Computer viruses, and software, also by the code for a component of. The virus, and software is not the same place, the software is used to help people learn to carry out normal day-to-day use, the virus is a certain purpose or attempt to use malicious code on computer systems, procedures, as well as some damage to the network.
in our peacetime use of the process, understanding that if the virus will not be so nervous, in fact, the virus is only for a procedure to do a good job as long as the appropriate protective measures to protect their computers, pay attention to the use of computers in general Would not in the virus.
on the virus, there is a problem, it is horse. Although the virus is the same, but the type of viruses and Trojan horses are different. The general nature of the virus is a malicious, and the horse is to be hidden in the computer, hidden in the background or task orders.
usually in the virus, there will be a lot of the symptoms, so we will be here in the main list for you to judge and to deal with.
(1) Windows unusual error message
Windows error message is a Windows system to provide a new feature to the user and Microsoft to provide wrong information, user-friendly. However, the operating system itself, in addition to the closure of the user or program error, an error will not be reported. As a result, this may be in the virus. In 2004, as well as the shock waves virus Sasser virus, it is using the process to shut down the system, and then prompted an error, warning users of 1 minute countdown shutdown.
control: the virus, usually a new virus, according to the number of new vulnerabilities to spread, so generally the use of Zhuanshagongju. At the same time, these viruses spread through the network, use a firewall to shield the corresponding port visit and the results will be even better. End killing drugs, a good firewall settings, also need to install the systems patches.
(2) speed decreased, as well as to reduce the amount of memory, virtual memory or memory
computer when running under normal circumstances, it is important to run the software does not take up too much resources, will not reduce the rate of. If the speed is reduced, can view the process, first of all look at the occupancy rate of CPU and memory usage, and then the process of checking to see if the user is in the process of resource-intensive process which is not normal. If the virtual memory may be occupied by the virus, or it may be improper.
control: this type of virus is usually very resource-intensive, so easy to find the worm. The discovery of the virus, the virus process, as well as close-virus program, and then check the use of anti-virus software, if not killing, the Treasury proposed to upgrade the virus.
(3) procedures to run all of a sudden abnormal death
computer programs, if not designed correctly, can open the normal closed. However, if the virus is damaged, many of the procedures required documents will not use it, there may be a lock. IE, as well as software such as QQ software, often on an error.
prevention and treatment: procedural error, the installation program can use the CD-ROM to install or repair coverage, and if the virus still exists, still want to use antivirus software to check.
(4) file size
change is the use of a computer virus in some of the executable files, and executable bundle, and then run the program when the two run together. The kind of executable file only drawback is that the file size will change in the use of normal time when special attention should be paid.
prevention and treatment: anti-virus software for such an effective document, the most important thing is normally open to control the virus at any time to run the software on the monitor.
(5) abnormal operation
prompted to run the software, in addition to the normal tips, no other way of reminding. The virus could have run the infected software or files, so that users can not use normal.
control: software or procedures have been infected, it is not normal, it is necessary to check the use of anti-virus software, uninstall and then reinstall the software later.
(6) drive the same content
there is a virus that is devoted to the hard disk to amend the guidance letter, and then modify the contents of the hard disk into the same content, so users can not use.
control: this type of virus is rarely met, such as viruses need to revise the guidance of the hard disk, so they need access to high, and antivirus software at the same time such application filtering and detection.
(7) reboot the system can not find the hard disk and on the same
a guide belonging to the same virus, but more than that of a virus infection on the location of a deeper, it can cause the user can not boot.
prevention and treatment: recommendations remain open to monitor the virus, such virus at the same time the need for DOS antivirus software because of the need for guidance from the DOS, visit the area, as well as antivirus.
(8) system can not boot the system, as well as the slow start
start the system, the need to load and start-up software as well as a number of open files, and the virus is the use of this system in the start-up items, or system configuration Documents in the start-up.
control: regular inspections to start system configuration files or documents to start the project, whether there is a non-system startup files, and in the process to check whether there purpose do not know the procedure.
(9) browser to visit the Web site
computer in the network access, open the browser, often found in the home can be changed. Moreover, to visit the home pages of most of the money to click on individual sites or site is very healthy.
prevention and treatment: If the restoration of the home page is not very familiar with the proposal to install Internet Assistant software, and so on, so that the browser will carry out comprehensive protection, but also to reduce the malicious code attacks.
(10) mobile mouse for no reason
mouse position is also targeted by the procedure, so the virus can also define the location of the mouse, the mouse can tamper with full-screen, or can not be accurate positioning.
control: this type of virus is not harmful, mischievous belong to the category of viruses, such viruses as long as normal in the regular upgrading of antivirus software, at the same time pay attention to the use of software, the virus will not be in this.
(11) QQ tail
OICQ software on the network is a popular chat tool, referred to as the QQ. QQ tail of the virus, when the user opens a message window QQ, the virus automatically to the text of the message text input box, and then ranged up on the user response to the issued.
prevention and treatment: the use of QQ tail virus Zhuanshagongju
(12) Auto
computer network connecting the network connection is generally passive connections are triggered by the user to, and the virus in order to access the network, must take the initiative to connect, so some Virus contains a network connection automatically.
control: disconnect the network, and then killing the virus.
(13) Modem and hard work of the mad light flash
light work of the Modem is used to indicate the cat or the hard work of the state, the normal use, the indicator light is flashing it often. If this happens, is run by checking whether the procedures take up too many system resources.
prevention and treatment: same as the network and automatically connect the need to disconnect the network, and then re-check procedures and processes, use a firewall to check for unauthorized network access software.
(14) can not use the registry, some registry keys have been shielded
equivalent to the core of the operating system, database, if the hot keys and registry were shielded, in a virus, not on the repair.
prevention and treatment: a rabbit can use the super-magician or optimize the Windows registry for the restoration of the master, but also the hot key to the lifting of the shield.
(15) in the network automatically dropped
access the network, under normal circumstances automatically dropped, and some viruses take up special systems or network resources to close the connection, causing inconvenience to users.
prevention and treatment: the use of a stable network connection, the same need to check the use of antivirus software.
over several public listed common characteristics of the virus, a common virus and there are other cases where only some examples of the representative. In fact, the virus is not a terrorist. HIV is only for a procedure, as long as we are conscious efforts in this area to guard against is to deal with all kinds of viruses.
First of all, antivirus software and firewall protection of computer security as long as the operating system properly set up, as well as the use of patches in a timely manner, can resist the overwhelming majority of network attacks. Antivirus software is also used to pay special attention to, because the virus constantly changes, and even more varieties, so we should pay attention to up-to-date anti-virus software library. As for the firewall is the network in order to prevent the virus. During his visit to a computer network by the time to visit the port, as long as it does not need to use the port closed, we can achieve a certain degree of security purposes.
then there are the security system software. Trojan nemesis, Super Rabbit, and other software wizard, are commonly used to protect computer software, the system can be certain of finishing, as well as the discovery of the virus, can be modified in certain settings.
finally set up its own system. The virus checks, the system itself can do a lot of, for example, from the process of view, the use of netstat command in the DOS command under the command checks the network. In addition, the most important computer registry, is also important because many of the registration system are preserved in the registry. In dealing with these outside, the security system itself is also very important. The operating system is not safe, the system is installed, users will find a lot of loopholes, the operating system manufacturers will in time provide some loopholes in the system, patch or patches. As a result, in the normal use of the process, the need for timely attention to some of the loopholes in the system, to prevent violations of the virus.
virus, never a topic of the virus is now making more and more advanced technology, and anti-virus software is also active with the protection of our computer resources. As long as we learned how to correct some of the computer operations related to the use of protective measures for the defense of the virus, we can do
