If you suddenly encounter a Blue Screen error that points out to either the mfewfpk.sys and epfwwfp.sys files, then this post might help. Both of these files are created by third-party software. The mfewfpk.sys file is created by the McAfee security software while the epfwwfp.sys is created by the ESET Antivirus. These files are residual files and sometimes it blocks upgrading Windows 10.

Create Custom Views in Event Viewer
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.

Setting default applications in Windows 11
Setting default applications in Windows 11Same as in previous Windows versions, Windows 11 will also use certain applications as default ones for opening certain file types and file extensions. And yes, same as in previous versions it will come preconfigured for certain file types and associated applications like for example photos for pictures. Of course, users usually have their own favorite applications for certain file types and much more prefer to open them inside the application of their choice instead of the default one. We can change the default application like in previous Windows versions but this time there are two ways and overall more control of this process. Windows 11 has settings for choosing default file type applications and default file extension applications giving you more control of this process.

The opening setting for apps

Whatever you wish to change default application or default extension application you will need to open settings for default application. Follow steps to quickly go into it.
  1. Press ⊞ WINDOWS + I to open settings
  2. Select Apps on left
  3. On the right part select Default Apps
Now you are in settings for choosing default applications

Choosing default application by file type extension

This is considering by Microsoft as a typical way to set default applications inside Windows 11. Once you are inside the settings app there is a box labeled Enter a file type or link type. Inside the search box, type in file extension that you wish to associate the application with like .JPG, .TXT, or other. If the file extension is not associated with any application you will be presented with a Choose a Default button, if however, the file extension is already associated with the app, you will need to click on the app box itself. In any case, a pop-up will appear and ask How do you want to open YOUR FILE EXTENSION files from now on? Choose Application from the list of presented ones and click on OK.

Choosing default file type

Another method is to select the default application by file type selecting application for it. In the settings screen, under the search box, you will have a list of installed applications. Choose the application that you would like to associate a file type with and click on it. On the next details screen scroll down and select the file type that you want to associate with the selected application and click on OK.

Other/third method

There is also the third method for choosing the default application for file type but it includes some surfing on your hard drive and it can be more time-consuming for first-time settings. But it is fairly quick when you need to only use it once on some new file type (for example you have a new application installed and want to switch just one file type extension to that application). Locate the file that you want to associate with the application and right-click on it. Select Open With from the menu and then Choose Another App. Pop up will appear, select the application that you would like to use, and check the box beside Always use this app to open CHOOSEN EXTENSION files followed by clicking on the OK button.

Fixing errors, manually vs automatic

Encountering errors is never a pleasant experience and fixing errors can sometimes take a large amount of time. Also depending on your expertise and knowledge about computers and the operating systems themselves could be determining factor would you try to wrestle with error.

error fixing on computer

We will explore and analyze the advantages of both methods so you can choose and know when to apply one and when to reach for the other.

Advantages of manual method

Full control is the main advantage of manually solving errors, when you go deep dive into manually fixing problematic issues you are one that has control. Complete freedom is also another, sometimes fixing things can be done in several different ways and when you are the man behind the wheel, you are the one that can choose how to approach and what solution to apply in order to solve the issue.

Disadvantages of using manual method

The main disadvantage that some users might encounter is that they will need to know ins and outs of computer and operating systems' workings. Of course, the more complicated errors, the more knowledge it will require in order to apply the proper fix. There is also a risk to break something else if the person that is doing the fixing is not fully competent so this is also something to think about.

Another thing that goes against manual fixing is the time it will require in order to actually fix it, some more complex stuff will probably depend on searching for some external resources like searching for compatible drivers for example, or navigating complex registry keys inside Windows.

Advantages of automatic solutions

If you are a user that has no knowledge about how the operating system works, if you do not know what is a registry or how to properly navigate through the Windows folder then the automated solution is for you. The main advantage of automated systems is that you can easily fix errors without any kind of technical knowledge and usually with just one click of a button.

Saving time is also one of the advantages of fully automated solutions because they will work much faster than manually locating the problem and then fixing it. Also, most of these systems will have in place active monitoring that will check always if your system is in top form and alert you when something is not right.

Disadvantages of one-click solutions

Automated solutions are great, they can solve various issues and errors without any knowledge from the user, but they are not perfect. Like security suites sometimes an automated system can misinterpret something as an error when in fact it is not and fixing it could mean some apps not working anymore, luckily you can choose would you like to apply the suggested solution. So if you are using one do not just click fix without looking at what it is trying to fix and maintain.

Another problem with this is the price it is carrying, manually solving your computer error will cost you your time and knowledge but good automated software will come with a price tag. Some people might not be too happy to pay for this kind of application but at the end of the day, it will still be cheaper than a professional technician. The last thing that you should be aware of is that in order for the app to do its work properly it will need to be active all the time, now for modern computers, this is not the issue but for some older ones with a small amount of memory might lead to some slowing them down. This is a price to be paid in order to have your system always errors free.

Should you use an automated solution at all?

This depends on your knowledge and time available, professional IT technicians will not need this type of solution nor will power users but for most common people this will offer computers free of errors for an affordable price.

Remove CalendarSpark Browser Hijacker

CalendarSpark is a browser extension developed by MindSpark. This extension allows an easy way to print or view calendar templates and make schedulers for a day/week/month/year. This browser extension hijacks your browser home page and search engine, changing them to MyWay.com. While the extension is installed it monitors your browsing activity and collets visited websites, clicked links, and sometimes even personal information, which it later uses to display targeted unwanted ads through your browsing sessions.

While browsing the internet with this extension installed you will see additional sponsored links, ads, and sometimes even pop-up ads on websites that are not supposed to have any of these. Several anti-virus scanners have detected this extension as a Browser Hijacker, and due to its data collecting behavior, it is not recommended to keep it on your computer.

About Browser Hijackers

Browser hijackers (sometimes called hijackware) are a kind of malware that modifies web browser configuration settings without the computer owner’s knowledge or permission. These kinds of hijacks are raising at an alarming rate across the world, and they could be truly nefarious and sometimes harmful too. Browser hijacker malware is created for a number of reasons. These are generally used to force hits to a specific site, manipulating web traffic to generate ad revenue. However, it’s not that harmless. Your online safety is jeopardized and it is also extremely irritating. In a worst-case scenario, your browser could be hijacked to open up your computer system to a host of additional attacks.

Indications of browser hijack

When your browser is hi-jacked, the following could happen: your home page is reset to some unknown webpage; you get redirected to sites you never intended to visit; The default search page of the web browser is changed; unwanted new toolbars are added to your internet browser; you’ll find random pop-ups start showing on a regular basis; your internet browser starts running slowly or exhibits frequent errors; Inability to navigate to certain websites, particularly antivirus as well as other security software sites.

Exactly how browser hijacker finds its way onto your PC

Browser hijackers can enter a PC by some means or other, including via file sharing, downloads, and e-mail as well. They could also be deployed via the installation of an internet browser toolbar, add-on, or extension. A browser hijacker can be installed as a part of freeware, shareware, demoware, and pirated programs. An example of some well-known browser hijacker includes Conduit, Anyprotect, Babylon, DefaultTab, SweetPage, RocketTab, and Delta Search, but the names are regularly changing. Browser hijackers could interrupt the user’s web surfing experience significantly, track the websites visited by users and steal sensitive information, cause problems in connecting to the net, and then finally create stability issues, causing programs and computers to freeze.

Removal

Some kinds of browser hijackers can be quickly removed from the computer by deleting malicious applications or any other recently added freeware. Regrettably, most of the software applications used to hijack an internet browser are intentionally designed to be difficult to remove or detect. Furthermore, manual removals require in-depth system knowledge and therefore can be an extremely difficult job for novice computer users.

What you can do if Virus Stops You From Downloading Antivirus?

Practically all malware is inherently dangerous, but certain types of malware do much more damage to your computer than others. Some malware sits in between your computer and your internet connection and blocks a few or all websites that you would like to check out. It will also block you from the installation of anything on your PC, especially antivirus applications. If you’re reading this article now, you might have perhaps realized that virus infection is the real cause of your blocked net connectivity. So how to proceed when you want to download and install an antivirus application like Safebytes? Although this sort of problem can be tougher to circumvent, there are some steps you can take.

Download the software in Safe Mode with Networking

In Safe Mode, you may change Windows settings, un-install or install some program, and eliminate hard-to-delete viruses and malware. In case the virus is set to load immediately when the PC starts, switching to this mode can prevent it from doing so. To boot into Safe Mode, press “F8” key on the keyboard just before Windows logo screen appears; Or after normal Windows boot up, run MSCONFIG, look over Safe Boot under Boot tab, and then click Apply.
