Block Access Site adware Removal Guide

What is Block Access Site adware?

Block Access Site is a bogus browser extension that acts as adware when installed

Block Access SiteFake browser extensions can cause unwanted pop-ups and redirects

Block Access Site is a bogus browser extension that acts as adware.[1] It causes an increased amount of commercial content, like pop-ups, banners, and redirects. It is advertised as an extension that blocks access to websites to increase productivity. The pop-ups may appear even when the browser is closed.

The main purpose of such applications is to generate revenue from pay-per-click advertising. They may also use rogue advertising networks[2] that place ads leading to dangerous websites. By clicking on links embedded in the ads, people may end up on scam pages that try to lure out personal information, trick people into downloading PUPs (potentially unwanted programs),[3] and even malware.

Usually, users start seeing ads promoting fake antivirus programs, software deals, adult websites, surveys, giveaways, and dubious dating platforms. If there is anyone else using the affected machine, especially children, it is important to remove this intruder as soon as possible.

NAME Block Access Site
TYPE Browser hijacker; adware
SYMPTOMS The extension starts generating intrusive advertisements and may change the main settings
DISTRIBUTION Shady websites; deceptive ads, freeware installations
DANGERS The ads may lead to dangerous websites controlled by crooks who try to take advantage of less IT-savvy users
ELIMINATION Remove the extension through browser settings
FURTHER STEPS Use ReimageIntego to clear your browsers and fix any remaining damage

Distribution methods

The Block Access Site is being promoted on a website that falsely claims the Chrome browser is out of date and offers to update it. The plugin is added to the web browser after completing the steps provided on this suspicious website. The fake Block Access Site extension has also been found on shady download pages. These “Downloader” sites are often found on websites that engage in illegal activities and are full of deceptive ads and sneaky redirects.

Google has stated that they will remove fake “Download” and “Play” buttons, but they still exist. Fake “Downloader” pages often use social engineering tactics[4] to trick users into installing a browser extension to “continue to the website” or for “security reasons.” However, you should never have to install any plugins or programs to access content on a legitimate website.

To avoid falling victim to these scams, it is recommended to only use official web stores and developer websites when installing extensions. These apps go through an extensive review process before they are listed on digital marketplaces, but it's still important to do your own research, read reviews, check ratings, and look at the number of users.

Freeware installations

Adware is frequently spread through the use of freeware distribution platforms, which secretly bundle additional programs into the installer. Many people quickly skip through the installation process and do not notice these additional files. While purchasing software licenses may seem costly, it can save you money in the long run by keeping your system running smoothly.

To avoid inadvertently installing adware, it's important to always select the “Custom” or “Advanced” installation method, read the Privacy Policy and Terms of Use to understand how your data will be used, and carefully review the file list to uncheck any unrelated applications.

Protect your privacy

Websites, web-based applications, and programs can use cookies to track your activity. These small data files can store information like your IP address, geolocation, websites you visit, links you click on, and things you purchase online. This raises many user privacy and security concerns as this data can be sold to advertising networks or other third parties.

We recommend having a maintenance tool like ReimageIntego that can clear your browsers automatically. It can eliminate cookies and cache, and stop the tracking process. This powerful software can also fix various system errors, corrupted files, and registry issues which is especially helpful after a virus infection.

Scan your system with anti-malware tools

If you completed all the previous steps but you still experience unwanted symptoms, you should check your system for other PUAs. We suggest using SpyHunter 5Combo Cleaner or Malwarebytes anti-malware tools that will scan your machine, eliminate it, and prevent such infections in the future by giving you a warning before a PUP can make any changes.

Manual removal of potentially unwanted programs can sometimes result in the renewal of the infection as users often fail to eliminate all the related files and entries. Besides, crooks often disguise them as “handy” tools so it can be difficult to identify them. If manual removal is what you still prefer, we have instructions for Windows and Mac machines:

How to prevent from getting adware

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.
