Any malware exists with the only target – make money on you1. And the developers of these things are not thinking about ethicality – they utilize all available methods. Taking your private data, receiving the payments for the ads you watch for them, exploiting your CPU and GPU to mine cryptocurrencies – that is not the complete list of what they do. Do you like to be a riding steed? That is a rhetorical question.

What does the notification with Backdoor:Win32/Mydoom.gen detection mean?

The Backdoor:Win32/Mydoom.gen detection you can see in the lower right side is shown to you by Microsoft Defender. That anti-malware software is quite OK at scanning, but prone to be mainly unstable. It is vulnerable to malware invasions, it has a glitchy user interface and problematic malware clearing capabilities. Therefore, the pop-up which says about the Mydoom is rather just a notification that Defender has identified it. To remove it, you will likely need to make use of another anti-malware program.

The exact Backdoor:Win32/Mydoom.gen virus is a really unpleasant thing. This malware is created to be a stealthy trespasser, which acts as a remote-access tool. When you provide somebody remote access willingly, it is okay, but Mydoom will not ask you if you would like to give it. After connecting to your PC, crooks are able to do whatever they want – grabbing your files, browsing your messages, picking up personal information, and so on. Backdoors usually carry an additional stealer – the virus that is made to gather all available information about you. Nevertheless, far more prevalent use of the backdoors is establishing the botnet. After that, the network of attacked computers can be put to use to perform DDoS attacks or to inflate the survey results on various web pages.

Shortly about backdoors

Backdoors are viruses that may obtain both separated and built-in forms. One time you can discover that an official program from a well-known developer has a capability that makes it possible for someone to connect to your system. Will it be someone from the developers or a third party – no one knows. However, the scandal when this feature is uncovered in a legit program is nearly impossible to miss. There is also gossip that there is a hardware-based backdoor in Intel CPUs2.

Is Backdoor:Win32/Mydoom.gen dangerous?

As I have mentioned previously, non-harmful malware does not exist. And Backdoor:Win32/Mydoom.gen is not an exception. This backdoor does not deal a lot of damage just after it releases. Nevertheless, it will be a really unpleasant surprise when an occasional online forum or page in the Web will not let you in, because your IP-address is disallowed after the DDoS attack. However, even if it is not critical for you – is it pleasing at all to realize that somebody can easily access your computer, check out your discussions, open your documents, and spectate what you do?

The spyware that is often present as a supplement to the Backdoor:Win32/Mydoom.gen virus will likely be just an additional reason to remove it as fast as you can. Nowadays, when users’ data is valued exceptionally high, it is too goofy to give the criminals such an opportunity. Even worse if the spyware will somehow manage to steal your banking information. Seeing 0 on your bank account is the worst nightmare, in my point of view.

How did I get this virus?

It is not easy to line the sources of malware on your computer. Nowadays, things are mixed up, and spreading methods chosen by adware 5 years ago can be used by spyware nowadays. However, if we abstract from the exact spreading tactic and will think of why it has success, the explanation will be pretty basic – low level of cybersecurity knowledge. People press on promotions on strange websites, open the pop-ups they get in their browsers, call the “Microsoft tech support” assuming that the strange banner that says about malware is true. It is very important to recognize what is legit – to stay away from misunderstandings when attempting to identify a virus.

Nowadays, there are two of the most common methods of malware distribution – lure emails and also injection into a hacked program. While the first one is not so easy to evade – you must know a lot to recognize a counterfeit – the second one is very easy to handle: just do not utilize cracked applications. Torrent-trackers and other sources of “free” applications (which are, in fact, paid, but with a disabled license checking) are just a giveaway point of malware. And Backdoor:Win32/Mydoom.gen is just within them.
