What does the Behavior:Win32/DNSRegistryChange.A virus mean?

The Behavior:Win32/DNSRegistryChange.A detection you can see in the lower right corner is shown to you by Microsoft Defender. That anti-malware software is quite OK at scanning, but prone to be generally unstable. It is unprotected to malware attacks, it has a glitchy user interface and bugged malware clearing capabilities. Hence, the pop-up which states about the DNSRegistryChange is rather just a notification that Defender has actually identified it. To remove it, you will likely need to use another anti-malware program.

The exact Behavior:Win32/DNSRegistryChange.A infection is a very undesirable thing. It sits into your PC under the guise of something legit, or as a part of the application you downloaded at a forum. Then, it makes all possible steps to make your system weaker. At the end of this “party”, it injects other malicious things – ones which are wanted by cybercriminals who control this virus. Hence, it is impossible to predict the effects from DNSRegistryChange actions. And the unpredictability is one of the baddest things when it comes to malware. That’s why it is rather not to choose at all, and don’t give it even a single chance to complete its task.

Is Behavior:Win32/DNSRegistryChange.A dangerous?

As I have pointed out before, non-harmful malware does not exist. And Behavior:Win32/DNSRegistryChange.A is not an exception. This malware alters the system configurations, edits the Group Policies and Windows registry. All of these things are critical for correct system operating, even in case when we are not talking about system safety. Therefore, the malware which DNSRegistryChange carries, or which it will inject later, will try to get maximum revenue from you. Crooks can steal your personal data, and then sell it on the Darknet. Using adware and browser hijacker functions, embedded in Behavior:Win32/DNSRegistryChange.A malware, they can make revenue 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 trace the sources of malware on your computer. Nowadays, things are mixed, and distribution tactics chosen by adware 5 years ago can be utilized by spyware nowadays. However, if we abstract from the exact spreading way and will think about why it works, the reply will be quite basic – low level of cybersecurity knowledge. Individuals press on promotions on weird websites, open the pop-ups they get in their browsers, call the “Microsoft tech support” believing that the scary banner that says about malware is true. It is essential to recognize what is legit – to avoid misconceptions when trying to figure out a virus.

Nowadays, there are two of the most extensive ways of malware spreading – lure e-mails and injection into a hacked program. While the first one is not so easy to avoid – you need to know a lot to recognize a counterfeit – the 2nd one is easy to solve: just do not utilize hacked applications. Torrent-trackers and various other providers of “totally free” applications (which are, exactly, paid, but with a disabled license checking) are just a giveaway place of malware. And Behavior:Win32/DNSRegistryChange.A is simply one of them.
