How to Find Virus On Windows

 

How to Check if a Process Is a Virus or Not

You might be wondering if your computer has a virus because you’ve seen a strange process in the Windows Task Manager, which you can open by pressing Ctrl+Shift+Esc or by right-clicking the Windows taskbar and selecting “Task Manager.”

It’s normal to see  a few processes here — click “More Details” if you see a smaller list. Many of these processes have strange, confusing names. That’s normal. Windows includes quite a few background processes, your PC manufacturer added some, and applications you install often add them.

Badly behaved malware will often use a large amount of CPU, memory, or disk resources and may stand out here. If you’re curious about whether a specific program is malicious, right-click it in the Task Manager and select “Search Online” to find more information.

If information about malware appears when you search the process, that’s a sign you likely have malware. However, don’t assume that your computer is virus-free just because a process looks legitimate. A process could lie and say it’s “Google Chrome” or “chrome.exe,” but it may just be malware impersonating Google Chrome that’s located in a different folder on your system. If you’re concerned you might have malware, we recommend performing an anti-malware scan.

How to Scan Your Computer for Viruses

By default, Windows 11 is always scanning your PC for malware with the integrated Windows Security application, also known as Microsoft Defender. You can, however, perform manual scans.

On Windows 10 or 11, open your Start menu, type “Security,” and click the “Windows Security” shortcut to open it. You can also head to Settings > Update & Security > Windows Security > Open Windows Security on Windows 10, or Settings > Privacy and Security > Windows Security > Open Windows  on Windows 11.

To perform an anti-malware scan, click “Virus & threat protection.”

Click “Quick Scan” to scan your system for malware. Microsoft Defender will perform a scan and give you the results. If any malware is found, it will offer to remove it from your PC automatically.

If you want a second opinion — always a good idea if you’re concerned you might have malware, and your primary antivirus doesn’t find anything — you can perform a scan with a different security application, too.

We like and recommend Malwarebytes, which pairs well with Windows Security to provide an extra layer of protection for your PC. The free version of Malwarebytes will let you perform manual scans to check for viruses and other malware on your PC. The paid version adds real-time protection—but, if you’re just looking to test a computer for malware, the free version will work perfectly.

3. Disable/Enable USB ports by uninstalling USB Mass Storage Drivers

A system can be protected from malicious users on a high scale like in school, office, etc., by uninstalling USB Mass Storage Drivers. You can just uninstall these drivers and when anyone would try to plug in the USB drive then Windows will prompt him/her to install the USB drivers. Later on, you can install the drivers back to make the things work (USB devices detected) again.

4. How Do I Enable USB Ports in BIOS

Some vendors provide an option in BIOS/UEFI to enable or disable the USB ports on the system. In other cases, you may also have accidentally disabled usb ports. Boot into the BIOS.UEFL to check if such an option or feature is available on your system. You can check the user manual of your PC to see if the feature to enable or disable the USB ports is available in the BIOS.

5. Disallow Users to Connecting USB

Use one or more of the following methods to block users from connecting to USB storage devices, as appropriate for your case.

If there is no USB storage device already installed on your computer

If a USB storage device isn't already installed on the computer, assign Deny permissions to the following files to the user or group and the local SYSTEM account :

• %SystemRoot%\Inf\Usbstor.pnf
• %SystemRoot%\Inf\Usbstor.inf

Users can not install a USB storage device to the computer when you do this. To assign Deny permissions for the files Usbstor.pnf and Usbstor.inf to an individual or group, follow these steps:

1. Start Windows Explorer and find the %SystemRoot%\Inf folder.
2. Right-click on the file in Usbstor.pnf, then press Properties.
3. Click on the Security tab.
4. Add the user or group you want to set Deny permissions to in the Group or UserNames list.
5. Click to pick the Reject checkbox next to Complete Access in the UserName or GroupName Permissions column.

Note In the Deny list, also add the System account.

6. Select the SYSTEM account in the list of groups or Usernames.
7. Click on the Deny check box next to Full Control in the UserName or GroupName Permissions list, and then click OK.
8. Right-click file Usbstor.inf, then click on Properties.
9. Click on the Security tab.
10. Add the user or group you want to set Deny permissions to in the Group or User Names list.
11. Click to pick the Reject checkbox next to Full Control in the UserName or GroupName Permissions list.
12. Select the SYSTEM account in the list of Group or UserNames.
13. Click on the Deny check box next to Full Control in the UserName or GroupName Permissions list, and then click OK.

6.  Disconnect USB

It is impossible to disconnect all the USB ports from the motherboard; all you can do is to disconnect those exist on the top and front of the computer by plugging out the cable from the USB header. Disconnecting these ports prevents people from miscuing them. You can disallow USB by changing group policies, third-party applications/tools are also available for disabling USB ports on Windows 10, i.e., SysTools USB blocker and USB block, etc.

.net core

.net core

NET Core Overview

.NET Core is a new version of .NET Framework, which is a free, open-source, general-purpose development platform maintained by Microsoft. It is a cross-platform framework that runs on Windows, macOS, and Linux operating systems.

.NET Core Framework can be used to build different types of applications such as mobile, desktop, web, cloud, IoT, machine learning, microservices, game, etc.

.NET Core is written from scratch to make it modular, lightweight, fast, and cross-platform Framework. It includes the core features that are required to run a basic .NET Core app. Other features are provided as NuGet packages, which you can add it in your application as needed. In this way, the .NET Core application speed up the performance, reduce the memory footprint and becomes easy to maintain.

Why .NET Core? 

There are some limitations with the .NET Framework. For example, it only runs on the Windows platform. Also, you need to use different .NET APIs for different Windows devices such as Windows Desktop, Windows Store, Windows Phone, and Web applications. In addition to this, the .NET Framework is a machine-wide framework. Any changes made to it affect all applications taking a dependency on it. Learn more about the motivation behind .NET Core .

Today, it's common to have an application that runs across devices; a backend on the web server, admin front-end on windows desktop, web, and mobile apps for consumers. So, there is a need for a single framework that works everywhere. So, considering this, Microsoft created .NET Core. The main objective of .NET Core is to make .NET Framework open-source, cross-platform compatible that can be used in a wide variety of verticals, from the data center to touch-based devices.

Overview of ASP.NET Core

ASP.NET Core is a cross-platform, high-performance, open-source framework for building modern, cloud-enabled, Internet-connected apps.

With ASP.NET Core, you can:

• Build web apps and services, Internet of Things (IoT) apps, and mobile backends.

• Use your favorite development tools on Windows, macOS, and Linux.

• Deploy to the cloud or on-premises.

• Run on .NET Core.

Why choose ASP.NET Core?

Millions of developers use or have used ASP.NET 4.x to create web apps. ASP.NET Core is a redesign of ASP.NET 4.x, including architectural changes that result in a leaner, more modular framework.

ASP.NET Core provides the following benefits:

• A unified story for building web UI and web APIs.

• Architected for testability.

• Razor Pages makes coding page-focused scenarios easier and more productive.

• Blazor lets you use C# in the browser alongside JavaScript. Share server-side and client-side app logic all written with .NET.

• Ability to develop and run on Windows, macOS, and Linux.

• Open-source and community-focused.

• Integration of modern, client-side frameworks and development workflows.

• Support for hosting Remote Procedure Call (RPC) services using gRPC.

• A cloud-ready, environment-based configuration system.

• Built-in dependency injection.

• A lightweight, high-performance, and modular HTTP request pipeline.

• Ability to host on the following:

• Kestrel

• IIS

• HTTP.sys

• Nginx

• Apache
• Docker

• Side-by-side versioning.

• Tooling that simplifies modern web development.

Client-side development

ASP.NET Core integrates seamlessly with popular client-side frameworks and libraries, including Blazor, Angular, React, and Bootstrap. For more information, see ASP.NET Core Blazor and related topics under Client-side development.

ASP.NET Core target frameworks

ASP.NET Core 3.x or later can only target .NET Core. Generally, ASP.NET Core is composed of .NET Standard libraries. Libraries written with .NET Standard 2.0 run on any .NET platform that implements .NET Standard 2.0.

There are several advantages to targeting .NET Core, and these advantages increase with each release. Some advantages of .NET Core over .NET Framework include:

• Cross-platform. Runs on Windows, macOS, and Linux.

• Improved performance

• Side-by-side versioning

• New APIs

• Open source. 

Characteristics of .NET Core

The following are the major characteristics of .NET Core −

Open source
Cross-platform
Flexible deployment
Command-line tools

Compatible
Modular

The .NET Core Platform

          Open source

• .NET Core is an open source implementation, using MIT and Apache 2 licenses.

• .NET Core is a .NET Foundation project and is available on GitHub.

• As an open source project, it promotes a more transparent development process and promotes an active and engaged community.

• Cross-platform

• Application implemented in .NET Core can be run and its code can be reused regardless of your platform target.

• It currently supports three main operating systems (OS)

  • ➣Windows

  • ➣Linux

  • ➣MacOS

• The supported Operating Systems (OS), CPUs and application scenarios will grow over time, provided by Microsoft, other companies, and individuals.

• Flexible deployment

• There can be two types of deployments for .NET Core applications −

  • ➣Framework-dependent ➣deployment

  • ➣Self-contained deployment

• With framework-dependent deployment, your app depends on a system-wide version of .NET Core on which your app and third-party dependencies are installed.

• With self-contained deployment, the .NET Core version used to build your application is also deployed along with your app and third-party dependencies and can run side-by-side with other versions.

• Command-line tools

• All product scenarios can be exercised at the command-line.

• .NET Core is compatible with .NET Framework, Xamarin and Mono, via the .NET Standard Library

• .NET Core is released through NuGet in smaller assembly packages.

• .NET Framework is one large assembly that contains most of the core functionalities.

• .NET Core is made available as smaller feature-centric packages.

• Compatible

• This modular approach enables the developers to optimize their app by including just those NuGet packages which they need in their app.

• Modular

• The benefits of a smaller app surface area include tighter security, reduced servicing, improved performance, and decreased costs in a pay-for-what-you-use model.

.NET Core Platform contains the following main parts −

• .NET Runtime − It provides a type system, assembly loading, a garbage collector, native interop and other basic services.

• Fundamental Libraries − A set of framework libraries, which provide primitive data types, app composition types and fundamental utilities.

• SDK & Compiler − A set of SDK tools and language compilers that enable the base developer experience, available in the .NET Core SDK.

• ‘dotnet’ app host − It is used to launch .NET Core apps. It selects the runtime and hosts the runtime, provides an assembly loading policy and launches the app. The same host is also used to launch SDK tools in much the same way.
