Live a computer virus, it is known that everyone knows that some people who have eaten a virus are a bit a little talk about the feelings of tiger. In fact, no matter whether it is an individual, the hazard of the virus is inevitable, especially for Windows users, there may be more viruses, and the "shock wave" virus in front of the world has caused huge losses around the world. It is actually a virus for Windows, and the operating system such as Linux is invalid. It used to have a point of view. There is no virus on Linux. Nice in the early days of Linux did not find viruses, and because Linux as a scientific design of the operating system in permission control, it is very difficult to develop viruses on Linux, but with technology The development has also begun to have some viruses for Linux. For example, Linux / Bliss is a virus for infection with the ELF file on Linux, and there have been some worms for individual Linux service bugs. However, there is also a anti-virus software on Linux, such as this article to introduce Antivir.
Antivir can scan the latest Linux virus. It is a commercial product. You can purchase it to get regular updates of the virus definition library, which has different platforms, for users of the Linux platform, even if you don't spend money to buy usable. This is a good news for personal users, but for corporate users, if you feel easy to use, it is recommended to purchase. Antivir's vendor website is http://www.hbedv.com.

3. After registering a KEY installation, go to http://www.antivir.de/ to apply for a key, otherwise Antivir can only run in Demo. Currently (August 2003) The URL is http://www.antivir.de/order/privreg/order_e.htm ,key will send it to the Email mailbox filled in when you apply, after completing the registration page, about a few minutes After that, you will receive two attachments hbedv.key and lib_info.txt, and then copy HDEDV.Key to the / usr / lib / antivir directory:

It can be noted: First: The system has the correct key: Antivir license: 1001049056 for Terry, Shanghai second: The system discovers four infected files, and lists the file names and other information, the system is more than 25 minutes. After sweeping 4,7003 files, you give a simple scan result Antivir's other parameters. Please query the following command when needed: # Antivir --help5. Install the graphical interface You may think that the command line is not very friendly, so Here, a graphical interface that matches Antivir - TKANTIVIR. Tkantivir is written with Tcl / TK, which can be run under any x-windows environment, such as KDE or GNOME, etc.
Download http://www.sebastian-geiges.de/tkantivir/ Because tkantivir is developed by Tkantivir, be careful not to download the German version while downloading, I got a German version. The download address of the English version directly here is as follows: http://www.sebastian-geiges.de/tkantivir/tkantivire-1.41-1.i386.rpm Installation Since the download is the RPM package, the installation process is very simple, the installation command As follows: rpm -ivh tkantivire-1.41-1.i386.rpm
Then create a directory to store log files # MKDIR / USR / LIB / ANTIVIR / LOG
Run # startX (enter KDE or GNOME) # TKANTIVIR (running command in Konsole) The first time, there will be a prompt window that pops up (Figure 1):
Figure one
The window appears after "OK" (Figure 2):
Figure 2 Create a directory created before the Path for log file: / usr / lib / antivir / log, then "OK" is officially running (Figure 3):
Figure three
The following is the main window of tkantivir (Figure 4)
Figure 4 Enter the directory you want to scan in Path, which is entered / mykms. Then consider other sub-options to control the conditions of the scan. After selecting it, press the "Magnifying Glass" icon on the left, you will pop up another window, please confirm (see Figure 5): Figure 5
After the "YES" is confirmed, a window displays the specific situation of the scan, as shown below (Figure 6):
Figure 6
With this graphical interface, I believe that people who have used other Windows under virus software is easy to familiarize. This specially reminds Linux users, do not want to pay attention to computer viruses under Linux. Although the virus under Linux is far from Windows, the virus is also very dangerous to system security for Linux. There are also many viral solutions under Linux, but also to remove Linux viruses, but also sweep away Windows viruses, which is helpful for users who use Linux to do file servers or users who have multiple operating systems.
