Any kind of malware exists with the only target – generate profits on you1. And the programmers of these things are not thinking about ethicality – they utilize all possible ways. Taking your private data, getting the payments for the advertisements you watch for them, utilizing your PC 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 TrojanDownloader:Win32/Upatre!rfn detection mean?
The TrojanDownloader:Win32/Upatre!rfn detection you can see in the lower right corner is demonstrated to you by Microsoft Defender. That anti-malware application is quite OK at scanning, but prone to be generally unreliable. It is vulnerable to malware invasions, it has a glitchy interface and bugged malware removal capabilities. Hence, the pop-up which says about the Upatre is rather just a notification that Defender has actually found it. To remove it, you will likely need to use a separate anti-malware program.

The exact TrojanDownloader:Win32/Upatre!rfn virus is a really undesirable thing. It digs into your computer under the guise of something legit, or as a part of the app you downloaded at a forum. After that, it makes everything to make your system weaker. At the end of this “party”, it downloads other malicious things – ones which are wanted by crooks who control this malware. Hence, it is likely impossible to predict the effects from Upatre actions. And the unpredictability is one of the most upleasant things when it comes to 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 TrojanDownloader:Win32/Upatre!rfn dangerous?
As I have specified , non-harmful malware does not exist. And TrojanDownloader:Win32/Upatre!rfn is not an exception. This malware modifies the system configurations, modifies the Group Policies and Windows registry. All of these things are crucial for proper system functioning, even in case when we are not talking about system safety. Therefore, the malware which Upatre carries, or which it will inject after some time, will try to get maximum profit from you. Cyber burglars can steal your data, and then push it at the black market. Using adware and browser hijacker functionality, built in TrojanDownloader:Win32/Upatre!rfn malware, they can make money by showing you the banners. 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 hard to line the sources of malware on your PC. Nowadays, things are mixed, and spreading methods used by adware 5 years ago can be used by spyware these days. However, if we abstract from the exact distribution tactic and will think of why it works, the answer will be very uncomplicated – low level of cybersecurity understanding. People click on ads on odd websites, click the pop-ups they get in their web browsers, call the “Microsoft tech support” thinking that the weird banner that states about malware is true. It is important to recognize what is legitimate – to prevent misconceptions when attempting to identify a virus.

Nowadays, there are two of the most common tactics of malware distribution – bait e-mails and also injection into a hacked program. While the first one is not so easy to stay away from – you need to know a lot to understand a counterfeit – the 2nd one is easy to address: just don’t use cracked apps. Torrent-trackers and other providers of “totally free” applications (which are, in fact, paid, but with a disabled license checking) are just a giveaway place of malware. And TrojanDownloader:Win32/Upatre!rfn is simply within them.
