1. Ghost and shadow virus As it is difficult to solve the ghost and shadow virus by formatting and reinstalling the system, it is given the name of "no Ghost. Currently, the ghost and shadow viruses are mainly transmitted by webpage Trojans. Kingsoft cloud security system analyzes the download frequency of the malware and analyzes the website traffic of the virus, the Daily Download volume for evaluating the virus is about 2-3 million. After being poi

Broadband also gives us a faster Internet access speed, but also brings convenience to the spread of viruses. How to prevent viruses becomes a crucial issue. We can kill viruses in the following ways. Step 1: Make sure you have a strong password for the administrator. According to the data, many people only use images conveniently when installing Windows 2000 or

No virus or Trojan exists in the system and cannot be completely isolated from the process. Even if the hidden technology is used, it can still find clues from the process. Therefore, viewing active processes in the system is the most direct method for detecting viruses and Trojans. However, there are so many processes running simultaneously in the system, which are normal system processes and Trojan processes, what role does a system process that is

The preparation of the virus is a kind of advanced technology, the real virus generally have: infectious, hidden (also known as latent), destructive. Now there are many kinds of viruses, such as the usual infection of executable files of viruses, macro viruses and so on. But the original, most destructive viruses are

With the popularization of computers and the development of information technology, the word "computer virus" is no longer unfamiliar to everyone. Nowadays, computer viruses are emerging one after another, even the vast number of computer users have almost reached the level of "Talking about changing the color of drugs

In general, in an operating system, a process is an activity that runs a program on a computer to execute an instance. When we run a program instance, a process is started. The Unix operating system assigns a unique process identification number to each process. Each process has a UID assigned to all processes called by that user. Each process has a priority. The scheduler uses it to determine the next running process. This is what we call the managem

Custom Controls disguise "viruses" In the past few days, cainiao D has been engaged in custom controls (all Manager errors). A few days ago, the loading errors in the design field were rather miserable. Fortunately, a solution was found. Just today, a problem that my colleague accidentally mentioned has left cainiao D hard-working for a day. "Do you know? When a custom control is dragged to the designer interface, some methods of the custom control ar

nothing for most hard drives. We have two backup systems for viruses. After poisoning, we use the ghost2 file to restore them. After restoring the system, the software after the first backup is still in use. No installation is required, saving a lot of trouble. If it is still toxic after restoration, it indicates that the virus has been backed up to the ghost2 file and it is useless. If it is deleted, restoring it with the ghost1 file will solve the

has happened, and perhaps the effect is already obvious." If nothing happens, turn off the designer interface and open it again, this time it will be done.If you write the code to kill the idea too strong, the computer has been broken, hehe, his own death can not blame others. And then imagine, define a custom control, such as the method injection attack (open a thread, peeping the data on the hard disk and so on, you know), confuse the code with the

, mutual love is an agreement, and mutual observation is true love. The MAC address is the unique identifier of the network card. Generally, it cannot be modified at will. Any network card has a MAC address with a length of 48 bits, at the beginning, this address was burned in by the NIC manufacturer. Theoretically, the MAC address is globally unique and will not cause any conflict. However, due to the special nature of the operating system, we can modify some parameters so that the MAC address

One is to remove the virus program code from the infected file (for example, if a 10 K file is infected with a 2 K Virus and becomes 12 K, restore to a normal file of 10 KB). This is called clearing. 1. Why can't some viruses be cleared (not running) and can only be isolated but not cleared? The so-called antivirus software has two cases. One is to remove the virus program code from the infected file (for example, if a 10 K file is infected with a 2 K

prompts the infected user to spend money on disaster recovery. It can be said that the second-generation trojan has the transmission characteristics (though through the traditional delivery mode ). Third-generation Trojan: Network Communication Trojan With the popularity of the Internet, this generation of Trojan horse features both disguise and spread, and combined with TCP/IP network technology spread everywhere. At the same time, he has new features: 1. added the "backdoor" function. A backd
