What viruses can Windows Defender detect?

Microsoft Windows Defender is a software program designed to protect computers from malware, viruses, and other malicious threats. It is an antivirus solution that comes preinstalled on Windows-based systems and can be purchased as a standalone product. It provides real-time protection against viruses, spyware, ransomware, rootkits, and other malicious programs.

Windows Defender is capable of detecting a wide variety of viruses, including the following:

1. Worms: These programs are self-replicating, and they can spread quickly through networks or files. They can cause network congestion and system instability. Common worms include Sasser, Slammer, Sober, Code Red, Blaster, and Nimda.

2. Trojan Horses: Also known as “Trojan”, these malicious programs install malicious code onto a computer without the user’s knowledge or consent. They can access important system files or give attackers access to the computer. Common Trojans include Subseven, WinHole, Back Orifice, and Netbus.

3. Adware: This type of program displays unwanted advertisements on the user’s computer. The ads are usually generated by third-party companies and are displayed when the user browses certain websites or downloads certain software applications.

4. Spyware: This type of program monitors the user’s activity without their permission or knowledge. It can collect personal information such as passwords, banking details, and browsing habits. Common examples include CoolWebSearch, SpyAxe, and Gator.

5. Ransomware: This type of program encrypts the user’s files until they pay a ransom. It can be used to extort money from users, or it can simply be used to make them uninstall the program. Common ransomware include CryptoLocker, WannaCry, and NotPetya.

6. Rootkits: These programs are designed to hide malicious code on a computer. They can be used to install backdoors and allow attackers to gain access to the system without detection. Common rootkits include FU, GMER, and TDL4.

7. Browser Hijackers: These programs are designed to change the user’s browser settings without their knowledge or consent. This can include changing the homepage, search engine, and default web page. Common hijackers include Conduit, Qvo6, and Babylon.

8. Fake Anti-Virus Programs: These are malicious programs disguised as security software. They are designed to trick users into buying them or installing them on their computers. Common fake anti-virus programs include System Cleaner, Advanced Virus Remover, and Antivir Gear.

In addition to the aforementioned types of viruses and malware, Windows Defender is also capable of detecting numerous other types of malicious programs, including keyloggers, Potentially Unwanted Programs (PUPs), and cryptocurrency miners. As technology evolves and new types of malicious programs emerge, Windows Defender continues to update its virus definitions to ensure maximum protection against the latest threats.
