Any kind of malware exists with the only target – generate profits on you1. And the programmers of these things are not thinking of ethicality – they use all available ways. Stealing your private data, getting the comission for the banners you watch for them, exploiting your hardware 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 TrojanDropper:Win32/Kaymundler.B detection mean?

The TrojanDropper:Win32/Kaymundler.B detection you can see in the lower right corner is displayed to you by Microsoft Defender. That anti-malware application is quite OK at scanning, but prone to be generally unstable. It is unprotected to malware invasions, it has a glitchy interface and bugged malware removal features. Therefore, the pop-up which states concerning the Kaymundler is rather just an alert that Defender has found it. To remove it, you will likely need to use another anti-malware program.

The exact TrojanDropper:Win32/Kaymundler.B infection is a really unpleasant thing. It is present into your system disguised as a part of something benevolent, or as a part of the program you have got on a forum. Therefore, it makes all possible steps to make your system weaker. At the end of this “party”, it injects other malicious things – ones which are choosen by cybercriminals who control this malware. Hence, it is likely impossible to predict the effects from Kaymundler actions. And the unpredictability is one of the baddest things when we are talking about malware. That’s why it is better not to choose at all, and don’t give it even a single chance to complete its task.

Is TrojanDropper:Win32/Kaymundler.B dangerous?

As I have actually pointed out before, non-harmful malware does not exist. And TrojanDropper:Win32/Kaymundler.B is not an exception. This malware modifies the system settings, edits the Group Policies and registry. All of these components are critical for proper system operating, even when we are not talking about PC security. Therefore, the virus which Kaymundler contains, or which it will inject later, will try to get maximum profit from you. Crooks can grab your data, and then push it at the black market. Using adware and browser hijacker functions, embedded in TrojanDropper:Win32/Kaymundler.B virus, they can make profit by showing you the advertisements. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners per day – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.

How did I get this virus?

It is not easy to line the sources of malware on your PC. Nowadays, things are mixed, and distribution methods chosen by adware 5 years ago can be utilized by spyware nowadays. However, if we abstract from the exact spreading method and will think about why it has success, the explanation will be quite simple – low level of cybersecurity knowledge. People press on ads on odd sites, click the pop-ups they get in their browsers, call the “Microsoft tech support” assuming that the weird banner that states about malware is true. It is important to understand what is legit – to avoid misunderstandings when attempting to determine a virus.

Nowadays, there are two of the most widespread ways of malware distribution – bait e-mails and also injection into a hacked program. While the first one is not so easy to evade – you must know a lot to understand a fake – the 2nd one is very easy to solve: just do not use hacked programs. Torrent-trackers and other providers of “totally free” applications (which are, in fact, paid, but with a disabled license checking) are really a giveaway point of malware. And TrojanDropper:Win32/Kaymundler.B is simply among them.
