What is a Uniform Resource Locator (URL)?
The Uniform Resource Locator (URL) is a format for specifying the World Wide Web addresses. A URL is the most basic network identifier for any site on the Internet (e.g., hypertext pages, images, and sound files). A URL is the Internet address of a particular, specified site. As a general rule, a valid URL points to a single piece of content.
For example, you may use an HTML page or a CSS file to create an image. A URL that no longer exists or has moved is the most typical exception to this rule in reality. Web server owners are responsible for maintaining the URL and the resource it represents since they are in charge of the URL and the URL itself.
What is a URL block list, and how does it work?
A URL blocklist is a list of URLs excluded from search engines’ and security programs’ indexes. If the website is deemed to be dangerous, these URLs are banned. They do so by locating diseased areas, which may be found in various structures. Phishing schemes, Trojan horses, spam, trolling, and so forth.
As a result, authorities and web indexes prevent people from advancing to the site and advising the website owner, blocking the attackers’ malevolent goals. Antivirus software, for example, can protect their clients’ computers by limiting access to websites notorious for spreading unauthorized software, drive-by downloads, and harmful payloads. (I’m just giving you an example.)
Google is the most critical block listing authority for website owners. Every day, Google’s Safe Browsing department looks after the well-being of more than 3 billion users through the organization’s range of services, which include:
- Google’s search engine
- Ads by Google
When Safe Browsing detects a potentially harmful website, it notifies the user and displays warnings in Google Search and Chrome.
What causes a URL to get blocked?
Search engines are committed to maintaining a high level of security by blocking any spammy websites. They devote efforts to detecting and alerting a rogue website that poses a significant hazard. So, here are a few methods for blocking a website:
- Unsafe plugins/libraries provide a backdoor.
- Vandalism to a website
- Schemes of phishing
- Trojan horses are a kind of horse that is used.
- Hacks in the pharmaceutical industry
- Spam in the SEO field

Why did Avast block a URL on my PC?
Avast Internet Security has a built-in firewall protecting your computer from viruses, malware, and spam. Avast Internet security can alert you if a dangerous URL or website is discovered when surfing the Internet. Real-time security is provided by the software, which operates when you are surfing the web or downloading applications and files.
An Avast pop-up shows if a lousy URL is discovered, informing you of the risk of harm or infection. Avast also sends virus definition updates to your computer when new infections are identified, ensuring that your machine has the most up-to-date security. Thanks to the built-in firewall, your computer is also protected from hackers and attempts to steal private and secret information.
Avast is one such antivirus application with an online spam detection mechanism that is both effective and quick. Avast’s Web Shield component is in charge of banning websites on your computer. Some of the reasons why the Web Shield Program could restrict a website are listed below.
- Scheme of Phishing
- Trojan Horses, to be precise.
- Scam involving a fictitious lottery or a credit card.
- Scams via email.
- Unwanted apps are being downloaded.
- Browser extensions that aren’t real.
- trackers on the Internet
If the website is confirmed to have such flaws, Avast Web shield will ban it and display a security warning that says Infected with URL: Blacklist. You can unblock it if you believe the website you’re attempting to access is secure, and Avast gives you a False Positive answer.
What are the signs when a website is blocked?
You may use many security check tools to see if a website or your website is blocked, such as:
Google Safe Browsing — the finest resource for identifying concerns with a website’s blocklist or health status.
UltraTools’ Domain Blacklist Check is a potent threat detection tool that can swiftly determine whether or not your site is secure.
Google Analytics is a reliable traffic measurement tool for determining how people move across your site. Remember that if you see a significant drop in online traffic, one of the critical causes might be your site being banned by Google and others.
How can I unblock a domain that has been blocked in Avast?
You may unblock a single website and remove it from the Blacklist rather than entirely deactivating the web shield and exposing your machine to other internet assaults. Avast will enable you to view the domains you add to the “Exceptions” list without any warnings or delisting.
Open the Avast interface and navigate Menu>> Preferences to unblock a blocklisted domain. Click on the Core Shield tab, then on the “Add Exceptions” option under “Web Shield” to add the exact URL/ Domain that you wish to unblock. We’re producing a thorough step-by-step instruction to unblock a blocklisted URL in Avast for better understanding.
Step 1: Open the Avast Security interface on your computer and select the menu option in the top-right corner. Select “Preferences” from the Menu after scrolling through the choices.
Step 2: Select “Core Shields” from the drop-down Menu and scroll down to the “Web Shield” option. Click the “Add Exceptions” button under Web Shield.
Step 3: In the Server URL box, type the URL you wish to remove from the Blacklist. Select both checks under “Web Server Services” and click the Add button.
Step 4: Close the software and launch Google Chrome or another web browser. Check to see if the website you recently unblocked is still accessible.
We hope you now understand what Infected with URL: Blacklist means in Avast and why the URL is blocked. It is usually advisable to avoid visiting websites that an antivirus product or Google Chrome has blocklisted. You’ll be protected from most internet cyber-attacks, and your system will be clean of trash files and malware if you do it this way.
