What sources are you using?
To solve:
Aktivate logging in adawy. Visit blocked sites. Go to log and long press the corresponding entry to add it to white list. Refresh, aktivate and reboot.

Now I'm confused. Do you have problems to get it working on a PC or on android? This here is for windows os PCs, yet you mentioned adaway which is for android. Please clarify.

Hi. windows pc.
some pages like news with payment wall which im subscribed to, wont load. but i must say this is random.sometimes it does load, i had no issues with this kind of behavior before running adaway, that's why i want to try and uninstall, and see if problems persist. i had to send previous msg here with my android, for i had trouble login xda with pc, but now it works. thank you for your patience and help.

Sorry guys, I've been very busy these days.

I just released version 1.6.1 of psAdBlock. It contains a very small change, I forgot to update the version number which lead to wrong version outputs in the log files. :p

I'll be busy for the next month as well, but I plan to start working on version 1.7.0 (maybe in June).
I just had an amazing PowerShell class where I could learn a lot. I want to rework version 1.7.0 as much as possible with my new PowerShell-knowledge. I'm sure this will be a lot of fun. :D

Are you guys experiencing any issues with this script? Are there any feature requests?

hosts file so small

Hello there!
I'm just wondering about something.
I just used your script to generate hosts files. It became ~1 MB
At the same time I generated one with adaway, and it is almost 2 MBs.
:insert BUT WHY gif: :D
First I tought maybe adaway left a lot of duplicates when merging the files, but with a brief search I did not found any, so I'm clueless.

---------- Post added at 07:54 PM ---------- Previous post was at 07:49 PM ----------

Thanks! It works perfectly fine.

If I would like to unblock all ads, what should i do?

To unblock all ads delete everything from hosts file and put in these two lines:

127.0.0.1 localhost
::1 localhost

Hi there

Are you sure you're using the same "hosts"-list sources? I just checked and my file being created on Windows is 2.5 MB. On my Android device, using the same "hosts"-sources I get (almost) exactly the same file. :)

On Android, I didn't bothered any setting so it's all on default...hmm..I checked now, and it is only listed four links. That's one error.
But with this script (1.6.1) I didn't change anything, so it checks 6 links.
Now I'm more confused than before :D

Why isn't there ONE big hosts file host? :rolleyes:

Try to compare the amount of lines and the amount of total characters. I assume the default AdAway list contains one "hosts"-sourcelist which is very big.
Or try to enable 2 lists on your Android device and enable the same lists on your Windows device and then compare again.

Thank you for this. This is great little tool.

@Makorus Hi, me again. You could use your .bat file to check for admin rights automatically. Like many users, I initially clicked on file without elevated privilegies.
Here is piece of code you can put at the top of the _run_script.bat ;)
Code:
@echo off
:: BatchGotAdmin (Run as Admin code starts)
REM --> Check for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"
REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
echo Requesting administrative privileges...
goto UACPrompt
) else ( goto gotAdmin )
:UACPrompt
echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs"
"%temp%\getadmin.vbs"
exit /B
:gotAdmin
if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )
pushd "%CD%"
CD /D "%~dp0"
:: BatchGotAdmin (Run as Admin code ends)
:: Your codes should start from the following line
It is not my brainstorming, I use it for few years without any issues. All credit goes to Evan Greene.
Good thing is that antivirus will not flag it as false positive so you could make a beta version to get some feedback.
Kudos, great stuff, keep it alive please.:good:

Damn man, many thanks for having created this. This and uBlock origin = killer combination on those sites that request you to disable the adblocker. By the way, does PSAdblock include Adaway's lists?

Great work!

I would like to know is it possible to add an option to run every time windows boots in background and replace hosts automatically?

Hi everyone, sorry for my very delayed reply! I've been very busy these days. I'll reply to you guys tomorrow as I'm travelling now.

To uninstall, simply delete your existing "hosts" file and rename "hosts.bak" to "hosts", reboot your PC afterwards. Let me know if it works.

Kind regards

    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)

    FAQs

    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")

    * 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:

    ## - 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                       ##

    ## - 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    ##
    ##-------------------------------------------------------------------------------------##

    ## - 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                                        ##

    ## - 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                               ##

    ## - Added again regex patterns to patch table, whitelist should work now correctly    ##
    ## - Debug mode now skips the patch process as well                                    ##

    ## - Completely replaced previous regex patterns with one more complex pattern to      ##
    ##   handle hostnames with subdomains, performance increased significantly             ##

    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
