They not only screw up your web browsers, but browser hijackers can also modify the system registry, making your computer susceptible to other malicious programs.

How to know whether the web browser is hijacked?

Here are a few of them: 1. the browser’s homepage is modified 2. you find yourself regularly directed to a different webpage than the one you intended 3. the main web browser settings are modified and undesirable or insecure resources are put into the trusted sites list 4. you are finding new toolbars you haven’t witnessed before 5. you see a lot of pop-up ads on your computer screen 6. your web browser gets sluggish, buggy crashes often 7. Inability to navigate to certain websites, especially antivirus as well as other security software websites.

How browser hijacker infects computers

Browser hijackers attack computers via malicious email attachments, downloaded infected computer files, or by checking out infected sites. They may also originate from any BHO, browser extension, add-on, toolbar, or plug-in with the malicious objectives. Also, certain shareware and freeware can put the hijacker in your computer through the “bundling” technique. A good example of a well-known browser hijacker is the most recent Chinese malicious software known as “Fireball”, which has infected 250 million computers around the world. It acts as a hijacker but can be turned into a fully functioning malware downloader later on.

While browsing the internet, if you suddenly encounter a warning with an error message saying, “Server certificate has been revoked ERR CERT REVOKED” then it indicates that the SSL certificate used by the website has been revoked by its issuer. This kind of problem can only be fixed by the website owner but that does not mean that you can’t do anything about it. In fact, you have the option to bypass this error as well as contact the certificate issuer – all this and more. Just a reminder, if a website that accepts payment, its passwords don’t have SSL or has some certification issue, you should never trust it. For instance, if you are trying to purchase something online and you’re on the payment stage but you encounter the “Server certificate has been revoked ERR CERT REVOKED” error, you must not proceed. To resolve the “Server certificate has been revoked ERR CERT REVOKED” error, here are some things you can do.

Option 1 – Try contacting the Certificate Issuer

If you are the website owner, of course, the best thing you can is to get in touch with the Certificate Issuer in order to resolve the problem.

Option 2 – Try fixing the Date and Time

You have to check your computer’s Date and Time. There are cases when this simple setting causes a connection problem. So if your computer Date and Time is set to date or time that this after the certificate expiration date, then you have to make sure that you set it to automatically configure time. To do so, just open Settings > Time and Language. From there, turn on the toggle for “Set time automatically” and “Set time zone automatically” options. After that, check if it fixes the error, if not, you need to check if the manual selection is correctly set or not.

As pointed out earlier, you have the option to bypass the Certificate Revocation check. All you have to do is follow the steps below.

• In the search box of your browser, type “internet options” and open it once it appears.
• After that, go to the Advanced tab and navigate to the Security subheading.
• Next, uncheck the “Check for publisher’s certificate revocation” option as well as the “Check for server certificate revocation” option.
• Now restart your computer. Upon the next startup, try opening the website again. This time, your browser will stop checking it for certificate issues. However, it’s not safe to leave those options unchecked so make sure that once the website’s SSL certificate is fixed or once you no longer have to visit that website, you recheck those options.

Error 0xA00F4244 or 0x200F4244 is when Windows can not detect the WEB camera in your system and it is usually accompanied by the message: We can’t find or start your camera. There could be several reasons for this error and in this guide, we will cover all of them in order to help you to get back on track and start using your WEB camera which is perhaps now more required than ever in this world we live in.

1. Check privacy settings

   With the latest Microsoft Windows updates come the latest issues and it is not strange that privacy settings can become reset or changed when an update is applied. This is a quick fix to this issue and can be the sole reason why you get this error, go to Windows settings, then to privacy and check to see if the WEB camera is turned OFF, if this is the case turn it back ON and make sure that option Allow apps to access your camera is also set to ON.

2. Check if the camera is enabled

   Sometimes it is by mistake, sometimes by an update but the web camera could be disabled in the device manager of Windows. Right-click on the Windows Start button and click on device manager to open it up, find and expand the cameras category. Right-click on your camera, if it is disabled, you will have the option to enable the camera, if it is enabled and Windows is detecting that it is working fine you will have the option to disable it.

3. Check antivirus settings

   Antivirus and firewall applications are in today's world and life-essential piece of software but they can sometimes create more harm than good, from stopping windows updates to killing important services of applications and preventing internet access being just some examples of their paranoid behavior. Try disabling or turning your protection software OFF and see if your WEB camera will miraculously come back to life. If this is the case, somewhere in the settings of software there is an option that controls this aspect, try to locate it and set it in that way so you are able to use your camera.

4. Reinstall camera driver

   If the previous three solutions failed to produce a satisfactory solution then reinstalling the camera driver might fix the problem. Go to your manufacturer's camera website and download the latest driver for your camera. Go to the device manager and uninstall the driver for the camera, then apply the latest driver and reboot the system.

5. Check connections and cable

   Sometimes an issue is not due to software nature, sometimes it is hardware. Try checking connections and plug the camera in another USB port, twist and turn the cable a little to see is issue cable-related.

6. Check to see if the application supports your camera

   If Windows has detected the camera and is not reporting any issues with it check your application to see if it can detect your camera and that it supports it fully. Sometimes newer applications tend to support only newer camera models. Try to use the camera in other software as well to see if the problem is with the application you are using.

7. Try camera on another computer

   If everything else fails, try the camera on another computer to see if it will work there. If the camera is not working there as well it is probably malfunctioned and broken for good. If it does work there, try to find out what is different in that computer in comparison to yours, maybe it is some service running in the background, certain application configuration, Windows version itself, USB port version, or something else.

If you are frequently experiencing slow loading of folders in your Windows 10 computer, Downloads folder for instance, then you’ve come to the right place as this post will help you resolve such issue. Slow loading of folders is a common problem faced by many users even when they are using the latest hardware like SSDs. So if you experience the same thing, be it with the Downloads folder or other folders on your computer, there is a way to resolve that issue and make the folder load faster. Slow-loading means when you attempt to open the folder, it takes a couple of seconds before it displays its contents. In such cases, you’ll see a green loading address bar that says “Working on it” which can get quite annoying especially if you are in a hurry. And if you notice that this only happens in the Downloads folder, there certainly is something wrong. This kind of problem can occur on SSDs and normal hard drives. The main reason behind the occurrence of this problem is that the folder may have been optimized for viewing photos or other media formats which is why it takes quite longer than usual to load all the files and their thumbnails. However, since the Downloads folder usually contains all kinds of files like documents, zip files, audio/video files, etc. there is no need to optimize this folder for media files only because doing so is only going to make the Windows File Explorer slow in loading the folder’s contents and thumbnails which does not exist for many files.

Option 1 – Configure the Downloads folder

• Right-click on the Downloads folder or the folder you’re having trouble opening.
• Then click on Properties and go to the Customize tab.
• After that, click on the “Optimize this folder for” option in the drop-down menu.
• Next, select General items from the drop-down which might have been set by default to Pictures or Video.
• You also have the option to apply this template to all the subfolders, that is if your folder has any subfolders.
• Now apply the settings and restart Windows Explorer.

Note: Once you’ve completed the steps above, it should now make the folder content display a lot faster than before. Now try to open the Downloads folder which would not take much time as you will see the changes right away.

Option 2 – Run CHKDSK to check your disk for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. This error check utility can help with several issues in the system including File System Error -2147219196.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

chkdsk /r /f

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.
• Once your computer has restarted, try accessing the file and check if the error persists.

The latest update from Panos Panay on Twitter is including New and redesigned Snipping tool inside Windows 11. From the shared video, we can see that it includes modern Windows 11 UI redesign and it looks and feels like a part of Windows 11. More things that can be seen from the shared video is that it looks like the new snipping tool is a merged version of the old with snip & sketch. It is good to see that it is still possible to capture screen with easier way natively inside Windows 11 but some more functionality would be more welcome I guess. Users were asking for added functions for a long time like adding simple text for example but from shared video, no new features were presented so for some users 3^rd party solutions will still be the way to go. The new and redesigned Snipping tool will roll out with the next update and we will see then about all new features inside it firsthand. Until then, take care.
