The details of the virus and antivirus software check are as follows

to my blog.

Kaspersky Internet Security under the best antivirus

and the best firewall ZoneAlarm Pro and the best Trojan killer software Ewido Plus

Upgrade first, then scan for viruses in safe mode!!

The firewall zonealarm can be installed after the antivirus.

If you are hit by a powerful virus, you need to enter safe mode to detect and kill.

Enter Safe Mode in WindowsXP Environment:

1. After the BIOS is loaded on the computer, quickly press the F8 key and select "Safe Mode" in the Windows XP Advanced Options Menu that appears;

2. If there is a multi-system boot, when selecting WindowsXP to start, when pressing the Enter key, you should quickly press the F8 key (it is best to operate with two hands), and select "Safe Mode" in the WindowsXP advanced options menu that appears.

Another way.

1. In the Windows environment, click the "Start" menu, and then click "Run";

2. Enter msconfig and click the "OK" button.

3. Click on the "Tab";

4. Choose"/safenoot"；

5. Then click the "OK" button to save and exit, and restart the computer;

6. The Windows XP advanced options menu that appears after rebooting is similar to that of Windows 2000, select "Safe Mode";

7. If you want to cancel the "Advanced Options Menu", repeat the above steps 1-5, the difference is that step 4 deselects"/safenoot

According to the situation you said that you are a PE virus under Windows , the type of behavior Trojan under Windows , he can connect automatically**.

b This question is a bit old, right?,It should be a question from the domestic exam.。

10 years ago, I chose B

All four of these are true now.

b Now viruses can destroy hardware.

It is said to be b

The legendary hardware-destroying virus CIH is just a change to the BIOS.

There are only a few types of computer viruses. This one is wrong.

A computer virus refers to a set of computer instructions that are compiled or inserted into a computer program to destroy computer functions or data, affect the normal use of a computer, and can replicate itself.

Computer viruses are slow-spreading, hidden, infectious, latent, excitable, expressive or destructive. Calculate the life cycle of the virus: development period, infectious period, incubation period, attack period, discovery period, digestion period, and extinction period.

Computer viruses have their own transmission patterns and different transmission paths. The main function of the computer itself is its own replication and propagation, which means that the propagation of computer viruses is very easy, and the virus can usually be spread in an environment where data can be exchanged.

b Computer viruses do not damage computer hardware systems.

Of the following statements about computer viruses, (a) is correct.

b) A computer virus is a program that has been corrupted.

c) Anti-virus software must be upgraded as new viruses emerge to improve the function of checking and killing viruses d) Computers infected with computer viruses are immune to the virusCorrect answer: a

Analysis: Anti-virus software can check and kill viruses, but it cannot check and kill all viruses. New computer viruses may emerge all the time, and anti-virus software is created with them, and anti-virus software usually lags behind the emergence of new computer viruses.

Anti-virus software often lags behind the emergence of new computer viruses.

Antivirus software, also known as antivirus software or antivirus software, is a class of software used to eliminate computer threats such as computer viruses, Trojan horses, and malware. Antivirus software usually integrates monitoring and identification, virus scanning and removal, automatic upgrade, active defense and other functions, and some antivirus software also has functions such as data recovery, prevention of hacker intrusion, network traffic control, etc.

It is an important part of the computer defense system (including anti-virus software, firewalls, Trojan horse and malware detection programs, intrusion prevention systems, etc.). Antivirus software is a program tool that can remove viruses, Trojan horses and all other programs that are known to be harmful to your computer**.

"Anti-virus software" was given by the older generation of anti-virus software manufacturers in China, and later became known as "anti-virus software", "security protection software" or "security software" due to its integration with the world's anti-virus industry. Internet Security Suite with integrated firewall, All-in-One Security Suite, and other types of software used to eliminate computer viruses, Trojan horses, and malware.

All fall under the category of antivirus software. Anti-virus software is tasked with monitoring and scanning disks in real-time. Some anti-virus software adds drivers to the system and starts with the operating system.

Most antiviruses also have firewalls. How antivirus software is monitored in real-time varies from software to software.
