Worm:Win32/Alcan.B Backdoor Virus (Alcan Removal)

Written by Wilbur Woodham

The Worm:Win32/Alcan.B detection means that your PC has a problem. Allowing it to keep running may lead to really bad consequences. Alcan gives the burglars an easy access to your computer, or even adds it to the botnet.

Backdoors like Alcan are versatile viruses that may act as autonomous malware, or be used in staged attacks. Their key purpose is to create a remote control point to the system, that operates without the owner’s knowledge. To prevent any interruptions, malware tries to stay as stealthy as possible.

Worm:Win32/Alcan.B Detection Overview

The Worm:Win32/Alcan.B detection you can see in the lower right corner is shown to you by Microsoft Defender. That anti-malware program is quite OK at scanning, however, prone to be mainly unstable. It is prone to malware attacks, it has a glitchy user interface and bugged malware clearing capabilities. Hence, the pop-up which says about the Alcan is simply a notification that Defender has actually recognized it. To remove it, you will likely need to make use of a separate anti-malware program.

The exact Worm:Win32/Alcan.B malware is a really nasty thing. This malware is created to be a sneaky intruder, which acts as a remote-access tool. When you provide someone remote access willingly, it is OK, but Alcan will not ask you if you wish to provide it. After connecting to your system, crooks are able to do whatever they want – getting your files, examining your messages, collecting personal data, et cetera. Backdoors commonly bring an additional stealer – the virus that is developed to gather all available information about you. Nevertheless, a lot more common use of the backdoors is creating the botnet. Then, the network of infected systems may be used to conduct DDoS attacks or to inflate the survey results on different websites.

Shortly about backdoors

Backdoors are viruses that may obtain both separated and built-in shapes. One time you can uncover that an official program from a well-known company has a functionality that makes it possible for someone to connect to your computer. Will it be someone from the creators or a 3rd party – no one knows. However, the scandal when this feature is uncovered in an official program is nearly impossible to miss. There is also chatter that there is a hardware-based backdoor in Intel CPUs1.

Is Worm:Win32/Alcan.B dangerous?

As I have actually specified previously, non-harmful malware does not exist. And Worm:Win32/Alcan.B is not an exception. This backdoor does not deal a lot of harm just after it introduces. However, it will be a very bad surprise when an occasional online forum or website in the Internet will not let you in, because your IP-address is disallowed after the DDoS attack. However, even if it is not vital for you – is it pleasurable in any way to realise that somebody can easily access your computer, read your discussions, open your documents, and spectate what you do?

The spyware that is often present as a supplement to the Worm:Win32/Alcan.B malware will likely be just another reason to remove it as fast as you can. Nowadays, when users’ data is valued very high, it is too illogical to grant the crooks such a chance. Even worse if the spyware will in some way manage to grab your banking info. Seeing 0 on your financial account is the most awful headache, in my opinion.
