Blocksly browser extension Removal Guide

What is Blocksly browser extension?

Blocksly is a useless app for your browser that can generate revenue from browsing activity

BlockslyBlocksly may change the main settings of the browser

Blocksly is a bogus browser extension that changes the main settings, like the homepage, new tab address, and search engine. It can also cause an increased amount of commercial content, like pop-ups, banners, and redirects. Such apps are created for the purpose of generating revenue from pay-per-click advertising.[1]

The plugin is promoted as an “innovative ad protector” but in reality, it does not have any useful functions that are unavailable in a default browser. Crooks often try to make their apps look like “handy” tools to make users download them themselves.

Creating and distributing hijackers does not require any hacking skills. Fraudsters can program one application, and make multiple copies by changing the names. Users should know how to distinguish hijackers from legitimate web-based apps to avoid installing them. Read our guide below to learn more.

NAME Blocksly
TYPE Browser hijacker; potentially unwanted program
SYMPTOMS The main settings of the browser like the homepage, new tab address, and search engine get changed
DISTRIBUTION Shady websites, deceptive ads, freeware installations
DANGERS The app can lead to misinformation, dangerous pages, and collect browsing-related data
ELIMINATION Remove the plugin via browser settings
FURTHER STEPS Use a maintenance tool ReimageIntego to fix any remaining damage and optimize the machine

Security measures

To avoid browser hijacking in the future, we recommend staying away from shady websites that engage in illegal activities, for example, illegal streaming sites. You should also be careful and not click on random links online, make sure they are safe first.

You may also find that using official web stores and developer websites to get browser extensions and computer software is much safer. Apps that get listed on digital stores, go through a lengthy review process so you can be sure it is not a virus. Despite that, you should still do your research and read the reviews, look at the ratings, and how many users add-ons have. This will help you decide if they are trustworthy.

You can also follow simple steps during the installation process to avoid bundled software. Always choose the “Custom” or “Advanced” installation method, read the Privacy Policy and Terms of Use to find out what the program will be able to do in your machine and what data will it collect. The most important part is to look at the file list and untick the boxes next to those that seem unrelated or suspicious.

Blocksly browser extensionBlocksly is distributed through shady pages

In the picture above, you can see an example of a bogus “Download” page. When you see something similar appear, you should take a step back and analyze the site. On the browser tab, you can see the message “Browser update” and on the site itself – “Click Download and Install Recommended Chrome Extension.” As you might have already noticed, the message is not cohesive, and the text is full of grammar mistakes. You should never explore such websites and close them immediately.

Scan the system to detect adware

The hijacking could have been caused not only by a browser extension but also by a PUP (potentially unwanted program).[2] If the previous removal method did not get rid of unwanted symptoms, this step should fix it. Adware usually hides in the background of the machine performing unwanted tasks without the users' knowledge.

Most times adware gets installed from freeware[3] distribution sites. Because they do not make any money from giving away software for free, they include additional programs in the installers. Many users find the installation process boring so they skip through the steps and do not notice the additional files.

Identifying the program responsible for hijacking your browser might be difficult if you have never done this before. Fraudsters like to disguise them as “handy” tools, so they could look like an antivirus suite, image editing software, media player, system optimizer, etc.

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

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
