URL:Blacklist (Blacklisted URL) Avast Detection

Written by Wilbur Woodham
Avast Antivirus or AVG actively utilizes the detection name “URL:Blacklist” to identify URLs linked to malicious websites or phishing scams. When Avast identifies a URL as blacklisted, it instantly prevents access to that site, thereby shielding users from potentially harmful content.


URL:Blacklist is a detection term used by antivirus and security software to indicate that a specific URL or web address has been added to a blacklist. Blacklisting is a common cybersecurity technique used to block access to known malicious websites or URLs that are associated with phishing, malware distribution, or other cyber threats.

When a URL receives the URL:Blacklist flag, it indicates that the website connected to that specific URL has been reported or recognized as a source of malicious activity. Accessing such websites might pose risks to the user’s computer or data. Consequently, web browsers, antivirus software, and other security tools utilize URL blacklists as a preventive measure, effectively blocking access to these dangerous websites and ensuring users’ safety from potential threats.

Malicious websites serve as conduits for distributing malware and unlawfully collecting personal information from unsuspecting individuals. Conversely, phishing scams aim to deceive users into disclosing sensitive data, such as usernames, passwords, or credit card numbers.

To safeguard yourself against malware and various online threats, it is of utmost importance to rely on trusted anti-malware software, consistently update your operating system and other software, and exercise caution when interacting with suspicious links or downloading files from unfamiliar sources. By adhering to these practices, you can significantly bolster your online security and protect your valuable data from potential cyber-attacks.

What does URL:Blacklist detection mean?

Avast or AVG presents the URL:Blacklist detection message displayed in the lower right corner. While these anti-malware programs are generally proficient in scanning, they are known to be somewhat unreliable and susceptible to malware attacks. Their user interface can be glitchy, and their ability to effectively remove malware can be problematic. Consequently, the pop-up indicating the presence of URL:Blacklist should be regarded as an alert rather than a reliable solution. To effectively eliminate it, it is advisable to utilize an alternative anti-malware program.



The URL:Blacklist virus is an extremely troublesome entity. It infiltrates your system under the guise of something seemingly innocuous, often disguising itself as a legitimate component or an application obtained from a forum. Once inside, it takes various actions to weaken your system’s defenses. To make matters worse, it proceeds to download additional malicious elements, fulfilling the desires of the cyber criminals who control this virus. As a result, predicting the exact consequences of URL:Blacklist’s actions becomes nearly impossible, and unpredictability is one of the most concerning aspects when it comes to dealing with malware. It is therefore highly advisable to avoid encountering this virus altogether, denying it any opportunity to carry out its malicious objectives.

Is URL:Blacklist dangerous?

As I have stated previously, non-harmful malware does not exist. And URL:Blacklist is not an exclusion. This virus changes the system configurations and modifies the Group Policies and Windows registry. All of these things are critical for correct system operation, even in cases when we are not talking about system security. Therefore, the virus that URL:Blacklist carries, or which it will inject after some time, will try to get maximum profit from you. Cybercriminals can grab your personal information and then sell it on the black market. Using adware and browser hijacker functionality embedded in URL:Blacklist malware, they can make money by showing you the ads. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners daily – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.

How did I get this virus?

It is difficult to trace malware’s origins on your PC. Nowadays, things are mixed, and spreading ways utilized by adware six years ago may be used by spyware these days. But if we abstract from the exact spreading method and will think of why it has success, the explanation will be really simple – low level of cybersecurity knowledge. People click on ads on weird websites, open the pop-ups they get in their browsers, and call the “Microsoft tech support,” thinking that the odd banner that states about malware is true. It is necessary to recognize what is legit – to avoid misconceptions when attempting to identify a virus.

Microsoft Tech Support Scam

Nowadays, there are two of the most widespread ways of malware spreading – lure emails and injection into a hacked program. While the first one is not so easy to stay away from – you must know a lot to recognize a counterfeit – the 2nd one is simple to solve: do not use cracked applications. Torrent trackers and various other providers of “totally free” applications (which are, in fact, paid but with a disabled license checking) are a giveaway place of malware. And URL:Blacklist is just among them.

How to remove the URL:Blacklist from my PC?

URL:Blacklist malware is complicated to erase by hand. It places its files in several locations throughout the disk and can get back itself from one of the elements. In addition, a range of alterations in the windows registry, networking settings, and Group Policies are really hard to locate and revert to the original. It is far better to utilize a specific program – exactly, an anti-malware app. GridinSoft Anti-Malware will fit the most ideal for malware elimination purposes.
