Any type of malware exists with the only target – make money on you1. And the programmers of these things are not thinking about morality – they use all possible methods. Stealing your personal data, receiving the comission 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 horse? That is a rhetorical question.

What does the notification with Trojan:Win32/AgentTesla detection mean?

The Trojan:Win32/AgentTesla detection you can see in the lower right side is demonstrated to you by Microsoft Defender. That anti-malware program is good at scanning, however, prone to be generally unreliable. It is defenseless to malware attacks, it has a glitchy user interface and problematic malware clearing features. Thus, the pop-up which states about the AgentTesla is just an alert that Defender has actually found it. To remove it, you will likely need to make use of a separate anti-malware program.

The exact Trojan:Win32/AgentTesla virus is a really undesirable thing. It sits into your Windows under the guise of something legitimate, or as a piece of the tool you have got on a forum. Therefore, it makes everything to weaken your system. At the end of this “party”, it injects other viruses – ones which are wanted by cybercriminals who manage this malware. Hence, it is likely impossible to predict the effects from AgentTesla actions. And the unpredictability is one of the most unwanted 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 Trojan:Win32/AgentTesla dangerous?

As I have stated , non-harmful malware does not exist. And Trojan:Win32/AgentTesla is not an exception. This malware alters the system setups, modifies the Group Policies and Windows registry. All of these components are vital for proper system functioning, even in case when we are not talking about system safety. Therefore, the virus which AgentTesla carries, or which it will inject later, will try to get maximum profit from you. Cyber burglars can steal your personal data, and then push it at the black market. Using adware and browser hijacker functions, embedded in Trojan:Win32/AgentTesla malware, 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 difficult to trace the origins of malware on your PC. Nowadays, things are mixed up, and spreading ways used 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 reply will be very basic – low level of cybersecurity understanding. People click on advertisements on strange websites, click the pop-ups they receive in their web browsers, call the “Microsoft tech support” believing that the odd banner that says about malware is true. It is important to recognize what is legit – to stay away from misconceptions when trying to identify a virus.

Torrent-trackers and other providers of “free” applications (which are, actually, paid, but with a disabled license checking) are just a giveaway point of malware. And Trojan:Win32/AgentTesla is simply amongst them.
