What does the notification with Trojan:Win32/Leonem.4AB detection mean?

The Trojan:Win32/Leonem.4AB detection you can see in the lower right side is shown to you by Microsoft Defender. That anti-malware software is pretty good at scanning, but prone to be basically unreliable. It is prone to malware invasions, it has a glitchy user interface and bugged malware removal capabilities. Hence, the pop-up which says concerning the Leonem is just an alert that Defender has found it. To remove it, you will likely need to make use of another anti-malware program.

The exact Trojan:Win32/Leonem.4AB infection is a really undesirable thing. It sits inside of your system under the guise of something legit, or as a part of the tool you have got on a forum.

Is Trojan:Win32/Leonem.4AB dangerous?

As I have stated , non-harmful malware does not exist. And Trojan:Win32/Leonem.4AB is not an exception. This virus modifies the system settings, 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 PC safety. Therefore, the malware which Leonem carries, or which it will inject later, will try to get maximum profit from you. Cybercriminals can steal your personal information, and then push it at the black market. Using adware and browser hijacker functionality, embedded in Trojan:Win32/Leonem.4AB malware, they can make profit by showing you the ads. 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 origins of malware on your PC. Nowadays, things are mixed up, and distribution methods used by adware 5 years ago may be utilized by spyware nowadays. But if we abstract from the exact spreading tactic and will think about why it has success, the reply will be very basic – low level of cybersecurity knowledge. Individuals press on promotions on strange websites, open the pop-ups they get in their web browsers, call the “Microsoft tech support” assuming that the odd banner that says about malware is true. It is essential to know what is legit – to prevent misunderstandings when attempting to determine a virus.

While the first one is not so easy to stay away from – you need to know a lot to recognize a fake – the second one is simple to get rid of: just do not utilize cracked programs. Torrent-trackers and other providers of “free” applications (which are, actually, paid, but with a disabled license checking) are really a giveaway place of malware. And Trojan:Win32/Leonem.4AB is simply among them.
