Trojan:Win32/SmokeLoader.GTB!MTB

If you spectate the alert of Trojan:Win32/SmokeLoader.GTB!MTB detection, it looks like that your computer has a problem. All malicious programs are dangerous, without any deviations. SmokeLoader provides the crooks access to your computer, or even connects it to the botnet.

What does the pop-up with Trojan:Win32/SmokeLoader.GTB!MTB detection mean?

The Trojan:Win32/SmokeLoader.GTB!MTB detection you can see in the lower right side is displayed to you by Microsoft Defender. That anti-malware application is quite OK at scanning, but prone to be mainly unreliable. It is vulnerable to malware invasions, it has a glitchy user interface and problematic malware clearing features. Thus, the pop-up which states about the SmokeLoader is rather just an alert that Defender has actually found it. To remove it, you will likely need to use a separate anti-malware program.

Microsoft Defender: “Trojan:Win32/SmokeLoader.GTB!MTB”

The exact Trojan:Win32/SmokeLoader.GTB!MTB virus is a very unpleasant thing. This malware is developed to be a sneaky burglar, which works as a remote-access tool. When you provide someone remote access willingly, it is OK, however, SmokeLoader will not ask you if you want to grant it. After connecting to your system, crooks are able to do whatever they want – snatching your files, browsing your messages, picking up personal information, and so on. Backdoors commonly bring an additional stealer – the virus that is designed to pick up all available data about you. Nevertheless, far more widespread use of the backdoors is forming the botnet. After that, the network of attacked PCs can be put to use to perform DDoS attacks or to inflate the poll results on different websites.

Shortly about backdoors

Is Trojan:Win32/SmokeLoader.GTB!MTB dangerous?

As I have mentioned previously, non-harmful malware does not exist. And Trojan:Win32/SmokeLoader.GTB!MTB is not an exclusion. This backdoor does not deal a lot of harm just after it introduces. However, it will likely be a very bad surprise when a random forum or website in the Web will not let you in, since your IP-address is disallowed after the DDoS attack. But even if it is not crucial for you – is it good at all to realise that somebody can easily access your computer, check out your discussions, open your documents, and spectate what you do?

The spyware that is usually present as a supplement to the Trojan:Win32/SmokeLoader.GTB!MTB virus will be just an additional reason to remove it as fast as you can. Nowadays, when users’ data is valued remarkably high, it is too illogical to give the burglars such a possibility. Even worse if the spyware will in some way manage to steal your banking information. Seeing 0 on your bank account is the worst problem, in my thoughts.

How did I get this virus?

It is not easy to trace the sources of malware on your PC. Nowadays, things are mixed up, and distribution ways utilized by adware 5 years ago may be used by spyware these days. But if we abstract from the exact spreading way and will think of why it works, the reply will be quite basic – low level of cybersecurity awareness. People press on promotions on odd websites, open the pop-ups they receive in their browsers, call the “Microsoft tech support” assuming that the strange banner that says about malware is true. It is necessary to know what is legit – to stay away from misconceptions when attempting to determine a virus.

Microsoft Tech Support Scam

Nowadays, there are two of the most widespread methods of malware spreading – lure emails and also injection into a hacked program. While the first one is not so easy to evade – you need to know a lot to recognize a counterfeit – the 2nd one is easy to address: just don’t use cracked apps. Torrent-trackers and other sources of “free” applications (which are, actually, paid, but with a disabled license checking) are really a giveaway place of malware. And Trojan:Win32/SmokeLoader.GTB!MTB is simply within them.
