Any kind of malware exists with the only target – make money on you1. And the programmers of these things are not thinking of morality – they utilize all available ways. Stealing your private data, receiving payments for the banners you watch for them, exploiting your system to mine cryptocurrencies – that is not the complete list of what they do. Do you want to be a riding horse? That is a rhetorical question.

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

The Trojan:Win32/SmokeLoader.PA!MTB detection you can see in the lower right side is demonstrated to you by Microsoft Defender. That anti-malware program is good at scanning, but prone to be generally unreliable. It is defenseless to malware invasions, it has a glitchy user interface and bugged malware removal features. Hence, the pop-up which states concerning the SmokeLoader is rather just a notification that Defender has identified it. To remove it, you will likely need to make use of a separate anti-malware program.

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

The exact Trojan:Win32/SmokeLoader.PA!MTB virus is a very unpleasant thing. This malware is created to be a stealthy intruder, which serves as a remote-access tool. When you provide someone else remote access willingly, it is OK, however, SmokeLoader will not ask you if you wish to grant it. After connecting to your computer, crooks are free to do whatever they want – snatching your files, reading your messages, collecting personal data, et cetera. Backdoors frequently bring a supplementary stealer – the virus that is developed to collect all possible information about you. However, a lot more popular use of the backdoors is creating the botnet. Then, the network of attacked computers may be put to use to perform DDoS attacks or to inflate the poll results on different websites.

Shortly about backdoors

Backdoors are viruses that can acquire both separated and incorporated shapes. One time you can uncover that a legitimate program from a widely known developer has a functionality that enables someone to connect to your PC. Will it be somebody from the creators or a third party – nobody knows. However, the scandal when this aspect is detected in an official program is nearly impossible to miss. There is also gossip that there is a hardware-based backdoor in Intel CPUs2.

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

As I have mentioned previously, non-harmful malware does not exist. And Trojan:Win32/SmokeLoader.PA!MTB is not an exception. This backdoor does not deal a many harm just after it introduces. Nonetheless, it will likely be a really unpleasant surprise when a random discussion forum or website in the Web will not let you in, because your IP-address is disallowed after the DDoS attack. However, even if it is not vital for you – is it enjoyable in any way to understand that somebody can easily access your PC, read your conversations, open your documents, as well as spectate what you do?

The spyware that is usually present as a supplement to the Trojan:Win32/SmokeLoader.PA!MTB malware will likely be just another reason to remove it as fast as you can. Nowadays, when users’ information is valued exceptionally high, it is too illogical to provide the crooks such a chance. Even worse if the spyware somehow manages to grab your financial info. Seeing zeros on your bank account is the most awful headache, in my judgement.

How did I get this virus?

It is hard to line the origins of malware on your PC. Nowadays, things are mixed, and spreading methods chosen by adware 5 years ago can be utilized by spyware these days. However, 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 understanding. Individuals click on advertisements on strange sites, open the pop-ups they receive in their browsers, and call “Microsoft tech support” thinking that the odd banner that states about malware is true. It is necessary to recognize what is legit – to prevent misunderstandings when attempting to identify a virus.

While the first one is not so easy to stay away from – you must know a lot to recognize a counterfeit – the second one is very easy to address: just don’t utilize hacked applications. Torrent-trackers and various other providers of “free” applications (which are, actually, paid, but with a disabled license checking) are just a giveaway place of malware. And Trojan:Win32/SmokeLoader.PA!MTB is just among them.
