching process longer as it redirects users to a different search engine. Before you add an extension to your browser, prompts will pop up informing you about the changes that it will make. You should pay attention to that as you can avoid such infections in the future.

Distribution methods

Usually, these types of applications appear in users' browsers after they surf through shady websites. Often the developers of rogue extensions create separate promotional websites that encourage users to download them. Often they use deceptive methods to promote their products.

You may notice that a lot of these browser plugins are “Recommended by Chrome” or “Recommended by Google” or any other well-known company. Fraudsters use these messages to appear trustworthy and make users more likely to install the program. That is why you should always do your research before pressing the “Download” button.

Use official web stores as they are the safest because the extensions that get listed go through an extensive review process. You should also read the reviews, look at the ratings, and how many users it has. Although it is rare, some browser hijackers sneak through the review process and get listed.

You should definitely avoid freeware distribution sites as they are filled with PUPs (potentially unwanted programs)[2] and even malware. There is a possibility that the appearance of the Keep Fast Search is related to freeware installation as those sites often use software bundling[3] to make their activity worthwhile. Follow the removal guide below to identify the issue and take care of it.

We suggest using ReimageIntego maintenance tool to clear your browsers and to completely get rid of any remaining damage.

The software can optimize your device and improve performance by deleting all junk files that you do not need.

Cookies collected by various websites and web-based applications can also be used to make a profit by selling them to advertising networks or other third parties. There have also been instances when browser cookies were hijacked and used for malicious purposes so we strongly recommend deploying the repair tool to prevent this from happening.

Scan the system to detect adware

Identifying a PUA can be a complicating process if you do not have experience. Often crooks disguise these programs as handy tools to make them less noticeable.

If you are not sure what to do and you do not want to risk eliminating the wrong files, we suggest using SpyHunter 5Combo Cleaner or Malwarebytes security tools that will scan your machine, eliminate it, and prevent such infections in the future by giving you a warning before a malicious program can make any changes.

How to prevent from getting browser hijacker

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
