yes. I use V1.6.5, 2018-07-03

I'll post a new release soon which should fix that. I'll let you know.

nope:
Code:
Downloading hosts file to: D:\PS-AdBlock\DL_Cache\54_source-hosts.txt
---> !!! Source "https://zerodot1.gitlab.io/CoinBlockerLists/hosts_browser" seems to be offline !!! <---
Trying next one...

Code:
nslookup zerodot1.gitlab.io 1.1.1.1
Server:  one.one.one.one
Address:  1.1.1.1

Non-authoritative answer:
Name:    zerodot1.gitlab.io
Address:  35.185.44.232

Hmm, ok next try. please post the output from following commands in PowerShell:

Code:
[Net.ServicePointManager]::SecurityProtocol
[Net.SecurityProtocolType]
[enum]::GetNames([Net.SecurityProtocolType])
Then try the following command which forces current PowerShell session to use TLS 1.2 (so, this is a temporary change only, no worries):

Code:
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12

After that, run the PowerShell script from the same PowerShell console and see if it succeeds this time.

There's any Error Message displayed, or something like that? Or is just like in previous comments where you receive an error about the source being offline?

I ask as I periodically run this script, and pull quite a few sources from that domain, and have no problems at all.

Ok... Uhm, can we try something?

(DISCLAIMER: I'll apologize beforehand for the wall of text)

Could you run the following code on a Powershell console, and see if it returns any message?:

Code:
try { (New-Object System.Net.WebClient).DownloadFile("[LINK]", "test.txt") } catch [System.Net.WebException], [System.Exception] { Write-Warning $Error[0] }

That snippet of code is basically the same as the one internally used on the PS_AdBlock.ps1 file, but slightly modified to return the actual error message. It's a simple try..catch clause that attempts to do something (whatever is inside the try), and in case that something goes wrong, it does whatever is inside the catch part.

So, inside those "sections" we have the following:

  • (New-Object System.Net.WebClient).DownloadFile("[LINK]", "test.txt") - This attempts to download the hosts file, and save it as test.txt (without quotes). PLEASE REPLACE [LINK] with the correct URL for the host file that you are trying to download, and keep the quotes, those are required. Please note that, as far as I have tested, the test.txt file is saved on your local profile (i.e. C:\Users\YOUR_PROFILE), and although it could be not the ideal, for testing purposes it's somewhat irrelevant.

  • Write-Warning $Error[0] - This writes, or displays, the actual error message on the Powershell console.

That should either give us a more detailed error message, and therefore, a better idea what's going wrong on your end, or it should be able to download the file.

Using that syntax, the error message should be displayed something like this:

Code:
PS C:\> try { (New-Object System.Net.WebClient).DownloadFile("https://raw.githubusercontent.com/greatis/Anti-WebMiner/master/hosts_", "test.txt") } catch [System.Net.WebException], [System.Exception] { Write-Warning $Error[0] }
WARNING: Exception calling "DownloadFile" with "2" argument(s): "The remote server returned an error: (404) Not Found."

In that example, I modified the file to download, adding an underscore at the end of the name of the file (hosts_) to force a "Not Found". The error message was printed below the try..catch, and it clearly states that the remote server returned an error message.

I am hoping that something like that (although not the very exact message) would be displayed on your end, and that could give us any idea about whats going on.

Please let me know if you have any questions.

Kind regards.

Code:
WARNING: Exception calling "DownloadFile" with "2" argument(s): "The request was aborted: Could not create SSL/TLS secure channel."

it worked after adding
Code:
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12

so I added it on top of the PS_AdBlock.ps1 and it finally worked,
the previous url still doesn't work though:
Code:
PS C:\Users\xxx> try { (New-Object System.Net.WebClient).DownloadFile("https://zerodot1.gitlab.io/CoinBlockerLists/hos
ts_browser", "test.txt") } catch [System.Net.WebException], [System.Exception] { Write-Warning $Error[0] }
WARNING: Exception calling "DownloadFile" with "2" argument(s): "The request was aborted: Could not create SSL/TLS
secure channel."

anyway I download this one manually

edit: I never received a quote notification (email) like I used to, maybe these stopped?
and they only work through the app?
I tried once to install this famous app and it was bs, play store rating of 1.8 says it all I think,
please bring back tapatalk guys, or at least enable email notifications for quotes!

@patrickdrd

Hey there,

Glad to hear that at least part of the issue was solved.

Now, based on you previous comments, can we try something else?

I was taking a look at that error, and I found this StackOverflow answer which, basically, expands a little further what you have already done. So, instead using [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12, you could use

Code:
[Net.ServicePointManager]::SecurityProtocol = "tls13, tls12, tls11, Ssl3, Tls"

(Please note that I'm adding Ssl3, Tls at the end as this was already present on your system, as per your previous comment)

Based on my current configuration (see below), I think that such configuration change could be helpful on your issue, as I haven't had any issues while downloading the hosts file from Gitlab (I did a test a few moments ago).

Code:
PS C:\> [System.Net.ServicePointManager]::SecurityProtocol
Tls, Tls11, Tls12

Hope that helps.

Kind regards,

@araxhiel nope :(

Code:
PS C:\Users\xxx> [Net.ServicePointManager]::SecurityProtocol = "tls13, tls12, tls11, Ssl3, Tls"
PS C:\Users\xxx> try { (New-Object System.Net.WebClient).DownloadFile("https://zerodot1.gitlab.io/CoinBlockerLists/hosts_browser", "test.txt") } catch [System.Net.WebException], [System.Exception] { Write-Warning $Error[0] }
WARNING: Exception calling "DownloadFile" with "2" argument(s): "The request was aborted: Could not create SSL/TLS secure channel."

meanwhile I'm having trouble whitelisting the script in kaspersky,
I tried whitelisting powershell.exe, PS_AdBlock.ps1, nothing :(
I'm getting "Trojan.Win32.Hosts2.gen" alerts when downloading is about to start and
I have to click twice (!!) in order to start,
I'll post on their forum as well

Damn, @patrickdrd , that's not good... I can't think on anything else to try to fix that, as it seems that there's some "funny" stuff going on on your end/environment. I'm sorry not being able to help you further (or, at least not until I can think on something else, or find more info).

And yeah, I remember those Kaspersky errors LOL - IIRC the error itself is not against Powershell, or the script itself, but against the host file.

I can't remember right now the exact root cause for that, but I hope that you'll be able to find a solution (I used to have that issue some years ago, and have moved on from Kaspersky as it was causing me a lot of other issues with BT devices).

it seems that the gitlab issue was a url issue,
I changed it from
Code:
https://zerodot1.gitlab.io/CoinBlockerLists/hosts_browser
to
Code:
https://gitlab.com/ZeroDot1/CoinBlockerLists/-/raw/master/hosts_browser
and it worked,
also kaspersky support replied that they acknowledged the false alarm and they will have fixed it by tomorrow,
so all issues resolved :)
thanks for your help @araxhiel

Hey @patrickdrd ,

Glad to hear that the issue is now solved. Awesome! Also it's great that the Kaspersky's team gave a helpful reply/solution, that's nice.

And, woah, that's a pretty weird thing, the URL change... Oh well, while it works, it should be cool LOL

Have a great day (or rest of the day).

Kind regards.

what if i want to restore my pc to origial state with add. pls guide
Hi there

Simply head to "C:\Windows\System32\drivers\etc". There you should find multiple "hosts" files:

- "hosts" - the current one which should be much larger in size than the others
- "hosts.old" - the previous version of your current "hosts" file
- "hosts.original" - a replica of the original file

All you need to do is:
1. Delete the current "hosts" file
2. Rename "hosts.original" to "hosts"
3. A prompt will appear, something like "if you change a filename extension, the file might become unusable, are you sure?" - hit "yes"

    Introduction
    Dear community

    This is my very first XDA: DevDB project. I'm glad to announce my ad-block solution purely based on PowerShell.
    I've been (and I still am) using AdAway on my Android phone. It's a great app, and it inspired me to get a similar solution for Windows computers.

    Version 0.1 was not public because it was slow as hell. It took about 8 minutes to handle ~200'000 hosts.
    With version 1.0, my script got a massive speed improvement. Now its duration has been greatly decreased. I achieved the same amount of hosts in less than 100 seconds now. But of course, these measured values shouldn't mean a lot, as they depend completely on your hardware (and a little bit on your internet connection of course).

    Now version 1.6 has an automatic backup & apply routine, check it out!

    Features
    This script does exactly what you think: It grabs various "hosts" sources from the internet, saves them locally, and merges them to one big file. Enjoy an ad-free Windows experience.

    • Download as many "hosts" files as you want
    • Merge them automatically into one big "hosts" file
    • Remove duplicates from the "hosts" file
    • Remove any comment line starting with # to keep your hosts file as small as possible
    • Apply a custom whitelist or even custom blacklists
    • Log the entire process to a log file (placed within the same directory where you saved this script)

    Disclaimer
    Altough this is normally a safe process, I am not responsible for possible damage to your device if anything should fail.
    I will not take any responsability for bricked Windows installations, other software defects or even lost data.

    License/forks
    This work is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License( ).

    This is an open source project, it's a PowerShell script and you're able to see the source code of course. You're allowed to modify this script as you want, as long as you give credits to me. Adaptations of my work shall be shared as well under the same license. Commercial use is allowed, as long as you don't sell my work.

    Requirements
    There are some requirements to check.
    • A little bit of PowerShell-knowledge (not necessary of course)
    • At least Windows 7 (theoretically it should work on any Windows)
    • At least PowerShell 3.0 (PowerShell 2.0 may work, but is unsupported)
    • At least 50 MB free space for this script
    • Administrative privileges - required if you want to use the automatic backup & apply routines, not for the script itself, otherwise you'll need to manually copy the "hosts" file into the Windows directory

    Instructions for use with administrator privileges (recommended)
    1. Download the archive and unzip it anywhere
    2. Execute the "_Run_Admin.bat" script via double-click, confirm the UAC window by clicking on the yes button and wait for the console to close itself
    3. Reboot your machine and enjoy an ad-free Windows experience
    4. Note: Instead of the batch script you can use the .ps1 file as well (unblock it first, simply right-click the .ps1 file, choose "Properties", then hit the "Unblock" button), start a new PowerShell console as administrator and manually run the script

    Instructions for use without administrator privileges
    1. Download the archive and unzip it anywhere
    2. Execute the "_Run_User.bat" script via double-click and wait for the console to close itself
    3. Copy the newly created "hosts" file and rename the existing "hosts" file to manually create a backup
      Code:
      C:/Windows/System32/drivers/etc/hosts
    4. Reboot your machine and enjoy an ad-free Windows experience
    5. Note: Instead of the batch script you can use the .ps1 file as well (unblock it first, simply right-click the .ps1 file, choose "Properties", then hit the "Unblock" button), start a new PowerShell console and manually run the script

    Instructions to customize psAdBlock
    1. To modify the "hosts" sources, simply edit the file "hostslist.ini"
    2. To allow specific hosts, simply edit the file "whitelist.ini"
    3. To block specific hosts, simply create a new .txt file within the "DL_Cache" folder and add the hosts (one per line) you want to block (e.g. "0.0.0.0 place-any-site-here.com")

    Credits & thanks to
    * Makorus: Creator of this PowerShell script
    * Dominik Schuermann: Inspiring me to do this
    * Luca Sturlese: Allowing us to use his awesome logging function library

    Any questions or suggestions? Did you find any bugs? Thanks for your feedbacks in advance! :good:

    ## - If you disable the backup/apply mode you have to manually copy the final          ##
    ##   'hosts'-file to the Windows etc directory (please manually backup the old file:   ##
    ##   C:\Windows\System32\drivers\etc                                                   ##
    ## - To apply a custom blacklist, simply create a text file containing your desired    ##
    ##   hosts and save it in the download cache folder 'DL_Cache' (run the script once)   ##
    ## - To manually add your custom hosts list, create a new text file called             ##
    ##   'hostslist.ini' and add your hosts sources (one site per line without the www)    ##
    ## - To automatically remove specific sites from the hosts list, create a new text     ##

    ## - The file now checks for the client DNS Cache service and logs a warning if it's   ##
    ##   enabled to ensure you don't run into troubles                                     ##
    ## - Removed the note about the DNS Cache service: It's not recommended to set the     ##
    ##   startup type to "demand" (manual), it will cause issues sooner or later           ##
    ## - Starting from now on, I'll create an executable file (to be found in the ZIP)     ##
    ## - I'll also attach a VirusTotal.com scan to every new release                       ##
    ## --> Please report any Anti-Virus false positive alarms to me                        ##

    ## V1.5.1, 2015-08-11                                                                  ##
    ## - Fixed issue with wrong $PSScriptRoot variable when using the EXE variant          ##
    ## - Changed the 'release history' to allow better versioning (e.g. version 1.5.1)     ##
    ## --> Note: Older versions still contain two numbers only (e.g. version 1.2 etc.)     ##
    ##-------------------------------------------------------------------------------------##
    ## V1.5.2, 2015-09-13                                                                  ##
    ## - Remove every empty line in the hosts file                                         ##
    ## - Changed the Log-Write function to use Write-Host instead of Write-Debug, now      ##
    ##   the entire log will be shown during the script execution (live)                   ##
    ## - Changed replacement method to insert 0.0.0.0 instead of 127.0.0.1 in the final    ##
    ##   hosts file which leads to a much better and faster DNS resolution                 ##
    ## - Future releases will be delivered with additional hosts files, for example to     ##
    ##   block Google ad servers and some Windows 10 hosts to stop this privacy nightmare  ##
    ##-------------------------------------------------------------------------------------##
    ## V1.5.3, 2015-10-08                                                                  ##
    ## - Fixed ugly encoding issue, new 'hosts' file will be created correctly now, means  ##
    ##   no BOM (Byte Order Mark) and no UCS-2 encoding anymore, should fix many issues    ##
    ##-------------------------------------------------------------------------------------##
    ## V1.5.4, 2015-10-09                                                                  ##
    ## - Fixed duplicate hostname issue, cmdlet Get-Unique allows by default hostnames     ##
    ##   with capital letters (Get-Unique is a case sensitive search)                      ##
    ##   e.g. 'test.com' and 'Test.com' are being handled correctly now                    ##
    ## - Reverted warning about DNS cache service, there should be no issue with the DNS   ##
    ##   cache service because the 'hosts' file is being encoded as a typical UTF8 file    ##
    ## - Added new debug mode, set $DebugMode to $true to activate it                      ##
    ##   This skips the download process, useful if you want to test something without     ##
    ##   re-downloading the whole host source lists                                        ##
    ##-------------------------------------------------------------------------------------##
    ## V1.5.5, 2015-10-10                                                                  ##
    ## - Fixed issue with method ToLower (should work with PowerShell 2.0 now), ToLower    ##
    ##   is a method to work with strings only, work around with a ForEach-Object cmdlet   ##
    ## - Added a PowerShell version check, unsupported versions are PowerShell v1 and v2,  ##
    ##   if you start this script with an unsupported PowerShell version, you'll find      ##
    ##   some hints in the log file to inform you about that                               ##
    ##-------------------------------------------------------------------------------------##
    ## V1.5.6, 2015-10-11                                                                  ##
    ## - Added again regex patterns to patch table, whitelist should work now correctly    ##
    ## - Debug mode now skips the patch process as well                                    ##
    ##-------------------------------------------------------------------------------------##
    ## V1.5.7, 2015-10-17                                                                  ##
    ## - Completely replaced previous regex patterns with one more complex pattern to      ##
    ##   handle hostnames with subdomains, performance increased significantly             ##
    ##-------------------------------------------------------------------------------------##
    ## V1.5.8, 2016-01-03                                                                  ##
    ## - Non-public test version only (skipped)                                            ##
    ##-------------------------------------------------------------------------------------##
    ## V1.5.9, 2016-01-24                                                                  ##

    FAQs
    • How to execute this PowerShell script?
      Option 1: Run the script using one of the included batch scripts, either the "_Run_Admin.bat" or the "_Run_User.bat" batch script.
      Option 2: Manually run the PowerShell script. But at first, you have to unblock the PowerShell script because it is a script you downloaded from the internet. Once you unzipped the file, do a right click on the PS1 file and open its file properties. Click on the "Unblock" button and you're done. Right click the file and click on "Run with PowerShell".
    • Why do I get an message warning me about an execution policy?
      Microsoft implemented this security feature when they published PowerShell. By default, the execution policy is set to "restricted", which means no scripts can be executed directly. You're able to configure the execution policy as you want. There are several execution policies, you can check them out here: Microsoft TechNet, Set-ExecutionPolicy.
      I personally recommend to change the execution policy to "unrestricted", this means you can execute scripts you created and even those you downloaded from the internet (though you have to be careful what you download and what you execute).
    • How to uninstall this PowerShell script?
      Basically, you just have to navigate to this folder:
      C:\Windows\System32\drivers\etc
      Delete the new hosts file and restore the original one by renaming "hosts.original" to "hosts" without any extension. After that, simply delete the files you downloaded from this thread.

    A late happy new year to everyone! :)

    I just released version 1.6.3 with a few small changes.

    I'm gradually moving this project completely to GitHub, therefore there's no need for an additional VirusTotal scan. Downloads will be moved to GitHub from now on. Contribution to this project is now even easier. :)

    Thanks for this great tool. Works great but can someone make an .exe out of it? It would be more convenient.


    Hi there, thank you for your reply. I can compile an EXE file out of it, but I expect a lot of false reports from anti-virus applications. I'll upload the EXE file tomorrow.

    Kind regards
