Beware! - 3 common types of malware


What is malware?

Malicious software is called malicious software, which only creates the appearance of a legal and proven program, and actually tries to persuade users to download it. One of the most commonly used treatments is the offer of special promotions or rewards, which are supposed to make the user download them to his device. The intention of malicious software is to access stored data or to operate without the consent of the owner of the device. Recently, a large number of such programs have appeared at the moment of displaying intrusive advertising (adware), which takes over confidential and sensitive data (spyware).

Here are the three most common types of malware, which every user surfing the Internet should be aware of and from which they should protect themselves.


A group of pests that tries to put new records on a user's computer or force the user to open a specific link. According to the scenario, a computer infected by software needs to restore the factory settings for which you have to pay. Usually Win32/Crowti appears on the device in the form of a spam message received in an e-mail inbox.

Additionally, this threat may be placed on the device by another virus, e.g. Trojandownloader.Small.ZL: Win32 / Onkods or Trojandownloader.Small.ZL: Win32 / Upatre.


Malware from the BlackEnergy family was created to carry out DDoS attacks, spread spam and bank tricks and scams. In order to reach a large group of users and infect the device, the virus uses vulnerabilities, action messages and downloads of defective versions of Microsoft Word, PowerPoint or a combination of both.

Infection of the device by the BlackEnergy virus takes place through the use of shellcode, which in the form of two records or files is placed in a permanent or temporary directory of the computer.



Last but not least, the versatile Andr/BBridge-A trojan virus. It is known primarily for the fact that it collects confidential information from customers or users, such as specific subscriber ID, IMEI - individual mobile phone identification number, phone number, ISO network country, phone model, Android OS version and sim card information. This happens on a specific server depending on the HTTP protocol.

Here are some tips on how to protect your device from various types of malware:

Do not enter suspicious websites and do not click on links that you are not sure where they lead. One of the signs that shows that you are on a suspicious website are pop-ups in countless windows (called pop ups).

Do not open suspicious e-mail messages if you do not know the sender of the message or the address from which the e-mail was sent is strangely saved. This also applies to links sent in messages - never open them.

The best solution is to install virus protection. Malware evolves at a very fast pace, so it is important to keep your device protection tools up to date.
