Windows Defender is a security application designed by Microsoft to help protect Windows users from a range of malicious threats. It is designed to detect and remove viruses, worms, trojans, rootkits, spyware, adware and other malicious programs, including phishing attacks and unwanted software. It also helps protect against ransomware, one of the most common and dangerous forms of cyberattack. It works by scanning your system for any suspicious activity, quarantining and removing any malicious files it finds.
Windows Defender helps protect users from many of the most common types of threats, including:
• Viruses – A virus is a malicious computer program that can spread from one computer to another. It can corrupt files, steal information and even render a computer unusable. Windows Defender can detect and remove viruses from your system before they can cause any harm.
• Trojans – A trojan is a type of malicious program that disguises itself as legitimate software. Once installed, it will allow an attacker to gain access to your system and monitor your activities. Windows Defender can detect and remove these dangerous programs.
• Spyware – Spyware is a type of malicious software that monitors your computer activity and collects data without your knowledge. Windows Defender can detect and remove spyware on your system.
• Adware – Adware is a type of software that displays advertisements while you are browsing the web or using your computer. It can be used to track your activities and collect information about you. Windows Defender can detect and remove adware on your system.
• Rootkits – Rootkits are malicious programs that are designed to hide themselves on your system and gain administrator-level access. This can be used to steal information, alter system settings and sabotage your computer. Windows Defender can detect and remove rootkits from your system.
• Phishing Attacks – Phishing attacks are fraudulent emails or websites designed to trick you into revealing sensitive information such as usernames, passwords and credit card numbers. Windows Defender can help protect against these attacks by identifying and blocking known phishing sites.
• Ransomware – Ransomware is a type of malicious software that restricts access to a computer system until a ransom is paid. It blocks access to important data and can render a computer unusable. Windows Defender can help protect against ransomware by quickly identifying and removing any malicious files on your system.
By using Windows Defender, you can help keep your system secure and protected from a variety of threats. It is important to note, however, that no security solution is perfect. It is still important to be cautious when downloading and installing programs, visiting websites and opening attachments.
