Title: How to remove: URL: Blacklist ?
Post by: multu40200 on August 16, 2020, 01:11:10 PM
Morning, everyone!

I've been using your antivirus for over 10 years now, except that for the first time today it prevents me from accessing a site I visit every week.

Indeed, when I go to the notube.net site, I get an access error and Avast opens by saying: URL:Blacklist. Yet the site is reliable and has been working for several years.

Is it possible for you to remove the domain from your blacklist?

Also, is it possible for me to fill in the "false positive" form even if I am not the author of the site? What would be the resolution time?

I use this site every week for video editing, it saves me from downloading an application but it's very embarrassing not to be able to go there!

Thank you in advence

Ah yes, in English it works, but if you try it in French: htxps://notube.net/fr/start-converter - then you'll get blocked.

Having this same issue. Is there any way to edit the blacklist locally? Adding an exception to the webshield doesn't work, even wildcarding the end of it. Like it was said above, i'd hate to have to change to a different antivirus over such a prepotent posture over a very, very simple concept.

Wait for a final verdict from avast team. Only avast team members can come and unblock or state it is an FP,
we here have relevant knowledge but cannot.

Question therefore remains is that site still being compromised?

It's showing Phishing because of IP address, later I moved website to another server. Now everything is okay but still because of old IP address it shows Phishing warning by Avast.

There are three Word Press CMS related issues with this site, that needs addressing:

1. & 2. Outdated Word Press plug-ins detected:
   -accordions 2.2.32   Warning   latest release (2.2.34)
https://www.pickplugins.com/item/accordions-html-css3-responsive-accordion-grid-for-wordpress/

strong-testimonials 2.51.5   Warning   latest release (2.51.6)
https://strongtestimonials.com

3. User Enumeration
The first two user ID's were tested to determine if user enumeration is possible.

Username   Name
ID: 1   admin   admin
ID: 2   not found   
It is recommended to rename the admin user account to reduce the chance of brute force attacks occurring. As this will reduce the chance of automated password attackers gaining access. Take note that if the author archives are enabled it is usually possible to enumerate all users within a WordPress installation.

Site speed is under par.

A more extensive report here: https://www.immuniweb.com/websec/kaambesh.com/0krSxIs4/

Virus Total relations states that AS was involved in mail.phishing and Trickbot abuse.

We have right away identified the issue, banned the user and hardened our security which makes it totally impossible to do so again ever since. Btw Other sites are fine.

Thank you!!

First please modify your url so it isn't active (avoiding accidental exposure) as we have done in the quoted urls.

There are some other things you might consider from checks on the domain:
Some hardening - https://en.internet.nl/site/twilead.com/1739533/
Also blacklisted here - https://sitecheck.sucuri.net/results/twilead.com
Webpage Security Score E - https://snyk.io/test/website-scanner/?test=221013_BiDcWE_97M&utm_medium=referral&utm_source=webpagetest&utm_campaign=website-scanner
Outdated software also reported here - https://awesometechstack.com/analysis/website/twilead.com/

Whilst these may or may not have been the reason being blacklisted by Avast - addressing these could make it harder to exploit.

Hi Leontius Marius,

Additionally to what DavidR and bob3160 have been reporting, just take notice of the following issues.

Avast is not alone here, see: https://urlscan.io/result/be44819e-389c-45cd-b284-ae7840f19458/
Verdict Potential Malicious & Malicious Activity detected.

Mentioned as being phishing against facebook.
And website is still being flagged by Avast as I come to write this.
Wait for an avast member's final verdict, as they are the only ones to come and unblock.

Also look here for so-called (suspicious) indicators -> https://urlscan.io/result/be44819e-389c-45cd-b284-ae7840f19458/#indicators

the website newsnet.ro is created on an OxWall platform.  the plugins are bought from OxWall, we have license keys for all of them, including the facebook login plugin which I have disabled now.  we have no frauds, newsnet is the official social network of the Evangelical Protestant Church in Romania and I am admin.  what Avast is doing is blackmailing us by labeling it as a "fraudulent website". On Monday, if the antivirus continues to categorize it as a virus website, I will also file a criminal complaint with the Romanian Police and the FBI both against Avast and against the others  people who own websites where we are maliciously labeled. No one makes fun of our work and the church network. Both the Romanian law, the German law and the American law expressly prohibit false statements in public computer data. The Romanian law punishes with  prison for such acts. we live and use newsnet especially in Romania and the law protects us. we will fight for every day of arrest of those who caused us this harm, because even after my warning things have not changed.  And attention, I am the coordinating pastor of the Religious Group of the Evangelical Protestant Church in Romania. Avast, you will have to pay millions of euros for what you did to us. Remember: Monday morning  today, 8 o'clock in Romania, you have a maximum deadline

How is avast blackmailing you, they haven't demanded money from you.

Considering your site as you said is the  "official social network of the Evangelical Protestant Church in Romania" a religious based one, these threats are hardly compatible.

We Avast Users have given you information on:

It can also be reported as a possible False Positive, links already given in this topic several times.

Title: Re: How to remove: URL: Blacklist ?
Post by: aaronavcrc on November 19, 2022, 06:40:02 PM
Is there a way to see the list of addresses in the "URL:Blacklist"? I was in the middle of launching a game and it gave me a URL blocklist error and the game crashed. I attempted to reload the game and now it does not prompt me with the URL:Blacklist msg. I turned off active AV and it worked until the 10 min timer was done and then it locked up and the game crashed again. Please help me find the URL in question so I can file a false positive report.

Thank you,

Did you check the url against VirusTotal. Do other vendors block it as well.
You could post a FP notice and wait for a reply from avast team.
