Windows Defender is a malware removal tool included with Windows 8, Windows 8.1 and Windows Server 2012. This article details some of its problems in removing malware. For example, it was unable to detect a Trojan threat, Trojan.Win32.Zbot.gen, despite being advised to do so by a Symantec virus scanner. If you use Windows Defender, you may want to install a third-party anti-malware program. We’ve been seeing a lot of reports lately that Microsoft’s Windows Defender anti-malware software is failing to remove a huge number of malicious applications that were detected as Trojan threats. A recent one found on a user’s computer was a fake image file that contained a nasty Trojan. It was removed by the user, but not before Windows Defender removed it from the system.
Despite Windows Defender, some malware that hijacks legitimate files and Internet traffic remains undetected for years. A Trojan infection that the user thinks is a social media app may infect the machine, but the antivirus software wouldn’t remove it. Malware that hijacks Web traffic is another sneaky way to get access to a machine, and the user won’t know for years that it’s there. Overall, it provides comprehensive protection against the most advanced threats, and it is sure to detect Trojans on your system and remove them immediately.

Frequently asked questions
Can Microsoft Defender remove Trojans?
Windows Defender is an anti-malware utility integrated into the Windows operating system. It automatically scans, detects and removes potentially unwanted software (PUP) including computer viruses, spyware, trojans and rootkits. Despite its popularity, Windows Defender has been a source of numerous privacy concerns for many users, especially those who were tricked into installing them after facing annoying pop-up ads. The latest discovery, posted by MalwareHunterTeam on Reddit, shows that Defender fails to remove a Trojan, even when it is set to run at startup. The team discovered this by creating a malicious executable file, and then setting Windows Defender to automatically scan and remove it. However, the file was not removed, and the user’ Microsoft has been updating the Windows Defender app since its launch on Windows Vista back in 2007. This year, it finally got a major update to add additional features and protect users from new threats. In this post, we look at the new features added to Windows Defender in Windows 8, and we see how the app can help you remove Trojans that use rootkit techniques.
Does Windows Defender automatically remove threats?
I recently installed Windows Defender on my Windows 10 laptop, and it is the first time I got it to work fully. I have, however, noticed that, while Windows Defender does a great job taking care of real threats, it fails to remove some types of malware. Windows Defender is a great security tool, as it gives you the option to scan files and apps without having to install them. But there are situations in which you’re likely to have a virus that will not be removed by the built in scanner. In particular, Windows Defender fails when dealing with Trojan threats.
Can Windows Defender find Trojans?
You probably already know that Windows Defender doesn’t actually remove malware; it merely scans it for any known signatures, and leaves any that are not recognized as malicious. However, an independent security researcher recently discovered a new method for bypassing Windows Defender. The researcher, using a special tool called Handbrake, managed to fool Windows Defender into removing a Trojan virus. Although it is an extremely rare thing to happen, it is important to be aware that it is a real threat. Windows Defender has a reputation of being a poor security program, and one of the reasons is that it is unable to identify a lot of dangerous threats. Microsoft’s security suite has lacked the ability to find and remove certain types of intrusions, including Trojans. In a blog post, a user of the Windows Defender Security Center claims that the product has been unable to clean up a Trojan infection for several months.
