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.
1. 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.

Many internet browser hijackings originate from add-on programs, i.e., browser helper objects (BHO), toolbars, or plug-ins added to browsers to provide them additional features. Other times you might have accidentally accepted a browser hijacker as part of a software bundle (generally freeware or shareware). Popular examples of browser hijackers include CoolWebSearch, Conduit, OneWebSearch, Coupon Server, RocketTab, Delta Search, Searchult.com, and Snap.do.

It really sucks when you can’t fully enjoy the newest version of your favorite OS.
Windows 11 is still relatively fresh and consequently has some annoying little bugs that really ruin our experience. The good news is that you’re not alone and most of them are easy to fix.
Here are 5 commonly reported Windows 11 issues and what you can do to get rid of them.
1. Windows 11 audio problems
One of the absolute most irritating things in the world is struggling with the sound on your computer. Windows 11 users have reported facing the issue of low or no sound. If you’re currently experiencing the same frustration, you can be relieved. Chances are fixing it will only take a few minutes.
The first thing to check would be whether you accidentally muted your device by pressing the mute button on your keyboard. Yes, we know it sounds a lot like the old “have you tried turning it off and on again?” But it’s important to leave no stone unturned, and the most obvious things are usually the ones we easily overlook.
Moreover, if you have several audio output sources, check whether the right one is selected. You can do this via the Action Center or through Settings. If you want to use the same source every time, we also recommend you set it as the default one.
It’s also important to have a good, up-to-date audio driver. More often than not, this will be the true cause of your audio struggles. Make sure to update your driver, and if that doesn’t work out, you can always un- and reinstall it or install a different one.
Lastly, if all attempts remain unsuccessful, run the audio troubleshooter to figure out what’s actually going wrong.
2. Unable to find files
Such a powerful new operating system, yet it can’t seem to do the simplest thing imaginable? The File Explorer not responding on Windows 11 is one of the most frustrating and most common problems with Microsoft’s newest iteration of its awesome OS.
However, 9/10 times it can be fixed by simply restarting your PC. You could also try killing the Windows Explorer process in the Task Manager and then rerunning it.
If these don’t help, check whether there are any pending Windows 11 updates. A single missing update can compromise your PC’s functionality, so always make sure to install them all on time.
Should none of that work, then there are other ways to solve the File Explorer problem. However, then the issue is probably a bit deeper and it’s no longer in the ‘easy fix’ territory.
3. Start menu not working
Just like the File Explorer, the Start menu is a fundamental element of your OS. So, it’s only natural that its malfunction grinds your gears. It may be more customizable than on previous Windows versions, but it doesn’t always work smoothly.
If you’re facing the so-called Start menu critical error, there are a few things this could be caused by. Usually it means you turned off your system while an important update was still being installed, there is a corrupt file on your PC, or Windows forcefully stopped a program.
Whatever the reason, the solution should be pretty simple. Try the basic steps: restarting your File Explorer (like we explained above) and signing out and back into your account. If that doesn’t do anything, you may want to try uninstalling third-party start menu apps (if you have any), since they can interfere with your default programs’ functionality.
Now, those are the easy fixes. If you get nowhere with them, you might need to identify the root cause and search for more complex solutions than that.
4. Snipping tool not working
Our beloved screenshot tool was introduced with Windows 10 and Microsoft decided to keep it. However, you were probably just as disappointed as us when you tried to run it and failed.
Normally, this can be fixed by installing the latest Out-of-band (OOB) update, or even pending updates in general. Even if your system appears to be up-to-date, run the checker just in case.
Another cool thing Windows 11 lets you do is ‘Repair’ and ‘Reset’, which is the easiest way to troubleshoot your Snipping tool. If this fails, you can also try the good old un- and reinstall method. Simply uninstall the tool through the Control Panel and reinstall it from the Microsoft Store.
Furthermore, in the case of an upgrade from Windows 10 to 11, it may be that the old Snipping tool version is interfering with the launch of the new one. If you don’t care that much about the additional options available with the enhanced screenshot tool, you can use the old version instead.
Simply go to your C Drive, find the Windows.old folder, search for the tool and open it from there. Make sure to pin it to your taskbar as well, if you know you’re going to use it often.
5. Can’t install the latest update
The latest Windows 11 version, 22H2, has brought tons of enhancements to our dearest operating system. Unfortunately, a lot of users still haven’t had the opportunity to experience it. A mere update of your OS version should be the one thing that goes smoothly, but sometimes that’s not the case.
Failure to install 22H2 can be caused by a few things. Most commonly, the issue is caused by lack of storage space or corrupted files, but there could be other culprits.
There are a couple of things you could try. For example, it’s crucial that your drivers be up-to-date and some important services be enabled. These are: Windows Modules Installer, Background Intelligent Transfer Service, Cryptographic Service, Windows Update services.
To enable them, search ‘Services’, find the service you need and right-click on it. Open ‘Properties’ and select the startup type ‘Automatic’.
It may also be necessary to unplug all peripherals that aren’t crucial and disable third-party antivirus tools until after the update is finished.
Ultimately, you can run the Windows Update troubleshooter to detect and fix other possible issues.
Summary
Tiny bugs like these are nothing out of the ordinary. That said, we still all hate when they happen.
Hopefully some of our solutions have helped you to a smoother Windows 11 experience. But if you’re still struggling, feel free to reach out to us. We’d be happy to help!

If you encounter a Blue Screen error that points to the Wdf01000.sys file, then this post might be of help. Wdf01000.sys is a file related to the Windows Driver Framework which is the one that manages the system drivers. So if this file ends up being corrupted, the drivers would start to cause trouble in the system which would lead to a Blue Screen of Death error eventually. There are lots of error descriptions that are associated with the Wdf01000.sys file such as:
DRIVER_IRQL_NOT_LESS_OR_EQUAL
System_Thread_Exception_Not_Handled
Page_Fault_In_Nonpaged_Area
System_Service_Exception
Kmode_Exception_Not_Handled
DRIVER_VERIFIER_DETECTED_VIOLATION

Do not close the window if the process takes a while as it will probably take a few minutes to finish.
Option 2 – 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.

Option 3 – Use the Driver Verifier Manager
The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues. And so if you want to fix the Wdf01000.sys Blue Screen error, you need to use the Driver Verifier Manager:
Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
After that, select the option “Create custom settings”.
Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
Next, select the option “Select driver names from a list” option.
Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
Then click on the Finish button.
Open Command Prompt as administrator and execute this command – verifier /querysettings
The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
Open the Command Prompt as admin again and run this command – verifier /reset
The command will reset the Driver Verifier. Once the process is done, restart your PC and check.
Option 4 – Run the 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 to good system files. To run the SFC command, follow the steps given below.

sudo chmod -R 777 /usr/local/flexnetserver
Note: Administrator password may be asked. While typing no characters are shown, just type out the password and hit return key.
Note: To start the license server only with elevated permissions (using sudo command), change permissions to 755 instead of 777.
Create /usr/local/flexnetserver/licenses directory for network license file location
sudo mkdir /usr/local/flexnetserver/licenses
Find the license server Host Name and Host ID.
Generate the Network License File in the Autodesk Account
Once the license file is generated, make sure it has a .lic extension (e.g. adsk_license.lic) and is in a plain text format and place it in /usr/local/flexnetserver/licenses directory
Note: In this article we will refer to adsk_license.lic as network license file name. Feel free to change the actual name of the license file, but make sure to reflect the new name when using the commands below.
Create a debug.log file in the /usr/local/flexnetserver/ directory using the following command:
touch debug.log
To start the Network License Server use the following command:
To configure the license manager use the following steps:
Download Autodesk Network License Manager v. 11.16.2 for Linux from this link

rpm -vhi nlm11.16.2.0_ipv4_ipv6_linux64.rpm
The license server will be installed in /opt/flexnetserver/ directory.
Find the license server Host Name and Host ID
To obtain the license server system hostid run the following command
/opt/flexnetserver/lmutil lmhostid
From the command output note the hostid in quotes, if the system has two active NIC cards, select the first MAC address.
lmutil - Copyright (c) 1989-2018 Flexera. All Rights Reserved.
The FlexNet host ID of this machine is "000c297949e0"
To obtain the license server system hostname run the following command
/opt/flexnetserver/lmutil lmhostid hostname
From the command output note the hostname of the license server.
mutil - Copyright (c) 1989-2018 Flexera. All Rights Reserved.
The FlexNet host ID of this machine is "HOSTNAME=Centos7.localdomain"
Generate your Network License File in Autodesk Account
Once the license file is generated, make sure it has .lic extension (e.g. adsk_license.lic) and place it in /opt/flexnetserver/licenses directory. If the directory doesn't exits, create it with this command: sudo mkdir /opt/flexnetserver/licenses
Note: in this article we will refer by adsk_license.lic your network license file name.
/opt/flexnetserver/lmutil lmstat -a -c /opt/flexnetserver/licenses/adsk_license.lic
To stop your license server service
/opt/flexnetserver/lmutil lmdown -q -force
alternatively you can also run ps command to obtain process ids for lmgrd and adskflex and then kill those processes
ps -aw | grep lmgrd
ps -aw | grep adskflex
kill -9 (provide process ids obtained by previous commands individually)
To start the license server automatically after the system reboot
Open /etc/rc.d/rc.local script as root and enter license server start up command in it.
touch /var/lock/subsys/local
/opt/flexnetserver/lmgrd -c /opt/flexnetserver/licenses/adsk_license.lic -l /opt/flexnetserver/server_log.logNote: To ensure that the script will be executed during boot, run following command as root.
chmod +x /etc/rc.d/rc.local
Make sure that all necessary ports are open:
lmgrd.exe needs ports 27000 to 27009.
adskflex.exe needs port 2080.
Note: Errors may occur if the network license file is corrupt or in the case of a combined network license it has incorrectly combined licenses. To learn more about combining licenses, see Combining License Files for Multiple Autodesk Products. Use the License File Parser to verify that the license contains the appropriate products and FLEXnet feature codes and does not display an error
Verify that TCP ports (2080, 27000-27009) used by Autodesk Network License Manager are not blocked by Firewall.
The FLEXlm® based version uses the following incoming ports:
TCP ports 2080 (for the adskflex vendor daemon)
TCP ports 27000 to 27009 (for the lmgrd master daemon, which uses the first open port in the range)
Note: If these port addresses are restricted by a router or firewall software, users on the remote side of the router will not have access to licenses controlled by the Network License Manager.
Verify that the client computer is configured with the correct license server name or IP.
Windows:
Clear license server information from the system registry.
Type regedit in the Windows Search box and hit Enter key.
As the key is selected, in right panel ADSKFLEX_LICENSE_FILE will be visible.
Right click on the key and delete it.
Specify the license server in ADSKFLEX_LICENSE_FILE system variable
Go to Start > Control Panel > System and Security > System.
Select Advanced system settings.
On the System Properties dialog, click Environment Variables.
Under System Variables, click New.
Enter ADSKFLEX_LICENSE_FILE for the variable name and 2080@SERVER_NAME _OR _IP for the variable value.
Note: the license server information most often is recorded in LICPATH.lic file and can be verified there too. ADSKFLEX_LICENSE_FILE system variable supersedes LICPATH.lic. Thus, setting the system variable is preferable when this error is seen.
If the license server is on a VPN or a remote network set the FLEXLM_TIMEOUT environment variable:
Go to Start > Control Panel > System and Security > System.
Select Advanced system settings.
On the System Properties dialog, click Environment Variables.
Under System Variables, click New.
Enter FLEXLM_TIMEOUT for the variable name and 5000000 for the variable value.
Click OK to save the setting.
Note: if needed the variable value can be increased to 10000000.
Mac/Linux:
Specify the Autodesk Network License server information in $HOME/.flexlmrc file.
Use a text editor to create a flexlmrc.txt file and save it in Plain text format (In TextEdit on Mac: Format - Make Plain Text) on desktop.
The file content should look like this, except with the name or IP address of the license server.
ADSKFLEX_LICENSE_FILE=@SERVER_NAME _OR _IP
If the license server is on the same machine as the Autodesk software, use localhost as the license server name. Thus, the content of flexlmrc file could look like this:
ADSKFLEX_LICENSE_FILE=@localhost
Note: On firewall restricted network or when accessing the license server via VPN, need to include TCP port/s (usually 27000 or 2080) into Autodesk License Server service as follows: ADSKFLEX_LICENSE_FILE=2080@SERVER_NAME _OR _IP
Once flexlmrc file is created move it to user's $HOME folder as follows:
Open a Terminal window
Type open ~ (Mac) or nautilus ~ (Linux) to open $HOME folder
Drag and drop flexlmrc.txt file from Desktop to the home folder.
To make the file a configuration file, rename it to .flexlmrc (please note . [DOT] in front of the file name) by running the following command:
mv flexlmrc.txt .flexlmrc (Mac)
mv flexlmrc .flexlmrc (Linux)
Verify that the license server information registered with the product is correct (versions 2020 and later only)
In versions 2020 and later, the license server information is registered with the AdskLicensing service running locally on the workstation. When changing to a new license server, the old server information may still be registered with AdskLicensing and result in the error above, if this is not appropriately updated.
See the below steps to solve this:
Click the Start menu and type cmd.
Right-click on the Command prompt and choose "Run As Administrator."
In the Command prompt, run the following command, followed by ENTER:
If you suddenly see a system icon or an application icon that has a blue and yellow shield or icon overlay at the corner, this indicates that the application has to run with admin privileges and each time you run these kinds of applications, a UAC or User Account Control prompt will appear to confirm if you really want to run the application. Although this kind of behavior is for security reasons, it can get quite annoying especially if you use the application on a daily basis. To make it convenient for you, this post will walk you through how you can remove the blue and yellow shield icon from an application on your Windows 10 computer.
The User Account Control or UAC setting is the one that ensures no program can run with administrative privileges unless it is allowed by the user. This stops any program that could be potentially harmful to the computer from making any changes which are why keeping this setting to its default state is for the best and making any changes in its setting is not recommended unless it is really needed.
So if you really have to remove the icon overlay in an application, there are several ways you can do that. You can try reinstalling the program and set Compatibility or change the UAC level. For more information, refer to every option given below.
Option 1 – Try to reinstall the application and set Compatibility
As you know, the application icons where you can see the shields are shortcuts mostly and they signify that the User Account Control will appear each time you launch the app. Thus, if you have an app that you use regularly and you’re certain that the app can be trusted, you can try to reinstall the app and set its compatibility by following these steps:
You need to uninstall the app first and then install its latest version. You must not run or open the app after you reinstall it, not until you’ve completed the steps.
Next, you have to right-click on the shortcut icon of the app, and from the menu, select Properties.
Afterward, go to the Compatibility tab and look for the checkbox labeled “Run this program as an administrator” and uncheck it.
Now click on the Apply and OK buttons to save the changes made. This should remove the shield icon from the app.
Option 2 – Try changing the UAC level
Tap the Win + Q to open the search bar and type UAC to see the User Account Control setting.
From the UAC setting, lower the UAC level by selecting the settings that say, “Notify only when apps try to make changes to my computer”.
After selecting that option, you shouldn’t be getting any warning now when you run the app with the shield icon. But keep in mind that this is not a temporary setting which can be risky especially if the app can’t be trusted.
