Shortly about backdoors
Is Trojan:Win32/SmokeLoader.YL dangerous?
As I have actually mentioned previously, non-harmful malware does not exist. And Trojan:Win32/SmokeLoader.YL is not an exception. This backdoor does not deal a lot of harm just after it launches. However, it will be a very bad surprise when an occasional online forum or website in the Web will not let you in, due to the fact that your IP-address is banned after the DDoS attack. However, even if it is not important for you – is it positive at all to know that somebody can easily access your computer, check out your conversations, open your documents, and spectate what you do?
The spyware that is frequently present as a supplement to the Trojan:Win32/SmokeLoader.YL virus will likely be just one more reason to remove it as fast as you can. Nowadays, when users’ information is priced exceptionally high, it is too illogical to provide the burglars such an opportunity. Even worse if the spyware will somehow handle to thieve your financial information. Seeing zeros on your financial account is the most awful headache, in my judgement.
How did I get this virus?
It is hard to trace the sources of malware on your PC. Nowadays, things are mixed up, and distribution ways chosen by adware 5 years ago can be utilized by spyware these days. But if we abstract from the exact spreading way and will think of why it has success, the answer will be very simple – low level of cybersecurity knowledge. Individuals click on advertisements on strange sites, click the pop-ups they receive in their browsers, call the “Microsoft tech support” assuming that the odd banner that states about malware is true. It is necessary to understand what is legitimate – to avoid misunderstandings when attempting to identify a virus.

Microsoft Tech Support Scam
Nowadays, there are two of the most common ways of malware spreading – lure emails and also injection into a hacked program. While the first one is not so easy to stay away from – you must know a lot to understand a counterfeit – the 2nd one is simple to address: just do not utilize hacked programs. Torrent-trackers and other sources of “totally free” applications (which are, exactly, paid, but with a disabled license checking) are just a giveaway point of malware. And Trojan:Win32/SmokeLoader.YL is simply among them.
