What does the notification with Trojan:Win32/Redline.KB!MTB detection mean?

The Trojan:Win32/Redline.KB!MTB detection you can see in the lower right side is displayed to you by Microsoft Defender. That anti-malware application is good at scanning, but prone to be basically unreliable. It is unprotected to malware invasions, it has a glitchy interface and bugged malware removal capabilities. Hence, the pop-up which states concerning the Redline is rather just a notification that Defender has recognized it. To remove it, you will likely need to use another anti-malware program.

Having Trojan:Win32/Redline.KB!MTB malware on your PC is not a pleasant thing from any perspective. The most troublesome issue is that you will not discover anything wrong. A key quality of any spyware is being as stealthy as possible. Some Redline samples also can perform self-destruction after grabbing all the data present in the system. After that, it will be almost impossible to uncover the flow of events and figure out how your accounts were hacked.

Is Trojan:Win32/Redline.KB!MTB dangerous?

As I said before, any malware is harmful. And Trojan:Win32/Redline.KB!MTB is not even close to making more disturbance than real damage. The most misleading feature of Redline is the fact you cannot witness its activity in any way, other than with anti-malware software scanning. And when you are in the dark, cybercriminals who successfully implemented their nasty thing to your computer are starting to count the money. Darknet offers a lot of opportunities to sell spyware logs for a hefty sum – especially when these logs are new. And you’d better not imagine what will happen to your accounts when other rascals will put their hands on your login credentials.

However, situation may have much faster flow. In some cases, hackers are delivering their virus precisely to the user they are going to steal from. Spyware is priceless when it comes to grabbing credentials, and some examples target precisely at banking accounts or crypto wallets. One may say, giving spyware a run equals to sending all your money to criminals.

How did I get this virus?

It is hard to trace the origins of malware on your computer. Nowadays, things are mixed, and distribution ways utilized by adware 5 years ago can be used by spyware nowadays. But if we abstract from the exact spreading method and will think of why it works, the answer will be pretty simple – low level of cybersecurity awareness. Individuals click on promotions on weird sites, open the pop-ups they get in their web browsers, call the “Microsoft tech support” assuming that the scary banner that states about malware is true. It is essential to understand what is legitimate – to prevent misunderstandings when trying to determine a virus.

Nowadays, there are two of the most extensive methods of malware spreading – lure e-mails and injection into a hacked program. While the first one is not so easy to avoid – you must know a lot to recognize a counterfeit – the 2nd one is simple to address: just don’t utilize cracked apps. Torrent-trackers and various other providers of “free” applications (which are, in fact, paid, but with a disabled license checking) are just a giveaway point of malware. And Trojan:Win32/Redline.KB!MTB is just within them.

How to remove the Trojan:Win32/Redline.KB!MTB from my PC?
