What is Behavior:Win64/AbuseCommBack.BK!sms virus?/h2>

The Behavior:Win64/AbuseCommBack.BK!sms detection you can see in the lower right side is demonstrated to you by Microsoft Defender. That anti-malware software is pretty good at scanning, however, prone to be generally unreliable. It is vulnerable to malware attacks, it has a glitchy user interface and problematic malware removal capabilities. Thus, the pop-up which states concerning the AbuseCommBack is simply an alert that Defender has identified it. To remove it, you will likely need to make use of another anti-malware program.

The exact Behavior:Win64/AbuseCommBack.BK!sms malware is a really undesirable thing. This malware is created to be a sneaky burglar, which works as a remote-access tool. When you give someone else remote access willingly, it is okay, but AbuseCommBack will not ask you if you wish to provide it. After connecting to your computer, criminals are free to do whatever they want – snatching your files, browsing your messages, gathering personal info, and so on. Backdoors usually bring an additional stealer – the virus that is designed to collect all possible data about you. Nonetheless, much more common use of the backdoors is forming the botnet. After that, the network of corrupted systems may be put to use to perform DDoS attacks or to inflate the survey results on different websites.

Shortly about backdoors

Backdoors are viruses that may acquire both separated and incorporated shapes. One time you can discover that an official program from a well-known developer has a functionality that enables somebody to connect to your computer. Will it be someone from the developers or a third party – no one knows. But the scandal when this fact is detected in an official program is pretty much impossible to miss. There is also gossip that there is a hardware-based backdoor in Intel CPUs1.

Is Behavior:Win64/AbuseCommBack.BK!sms dangerous?

As I have actually pointed out , non-harmful malware does not exist. And Behavior:Win64/AbuseCommBack.BK!sms is not an exception. This backdoor does not deal a lot of harm exactly after it launches. Nevertheless, it will be a pretty unpleasant surprise when a random online forum or site in the Internet will not let you in, because your IP-address is banned after the DDoS attack. However, even if it is not crucial for you – is it good at all to realise that someone else can easily access your PC, check out your discussions, open your files, as well as spectate what you do?

The spyware that is often present as a supplement to the Behavior:Win64/AbuseCommBack.BK!sms malware will likely be just another argument to remove it as fast as you can. Nowadays, when users’ information is valued very high, it is too illogical to grant the criminals such a chance. Even worse if the spyware will in some way handle to steal your financial info. Seeing zeros on your bank account is the worst problem, in my opinion.

How did I get this virus?

It is not easy to line the origins of malware on your computer. Nowadays, things are mixed, and distribution methods used by adware 5 years ago can be utilized by spyware nowadays. But if we abstract from the exact distribution method and will think about why it works, the reply will be pretty basic – low level of cybersecurity knowledge. People click on promotions on odd websites, open the pop-ups they receive in their browsers, call the “Microsoft tech support” believing that the scary banner that states about malware is true. It is very important to understand what is legitimate – to prevent misunderstandings when attempting to identify a virus.

Nowadays, there are two of the most widespread ways of malware distribution – lure emails and 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 second one is simple to solve: just do not utilize cracked apps. Torrent-trackers and other sources of “totally free” applications (which are, actually, paid, but with a disabled license checking) are really a giveaway place of malware. And Behavior:Win64/AbuseCommBack.BK!sms is simply among them.
