What type of threats does Windows Defender detect?

Windows Defender is a security application built into the Windows Operating System. It provides protection against malicious software including viruses, rootkits, spyware, and ransomware. Windows Defender, which is also known as Microsoft Defender, offers real-time protection from malicious threats, allowing users to be secure while they work, play, and browse the web.

Windows Defender detects a variety of threats such as viruses, worms, Trojans, rootkits, spyware, adware, and potentially unwanted programs (PUPs). The antivirus program scans for known malicious signatures on all downloaded files and programs, and then takes action if it finds something suspicious.

Viruses are the most common type of threat that Windows Defender can detect and protect against. These malicious programs can enter your computer through email attachments or by downloading infected files and applications. Once they are on your PC, they can wreak havoc and even permanently damage or delete your data or system. Windows Defender runs continual scans and can detect and remove these viruses if it finds any.

Worms are another type of malware that Window Defender can detect. Worms spread quickly and can cause serious damage to your system. They can use up your computer’s resources, corrupt files, create backdoors, and spread themselves to other computers. Windows Defender recognizes the signatures of known worms and can remove them before they cause any harm.

Rootkits are often combined with other malicious programs like viruses and worms. Rootkits can be used to gain access to system files and install hidden software. Windows Defender scans for rootkits and can help you safely remove them using its specialized rootkit scanning tool. This ensures that your data and system remain safe and secure.

Spyware is often installed without your knowledge and can track your activities, steal private information, and even redirect you to fake websites. Windows Defender can detect spyware by scanning all downloaded files and programs, and will block any suspicious activity.

Adware can be found in different forms such as pop-up ads, banner ads, and other forms of intrusive advertising. Although this type of malware is generally not as dangerous as viruses and worms, it can still be annoying and slow down your system performance. Windows Defender can scan for adware and prevent it from taking control over your system.

Potentially Unwanted Programs (PUPs) are applications that may have legitimate uses but can also contain malicious code, such as tracking cookies and other spyware. Windows Defender can detect the malicious components of PUPs and alert you if any are present.

Windows Defender is an effective tool for detecting malicious threats and keeping your system safe and secure. It can detect a wide range of threats including viruses, worms, rootkits, spyware, adware, and potentially unwanted programs. By running frequent scans, Windows Defender can help you stay protected and secure while browsing the web and using your computer.
