Different types of computer viruses

Computer viruses are malicious applications that have the ability to self replicate and spread over the system and various devices, just like viruses in organisms. We all know that computer viruses are bad and that you should avoid them however you can. So in this spirit, we are taking a deeper dive into what kind of viruses exist and how they function.

viruses types1. File-infecting Virus

A virus that attached itself to an executable program. It is also called a parasitic virus which typically infects files with .exe or .com extensions. Some file infectors can overwrite host files and others can damage your hard drive’s formatting.

2. Macro Virus

This type of virus is commonly found in programs such as Microsoft Word or Excel. These viruses are usually stored as part of a document and can spread when the files are transmitted to other computers, often through email attachments.

3. Browser Hijacker

This virus targets and alters your browser setting. It is often called a browser redirect virus because it redirects your browser to other malicious websites that you don’t have any intention of visiting. This virus can pose other threats such as changing the default home page of your browser.

4. Web Scripting Virus

A very sneaky virus that targets popular websites. What this virus does is overwrite code on a website and insert links that can install malicious software on your device. Web scripting viruses can steal your cookies and use the information to post on your behalf on the infected website.

5. Boot Sector Virus

These viruses are once common back when computers are booted from floppy disks. Today, these viruses are found distributed in forms of physical media such as external hard drives or USB. If the computer is infected with a boot sector virus, it automatically loads into the memory enabling control of your computer.

6. Polymorphic Virus

This virus has the capability to evade anti-virus programs since it can change codes every time an infected file is performed.

7. Resident Virus

A resident virus stores itself on your computer’s memory which allows it to infect files on your computer. This virus can interfere with your operating system leading to file and program corruption.

8. Multipartite Virus

A type of virus that is very infectious and can easily spread on your computer system. It can infect multiple parts of a system including memory, files, and boot sector which makes it difficult to contain.

Windows Dynamic Lock is missing or not working
If you are familiar with the Dynamic Lock feature in Windows 10, then it has probably made it easier for you to lock your computer the instant you move away from it. This interesting feature does not need any special software like IR Cameras to use this feature as long as your Windows 10 computer supports Bluetooth which it most likely does. However there are times when the Dynamic lock feature is either missing or not working. When that happens, here are some suggestions that could help you. But before anything else, you need to create a System Restore point first since you will be modifying some critical system settings as well as registry files. After you’ve created a System Restore point, refer to the following options below to fix the issue with Dynamic Lock.

Option 1 – Try using the Settings app

  • Tap the Win + I keys to open the Settings app and then navigate to Accounts > Sing-in options.
  • After that, scroll down until you see the Dynamic Lock section.
  • Next, make sure that the checkbox for “Allow Windows to automatically lock your device when you are away” is checked.
  • Now that you’re all set, exit the Settings app.
Note: If for some reason the above-given solution didn’t work, you can try the next options below.

Option 2 – Try to pair your Bluetooth Device

If you get a message saying, “Allow Windows to automatically lock your device when you are away” in the Notifications Center or in the Settings app, then you need to pair your Bluetooth device. To do so, follow the steps below.
  • Go to Settings > Devices > Bluetooth & other devices.
  • From there, make sure that Bluetooth is turned On and then pair your Bluetooth device.
  • And if you open the Windows Defender Security Center, you will see the following message as well.
  • Simply click on the Add Bluetooth device button and it will open the Bluetooth settings where you can also pair the device.

Option 3 – Try to reinstall or update the Bluetooth driver

The issue might have something to do with the Bluetooth drivers. It could be that it is outdated and needs to be updated or that you recently updated it and since then you have trouble removing the Bluetooth device and so to fix the issue, you can update, roll back or uninstall the Bluetooth drivers. How? Follow the steps below.
  • Tap the Win + X keys to open the Device Manager.
  • Next, look for the Bluetooth device and right-click on it.
  • Select the option “Update driver”.
  • After that, a new popup window will appear. In there, select the option, “Search automatically for updated driver software”.
Note: Checking the update may take a few minutes so you’ll have to wait until it finishes. If it is able to find an update, you must install it. And if you want to reinstall the Bluetooth driver, just select the “Uninstall driver” option and follow the next on-screen instructions that follow.

Option 4 – Try to use the Registry Editor

  • Tap the Win + R keys to open the Run dialog box and then type “Regedit” in the field and hit Enter to open the Registry Editor.
  • If a User Account Control or UAC prompt appears, just click on Yes to proceed.
  • After that, navigate to the following registry key:
HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWinlogon
  • Next, look for a DWORD named “EnableGoodbye” located on the right-side panel and then make sure that its value is set to 1 which means that it is enabled while 0 indicates disabled.
  • Now close the Registry Editor and restart your computer to apply the changes made successfully.

Option 5 – Try checking the Group Policy setting

If your Windows 10 version has the Group Policy Editor, you can use it to fix the Dynamic Lock issue as well. Simply follow the steps below to use it.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
  • Next, navigate to the following path:
Computer ConfigurationAdministrative TemplatesWindows ComponentsWindows Hello for Business
  • After that, look for an entry named “Configure dynamic lock factors” and double click on it to open a new window.
  • Once you enable this Group Policy setting, the signal rules will be evaluated to detect the absence of a user and will lock the device automatically. On the other hand, if you disable or don’t configure this setting, you can continue locking your computer with existing locking options. Take note that it may be Not configured or Enabled but shouldn’t be set to Disabled.
  • Now select the radio button for Enabled and set the Signal rules then click OK.
  • Then exit the Group Policy Editor and restart your computer.

Media Player can't detect the length of file
Even with the new Groove Music in Windows 10, a lot of users still prefer to use the old Windows Media Player. This isn’t surprising since Windows Media Player still remains to be one of the best players you can find. However, that does not mean that it is without flaws as it could still encounter some issues from time to time. One of the issues you might encounter when using the Windows Media Player is when you try to burn DVDs or CDs but end up failing due to an error that pops up that says, Windows Media Player cannot detect the length of the file. At the time of writing, it isn’t clear yet what the real cause of the error is. However, there are several fixes that are provided in this post for you to check out so you can resolve the problem. You can try to get rid of any unsupported files from the burning list or you could also try running the Windows Media Player troubleshooters. Aside from that, you could also try to drag and drop music or change the burning speed. For more details, refer to the following options.

Option 1 – Get rid of the unsupported files from the burning list

You must get rid of the unsupported files from the list of files to burn. This list can be found on the right-hand side of the Windows Media Player. One of the indications that a file is causing problems is when there is a white cross in a red circle next to the file. You can simply click on that icon to remove the file from the burning list. Once you’ve gotten rid of all the unsupported files, try to burn your files to the CD or disk once more.

Option 2 – Try running the Windows Media Player troubleshooters

The next thing you can do to fix the error is to run the built-in troubleshooters for the Windows Media Player. Windows 10 actually comes pre-packed with three troubleshooters designed for Windows Media Player. They can help in fixing the “Windows Media Player cannot detect the length of the file” error. To run these troubleshooters, simply tap the Win + R keys to open the Run dialog box and type “msdt.exe -id WindowsMediaPlayerConfigurationDiagnostic” for the Windows Media Player Settings troubleshooter or type “msdt.exe -id WindowsMediaPlayerLibraryDiagnostic” for the Windows Media Player Library troubleshooter, or type “msdt.exe -id WindowsMediaPlayerDVDDiagnostic” for the Windows Media Player DVD troubleshooter.

Option 3 – Try to drag and drop music

Another thing you can check out is to drag and drop all the tracks into the Windows Media Player before you burn them. All you have to do is open the folder where the tracks are located and highlight all of them and then drag them to the Windows Media Player. It should now be able to detect the length of each one of the tracks without any errors.

Option 4 – Try to change the burning speed

Since the burning speed is set to fastest by default, you can try to change the burning speed to resolve the problem. Just open the Options window and then go to the Burn tab. From there, select either Medium or Slow burning speed and save the changes made. Now try to burn your files to the CD or disk once again.

Unhandled Exception occurred in Application
If you encountered an error message that says, “Unhandled exception has occurred in your application”, when you start your Windows 10 computer, read on as this post will guide you on how you can fix it. This kind of error usually appears in a Microsoft .NET Framework window and it mostly pops up as soon as you turn on your computer. Here’s the complete context of the error message:
“Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.”
When this error occurs, your computer may freeze or display other suspicious behavior at times. Either way, there are several options you can check out in this post to resolve this issue, so read on. This kind of error could be caused by several factors. It could be due to your antivirus program or other third-party programs installed on your computer. It is also possible that the installation of the Microsoft .NET framework id corrupted or some of its installation files are corrupted. Thus, to fix the error, there are a few suggestions you need to follow such as:

Option 1 – Try to temporarily disable your anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed on your computer. Thus, disabling them or any security software installed in your computer is always a good idea you can try when you’re not able to access the shared drive in your computer. There are times when you encounter problems like the “Unhandled exception has occurred in your application” error due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program in the meantime and check if it fixes the error or not.

Option 2 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
  • Once your computer has restarted, check if the error is now gone. If it is, then the culprit is some third-party program. Thus, you have to enable the third-party programs one by one to find out which one of them is causing the the “Unhandled exception has occurred in your application” error.

Option 3 – Try to run a System File Checker scan

System File Checker or 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 that might be the cause why you’re getting the “Unhandled exception has occurred in your application” error. To run the SFC command, follow the steps given below.
  • Type “cmd” in the Start search and then right-click on the appropriate search result.
  • Next, select “Run as administrator” to open Command Prompt with admin privileges.
  • 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 and see if the problem is fixed or not.

Option 4 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual check especially if you are getting this issue of abnormal program termination.
  • Install some qualified drivers – A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.
  • Download and install or Update DirectX – As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.
  • Install the Microsoft DirectX End-user runtime – The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.
  • Update or install the .NET framework – The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.

How to Remove AtoZ Manuals from Windows

AtoZManuals is a Browser Extension developed by MindSpark Inc. This extension offers users an easy way to search Customer Manuals for Products. This extension may seem handy at first, however, this extension hijacks your browser home page, and changes your default search engine to MyWay.

While browsing the internet with this extension you will see additional ads, sponsored links, and pop-up ads in your browser. Additionally, this extension monitors your browser activity, including search words, visited links, shopping information, and sometimes even personal information, which is later used to display better-targeted ads.

Multiple anti-virus scanners have marked this extension as a Browser Hijacker, and due to its rogue behavior, it is not recommended to keep it on your computer.

About Browser Hijackers

Browser hijacking means a malicious program code has control over and altered the settings of your browser, without your permission. They’re made to interfere with web browser functions for various reasons. Often, it’ll drive users to predetermined websites that are trying to boost their ad earnings. Although it may seem naive, these tools were created by vicious people who always look to take advantage of you, so that hackers could earn money from your naivety and distraction. When the program attacks your laptop or computer, it begins to mess things up a whole lot that slows your system down to a crawl. In the worst-case scenario, you may be forced to tackle serious malware threats as well.

How one can recognize a browser hijack

There are various signs that indicate the internet browser has been hijacked: your homepage is reset to some unfamiliar website; you observe new unwanted favorites or bookmarks added, typically directed to ad-filled or porn sites; default search engine is changed; you see many toolbars on the browser; your internet browser displays endless pop-up windows; your browser has become unstable or starts running sluggishly; you’re prohibited access to specific web pages, for example, the site of an antivirus software developer like SafeBytes.

How it infects your PC

A browser hijacker could be installed on your PC when you check out an infected website, click on an email attachment, or download something from a file-sharing website. They are generally included with toolbars, add-ons, BHO, plug-ins, or browser extensions. A browser hijacker could also be installed as a part of freeware, shareware, demoware, and fake programs. Examples of popular browser hijackers are Fireball, CoolWebSearch. GoSave, Ask Toolbar, RocketTab, and Babylon Toolbar.

Getting rid of browser hijackers

Some kinds of browser hijackers can be removed from the computer by deleting malicious software or any other recently added freeware. However, many hijackers are much more difficult to discover or remove since they could get themselves connected with some important computer files that enable it to operate as a necessary operating-system process. Furthermore, manual removals demand in-depth system knowledge and thus could be a very difficult task for novice computer users.

Firefox contains built-in Malware and Phishing Protection to keep you secure online.

Install and run antivirus from your USB drive

Removing Default Taskbar Buttons in Windows 11
Windows 11 taskbarI do not know about you, but I prefer to set my Windows to be more to my liking and not how Microsoft thinks it should be. Let’s face it, not all users feel comfortable whit Microsoft settings and idea how things should be. One of the things I particularly did not like even in Windows 10 is icons that come by default on my taskbar, now so far, well until the latest Windows 11 update you could remove default taskbar icons the same way as in Windows 10, just right-click on them and unpin, sadly with latest update build on Windows 11 this option has been removed. In order to remove default icons from the taskbar, one must go now to Windows 11 settings and choose from there which one you would like to be placed on it. Of course, this is nothing game-breaking but it still feels strange why the standard option has been removed, it just makes no sense but lately not many things that come from Microsoft do.

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:

  • PAGE FAULT IN A NONPAGED AREA
  • IRQL NOT LESS OR EQUAL
  • SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)
In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the 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, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties. On the other hand, you can also look for sub-entries under Sound, video, and game controllers like the C-Media USB Audio Class
  • After that, switch to the Driver tab and click on the Uninstall Device button.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. Which is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.
  • Boot your Windows 10 PC in Safe Mode.
  • Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
  • From there, look for the file named sys and rename it to CMUDA.old.
Note: As you can see, the file’s extension has changed from .sys to .old.
  • Now restart your computer and check if the CMUDA.sys Blue Screen error is now fixed.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:
  • Tap the Win + I keys to open the Settings panel.
  • Then go to Update & Security > Troubleshoot.
  • After that, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.
On the other hand, you can also try running the online Windows 10 Blue Screen troubleshooter from Microsoft. It is a wizard that could help you fix any Stop errors related to the CMUDA.sys file and will offer you helpful links as you use it.

Option 4 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.
  • Open the Command Prompt with admin privileges.
  • Then type in the following commands and make sure to hit Enter right after you type each one of them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • exe /Online /Cleanup-image /Restorehealth
  • Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run System Restore

Running System Restore might also help in fixing Blue Screen errors related to the CMUDA.sys file.

Fixing Error 0xC1900208, 0x4000C in Windows
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.
