Is it possible to create a virus that does not cause any suspicion of its presence? Is there a universal way to evade all existing security software, even if this way will be done open to the public? Is it possible to execute random code on a remote machine without any notification to a user and unnoticed for "artificial intelligence"?

The immediate sketch on the theme "My security is in my hands." In this article the author describes in detail the cure system procedure for malware Trojan-Ransom.Win32.Chameleon. It is very topical and useful lesson.

At this time I will narrate about Trojan-Ransom.Win32.Chameleon.

The History of Trojan-Ransoms according to Kaspersky Lab started in 2005 with a Trojan-Ransom.Win32.Krotten family. The Trojan disabled many system functions using the system registry. For example, it blocked the closing of Windows Explorer and disabled Task Manager and Registry Editor...

Recently, the popularity of the malicious programs that have a functional of worm used to spread malware via removable storage medium is constantly growing (e.g. USB sticks). In this article we will narrate about this type of malware and how to combat against it.

The study of history is a necessary and important occupation. Knowledge of the history allows you sometimes to see important regularities. Studying of the malicious programs history is not less fascinating than the studying of the country history.

The important feature of the malicious programs history is that everything happens almost in the one generation's memory. In addition, it is related with computers and Internet, and it means that the information is always available and securely stored. That is why, even after a lapse of time you can easily get information about past events.

In this article we will address the topic, about which everyone has heard a lot, but not always can define what is this in fact. The information provided below will allow looking at this issue from the professional standpoint of security analyst. You will not find a tearjerker about how John or Nick hacked a popular website, having read the appropriate guidance on haker.com or in blog of a popular hacker :)

This time I would like to narrate about malicious programs designed for Linux Operating System.

We hear periodically that "there are no malicious programs specifically written for Linux". And I have used the "Virus Watch" service to check it. As a result we can see the following figure...

In this article the programs are designed to prevent the detection and cease running of malware were analyzed. It can be both separate "support" programs and "side" functional integrated in malicious program.

Lately any Internet user can become a victim of cyber criminals, even if he has installed an expensive anti-virus and firewall software with latest updates. When it is considered that the malicious scripts are created by special generators using different obfuscation techniques, it is evident that the probability to detect the malware by signature scanner is very low. And if the browser has a weak security policy, the malicious script will be launched on the user's computer. Such attack can be stopped only at the last stage, when a proactive anti-virus protection will block the execution of downloaded malware or a script.

In this article I would like to tell about removing malicious program's activity of consequences by antivirus. Users often write on the forums that not all effects of the payload were eliminated. And I would like to explain why it happens.
