The Event Viewer in the Windows operating system is used to troubleshoot any computer issues. It is one of the most useful tools that keep logs of both security and system events. It also monitors for both software and hardware problems in the computer. This tool is the only one with amazing features that maintain logs about everything that’s going on in the computer system. It keeps track of all the information to the point where going over them will take a lot of time.
Luckily, the Event Viewer tool now allows users to create custom views where you can set the filters and sort the data recorded to limit the information details to only what you’re interested in seeing. For instance, if you want to troubleshoot with one hard drive, you can just create a special custom view to display only the hard drive warnings in the security logs. This will save you hassle and time.
Take note that the logs in the Event Viewer are divided into two main categories namely the Window logs and the Application and Services logs. You can just set the filter to the logs by their event id, specific date, and many other events when you have to troubleshoot some problem in your computer. So if you are trying to troubleshoot a problem in your Windows 10 computer and you’re checking the Event Viewer, read on as this post will guide you in creating custom event views in the Event Viewer. To get started, refer to the instructions given below.
Step 1: Go to the Start menu and in the search box, type “event viewer” and then click on Event Viewer from the search results to open it.
Step 2: After opening Event Viewer, click on Custom Views located in the left pane of the window.
Step 3: Next, click on the Administrative events under the Custom View to create special log views.
Step 4: Then on the right side of the window, click on Create Custom View to open the Create Custom View window.
Step 5: There is a logged drop-down list under Filter. From there, you have the option to choose an appropriate predefined time or use a custom time range for your Custom log views.
Step 6: After that, select an appropriate event level for your custom view. You have fine entry-level options to choose from such as critical event level, error, warning, information and verbose.
Critical – select this if you want to see the events that require your immediate attention in the custom view.
Error – select this if you want your Event Viewer to display the events that are less critical but hints at the problems.
Warning – select this event-level if you want to see the event with the potential problem but may not bound to happen.
Verbose – select this if you want to see detailed information about all the events.
Step 7: After you’ve selected the event level, you now have to select how you want the events to be filtered. They can either be filtered By the log or By the source.
By the log – you can select two options called Windows log and, Application and Service logs. The Windows logs allow you to filter the logs created during events like setup, security, applications, and system events. While the Application and Service logs filter the log created by the installed applications in your system.
By the source – select this if you want your Custom View to search for information in event sources. It allows you to view events in detail for various applications and devices.
Note: You have the option to further customize the event logs with more filters like Event IDs, task category, keywords, User, and Computer. Using these additional filters, you can choose to filter the events in the special views by specifying event id numbers in the Event IDs, entering predefined Windows words in the Keyword, specify the user accounts in the User field, as well as choose the system from the server to maintain logs in the Computer field.
Step 8: Once you’re done customizing the log filter, click on OK to apply the changes made.
Step 9: After that, a Save Filter should be displayed in the Custom View window. Just enter the Custom View name and select the Event Viewer folder where you want to save the Custom view. The folder name should be Custom View by default. And if you want, you can also create your own folder if you want your custom views to be visible to all the system users.
Step 10: Next, check all the Users box located in the lower corner of the window and then click the OK button after you’re done.
You should now see the customized filter you just created on the left side of the window. Just click on it to check your filtered events in the center of the Event Viewer window. And for you to save the custom view logs, simply right-click on the Custom views you created and then click on Save All Events in the Custom View As from the drop-down menu. Then put a name on the file and select the appropriate location where you want to save the logs and click on the Save button. Note that the log file is saved with the “.EVTX” file extension and when you double click on it, it will open the file in the Event Viewer.
BitCoinMiner is a Malware created with the intent to force computer systems to generate crypto-currency, namely Bitcoin. This is done without the consent and knowledge of a computer/system holder. This unwanted file bears no digital signature or publisher since the creators of such a heinous invention do not wish to be known.
Technical details about BitCoinMiner Malware include:
After installation of the BitCoinMiner Malware, there were no visible signs of an infection or program files installed. However, based on research, BitcoinMiner Malware utilizes the CPU’s resources (est. to be about 50%). Computer users have reported that they recognized an unknown process utilizing the majority of their processing space.
the bitcoin miner is used by the creators to penetrate a user’s system, in effect coercing each infected system to mine Bitcoins covertly. After years of mining, a user might discern that their computer is moving slouchy and may even encounter various forms of BSODs. After Bitcoins have been mined in the infiltrated system, the cyber currency is then returned/ sent to the creator of the malware. This venture is a sly and deceptive way to earn Bitcoins since the currency is gaining much popularity.
Further Information on BitCoinMiner
BitCoinMiner works covertly. There are no obvious traces of this program running on a computer system. However, once a computer system is infiltrated, the computer user will realize that their CPU resources are strangely being used up, even while the computer idles.
Another expression of BitCoinMiner is the addition of cookies of various sorts to a computer system. These include:
Tracking cookies
Advert (Adware) cookies
Casale Media (Spyware) cookies
Atwola (Spyware) cookies
Adtech (Spyware) cookies
Once BitCoinMiner is present on a computer system, it can potentially slow it down and also create back doors as a means to install other unwanted and harmful programs.

If you suddenly encountered the PDC WATCHDOG TIMEOUT BSOD Blue Screen stop error with a bug check value of 0x0000014F, then it’s probably due to a system component that has failed to respond with the allocated period which prevents the system from exiting connected standby.
This kind of Blue Screen error could be caused by both hardware and software components. To fix this Stop error, here are some possible fixes you can try that might help but before you proceed, make sure that you create a System Restore point first and boot your computer into Safe Mode with Networking.
Option 1 – Try to rollback, update or disable drivers
The next thing you can do to fix the PDC_WATCHDOG_TIMEOUT Stop error is to roll back, or update, or disable device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
Open the Devices Manager from the Win X Menu.
After opening the Device Manager, look for the device driver named “IDE ATA/ATAPI controllers” and expand it.
Then look for the SATA AHCI Controller entry and right-click on it. If you haven’t updated this driver in a while, select the “Update Driver” option. On the other hand, if you’ve just updated this driver, then select the Uninstall Device option.
Next, follow the screen option to update or uninstall it.
Finally, restart your computer. It will just reinstall the device drivers automatically if you have chosen to uninstall them.
Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.
Option 2 – Try to disconnect or disable newly installed hardware
In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the PDC_WATCHDOG_TIMEOUT Blue Screen error.
Option 3 – Try running the Memory Diagnostic Tool
The Memory Diagnostic tool in windows can help resolve the PDC_WATCHDOG_TIMEOUT Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:
Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.

Check for problems the next time I start my computer
Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.
Option 4 – Try to update the BIOS
Updating the BIOS can help you fix the PDC_WATCHDOG_TIMEOUT BSOD error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.
Tap the Win + R keys to open the Run dialog box.
Next, type “msinfo32” in the field and press Enter to open System Information.
From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
After that, you should see the developer and version of the BIOS installed on your PC.
Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
Now double click on the downloaded file and install the new BIOS version on your computer.
Now restart your computer to apply the changes made.
Option 5 – Try running the Blue Screen Troubleshooter
The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PDC_WATCHDOG_TIMEOUT. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites.
If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:
“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”
And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.
Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs
Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.
Option 2 – Try to disable security.enterprise_roots.enabled
The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.
Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
After that, if an info message appears, confirm it.
Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.
As you know, the Windows Update process takes compatibility seriously. The Windows Updates need to be compatible with the hardware as well as all the installed applications in the computer else the Windows Updates will only get stuck in the process. Two of the Windows 10 errors that shows up during this case is the error 0xC1900208, 0x4000C.
These error codes are caused by incompatible applications which means that there might be an incompatible app installed in your computer that’s blocking the upgrade process and prevents it from finishing. That’s why you need to make sure that all the applications on your computer are updated to their latest versions and then check the compatibility. So if there are any incompatible apps, be sure to uninstall them and then try doing the upgrade once again. Take note that these error codes are just among many compatibility issues that the Windows Update throws up.
Since the error is caused by a compatibility issue, you have three options – first, you can update the incompatible application to the latest version, second, uninstall the application or trick Windows and make it seem like it’s compatible.
Option 1 – Try updating the application or software
As mentioned, you can try updating the concerned application or software to its latest version to resolve the compatibility issue and in turn, fix the errors 0xC1900208 – 0x4000C. Note that depending on where you had installed the application, your steps will change. So if you have it installed directly from the website, refer to these steps:
Look for the built-in option to check the updates since the most application has this option.
You also have the option to go to the website of the application and check if there is a new version available. If there is, download and update the app.
On the other hand, if you have downloaded the app from the Microsoft Store, here’s what you have to do:
Open the Store and click on the three dots located at the top-right of the window.
Next, click the Download and Updates option.
From there, check if there is an update available for the store. If there is, update it.
Option 2 – Try to uninstall the application or software
If updating the app or software to its latest version didn’t help and you’re still getting the error 0xC1900208 – 0x4000C every time you attempt to install the Windows Updates, you may have to uninstall it. You will need to use the usual Program and Features to uninstall it if you have downloaded it from the website.
In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
From there, look for the concerned program and select it and then uninstall it.
Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.
Option 3 – Try bypassing the Upgrade Advisor
There are times when a software developer fails to pass the compatibility test for their apps. It could be that they work on Windows 10 upgraded version but just didn’t pass the compatibility check. So if you are pretty certain that the app really works on Windows 10, you can just bypass the Upgrade Advisor.

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.
Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.
Bad router placement
Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.
So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?
Fish Tanks
Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.
Bookshelves
Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.
Mirrors
The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.
TV
Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.
Things that influence signals in homes
Any kind of metal decoration
Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.
Kitchen appliances and Home utilities
Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.
Home gyms
This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.
Things blocking your Wi-Fi that you have no easy control over
Walls
Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.
Floors and ceiling
This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.
Heating systems
If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.
