As part of the Microsoft Windows operating system, HP PCs come with Windows Defender Antivirus pre-installed. Yes, an antivirus application is already installed on your HP laptop or desktop computer as part of the Windows suite. In many circumstances, you won't need any extra antivirus software to keep your HP laptop safe. However, there are times when you may want to install another antivirus program. For example, if you use a secondary device like a tablet or smartphone to browse the web, you might want to have antivirus software running in the background.
Windows Defender includes some features that can help protect your computer against viruses and other malicious software. These include:
• Automatic updates. Windows Defender monitors for new versions of itself and automatically installs them before they're available manually. This means that you don't have to do anything special to stay protected—Windows Defender will take care of it.
• Behavior monitoring. Windows Defender watches what programs run and how they interact with other programs and objects on your computer. It uses this information to determine whether or not a program is likely to be harmful before allowing it to run. If Windows Defender detects that a program is behaving suspiciously (e.g., opening email from unknown sources), it will disable that program until you tell it to allow it again.
• Clipping. Windows Defender includes basic clipping detection technology.
It's no secret that Windows PCs have their own antivirus software, known as Windows Defender or Microsoft Defender Antivirus. Many people, however, question if Windows Defender is sufficient to guard against viruses, spyware, and the like. The short answer is yes, it comes pre-installed with Windows.
Windows Defender is not only capable of detecting viruses, but it can also remove them from your computer automatically. It uses a combination of heuristics, which are rules used by computers to identify malware, and signature files, which are lists of known bad code. When Windows Defender encounters new code, it will first try to determine whether or not it is harmful using heuristics, and if necessary it will scan it with its signature file to confirm that it is not infected.
Windows Defender is free and available for all Windows versions starting with Windows 7. It can be enabled through the Windows Control Panel. By default, it will be activated on every PC when you install Windows, but you can change this setting in the Control Panel after installation has completed if you want to disable it or use another antivirus product instead.
You should know that while Windows Defender is useful, it is not meant to be your only form of antivirus protection. It is recommended that you use it in conjunction with another antivirus application so that each one can help the other find infected files.
Almost all versions of Microsoft Windows do not come with an antivirus protection package pre-installed. An antivirus application can be installed later via Windows Update or using other third-party software. Most people should consider installing an antivirus program anyway, even if they are not sick with a virus. A healthy PC will be less likely to catch a virus.
The advantage of having an antivirus program running is that it can scan your computer for viruses every few minutes. This allows it to find viruses which others might not catch immediately. It also prevents viruses from doing any damage before you notice them. Disadvantages include making your computer more resource intensive and slowing it down. Having an antivirus program also means that you will need to deal with alerts when there is something it doesn't like about your system settings or new programs.
Windows itself has some built-in security features. For example, Windows Firewall helps prevent unauthorized individuals from accessing your computer remotely. Also, Windows will automatically update Windows itself when an update is available. These types of features should be enabled so that they can protect your computer if you don't use an antivirus application.
Windows has had virus protection for many years, and the most recent edition, included in Windows 10, is the most powerful it has ever been. If your laptop or PC did not arrive with any additional antivirus software pre-installed, Windows Defender will automatically secure your machine. There are some features of some other programs that are not compatible with Windows 10's version of Defender, so if you install another antivirus program you should disable it or remove its application directory before continuing on to the next step.
Microsoft does release security updates for older versions of Windows, but they are called "patches" and can only fix problems with known vulnerabilities. For example, when an unknown vulnerability is discovered in Google Chrome, it issues a patch to fix it; this is called a "security update." Older versions of Windows require users to download and apply these patches themselves - or have someone who knows what they're doing do it for them. Unfortunately, this means that old computers are at risk of being infected by new viruses.
Laptops are particularly vulnerable because they tend to be customized by their owners, who may install their own programs instead of using Windows' default setup. This can leave older machines susceptible to malware attacks. Even though Windows 10 includes its own anti-virus program, it can't protect your computer if you don't use it.
