Follow steps in this guide one after another since they go from most simple ones to complex ones so following is advised in order not to waste a ton of time and resources doing wrong tasks.

1. Check your game page and your DirectX

   The first and most common thing that can cause this type of error is when your installed DirectX is not the same version that the game requires. Check the game store page to see system requirements and write down which DirectX version it requires in order to run. Then press ⊞ WINDOWS + R to bring run dialog and type in it DXDIAG and press ENTER DX diagnostic window will pop up and at the bottom, you can find which DirectX version is installed on your system.

3. Set custom scaling to 100

   Go into Windows settings and set custom Display scaling to a value of 100, sign out, and then sign back in.

On September 18th, 2017, Cisco’s Talos announced that CCleaner, a popular utility with billions of worldwide users, had been compromised by hackers, and was used to unwittingly distribute hidden malware in its installer. Later in the day, Piriform, the publisher of CCleaner, confirmed the problem.

Undetected by all but 1 major antivirus including CCleaner’s own parent company, this occurred for over a month and impacted over 2.7 million users. Users of CCleaner v5.33.6162 and CCleaner Cloud v1.07.3191 for 32-bit Windows are affected. These downloads were live on CCleaner’s official site from August 15th to September 12th, 2017. Anyone who downloaded the program during this time could be affected. The company claims that while the hackers set up the backdoor and many users were impacted, that the perpetrators have been arrested and that the malware never successfully performed its full task and compromised user’s PCs or sent out their data; in the wake of recent security breaches such as Equifax, users are understandably worried. Given the severity of the threat of hacking and data theft, users should take action immediately if they have CCleaner.

Technical Details of CCleaner Malware Injection

First reported by Talos, the malware, which was hidden in the CCleaner installer without the publisher noticing (despite them being owned by Avast, a massive Anti-virus company), modified a core program DLL file to evade detection, and creates several registry keys. Not only were these files not flagged by any major Anti-Virus, but they were also even digitally signed by Piriform via their Symantec certificate, meaning your PC and security program would likely whitelist and trust the malicious installer. The malware gathers personal information on a user’s PC, including IP address and running programs, and sends it to a remote server. In our testing, the program sent data to IP 216.126.225.148.

Restore Your PC (If Possible)

As of the publication of this article, there have been no assurances given that updating or even uninstalling CCleaner will remove the malware is installed. The only action thus far has been shutting down the remote server where user data was being sent has been shut down by authorities. For this reason, it is best to remove the underlying malware separately, as its presence represents a serious security threat. Unfortunately, as this could have been installed as far back as August 15th, 2017, your System Restore points may not go back that far, or even if they do, restoring to such an outdated point may cause unintended problems with other programs you use and potentially lost files and data. Manually backing up files and doing a full format or clean Windows installation would likely be successful in fully removing the malware, but is extremely time-consuming and can be difficult for many PC users. Unfortunately, this makes a PC Restore or format an unattainable option for many.

Update CCleaner to the Latest Version

While CCleaner has told users to update to the latest version of the program. Prior to doing so, we recommend fully uninstall CCleaner, ensuring you check its program files folders and registry keys, manually deleting any remnants, and then re-downloading the latest version from the official site and reinstalling clean.

If you got an error message saying, The INF file you selected does not support this method of installation while trying to install a driver using the “Install” option in the right-click context menu, read on as this post will guide you in fixing the problem. The INF file mentioned in the error message is a text file that’s divided into different types of formatted sections. Each one of the sections is designed for a particular purpose. For instance, one section is designed to copy files or to add entries to the registry. INF files are used to install drivers. However, if something is wrong, you might encounter this error while installing a driver on your Windows 10 computer. To resolve this problem, you can try to download the driver again from the official manufacturer website or check if the driver is compatible with your computer’s operating system architecture or you can also try installing the driver from the Device Manager. For more details, follow the given options below.

Option 1 – Try downloading the driver again from the official website of the manufacturer

Usually, you shouldn’t encounter this kind of issue no matter what installation method you used on your Windows 10 PC. However, there are times when the driver itself is corrupted for some reason which is why you are unable to complete the installation and receive an error message instead.

Option 2 – Try checking if the driver is compatible with the OS architecture

It is possible that you’re getting this error if you have a driver that is compatible with a 32-bit system and you are trying to install it on a 64-bit system and vice versa. Thus, you need to check if the driver you are trying to install is compatible with your operating system if you haven’t done it when you’ve downloaded the driver from the website of the manufacturer. To check the system architecture, in the Start Search, type “msinfo32” in the field and hit Enter to open the System Information window. From there, you should see all the information about your operating system. In addition, you can also search “system information” in the Cortana search box and look for the System Type entry and open it.

Option 3 – Try installing the driver from the Device Manager

If you have the driver files on your PC and you have to update a driver, refer to the steps given below to be guided on how to install the driver from the Device Manager.

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the driver you want to update, and then right-click on each one of them and select the Update Driver from the menu.
• After that, click on the “Browse my computer for driver software” option.
• Next, select the “Let me pick from a list of available drivers on my computer” option and then click the Next button.
• On the next screen, you should see the “Have Disk” option. Click on this option and then click on the Browse button to go to the location of the file. After that, you shouldn’t have any problem installing the INF file.

Option 4 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the “The INF file you selected does not support this method of installation” error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

 Now restart your computer.

“This webpage was blocked by an extension (ERR_BLOCKED_BY_CLIENT)”

This kind of error, as pointed out, could be caused by an extension or plugin on Chrome that is blocking the web page. It is also possible that the version of Chrome is obsolete or that there could be more than 100 bookmarks in the Bookmark Manager. Before you troubleshoot the problem, make sure that you download the latest version of Google Chrome and see if it fixes the error. If it didn’t, then you can try opening a web page in Incognito Mode or disable and remove the extension that’s causing the problem. You could also try to remove any surplus bookmarks.

Option 1 – Try to open the web page in Incognito Mode

The first thing you can do to fix the problem is to try opening the web page in Incognito Mode. When your browser is in this mode, it will work without extensions. This would help in fixing the problem especially if it was caused by some extension or toolbar in your browser. All you have to do is open any web page in Chrome and tap the Ctrl + Shift + N key combination to open a window in Incognito Mode.

Option 2 – Try to disable and get rid of the problematic extension

After you’ve isolated the problem and have determined that an extension is the one that’s causing it, then the next thing you have to do is to disable or get rid of that extension.

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome.

Option 3 – Try removing surplus bookmarks

If your Chrome browser is already supporting more than 100 bookmarks, you might want to consider deleting them as it could also be one of the reasons why you’re getting the ERR_BLOCKED_BY_CLIENT error. To remove these bookmarks, just open the bookmark library by typing this address “chrome://bookmarks/” in the address bar of Chrome and tap Enter and press Shift and then select the surplus bookmarks by using the arrow keys. After that, click Delete to get rid of them.

Option 4 – Try clearing browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BLOCKED_BY_CLIENT. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
• Now select every checkbox that you see and click on the Clear browsing data button.
• Then restart your Chrome browser and check if you can now open any website or not.
