Many of my friends are infected with viruses and asked me for help. In order to solve the problem more conveniently and more specifically, I have selected some free anti-virus tools to make a very practical anti-virus flash disk. After plugging in the flash disk, a self-starting program will appear. Depending on the situation, you can select the appropriate tool to help the system "detoxify. Do you want to do one? Next, let's take a look at DIY.
Start Anti-Virus
Generally, anti-virus flash disks are used to create anti-virus flash disks. What should I do if no anti-virus software is installed in the system?
In fact, some vendors provide free DOS anti-virus programs. Dr. An's V3 + Neo is one of them. Its biggest advantage is its small size and fast updating of the virus database. Dr. an V3 + Neo: http://www.ahn.com.cn/download/v3neomain.asp.
First, use the formatting tool in the flash drive disc or USBoot to create a boot flash disk. In the list on the USBoot interface, select the flash disk (figure 1 ).
Select the ZIP working mode and click Start. After the configuration is complete, copy the required Startup File and the doctoral DOS version to the flash drive. In this case, v3.exeis the scanning program used by DOS. update.txt provides a list of latest viruses to be detected after upgrade. *. v3d is the antivirus engine file.
Boot your computer into BIOS, turn on the Advanced BIOS Features option, and set "First Boot Device" to USB-ZIP Boot. Save settings and restart to enable Flash Drive startup. Go to the PhDs directory and run the dig v3.exe C:/a/s/u/l: e command. When a virus is detected, the program will notify the user and automatically clear it. However, if a virus cannot be detected, the program does not provide many processing methods, such as "whether to delete files", and does not have functions such as renaming or isolating viruses (figure 2 ).
Dr. an updates the virus database once every workday. After downloading the file again, He extracts all the *. v3d files and overwrites the original files.
In addition, Trend Micro also provides a free DOS antivirus program, but the virus database is large, which is http://www.trendmicro.com/download/zh-cn/emg-disk.asp.
Comprehensive Anti-Virus
Although it is convenient to use a flash drive to copy files, it also increases the risk of virus transmission. If no antivirus software is installed in the other system, it is more difficult to ensure data security. Fortunately, McAfee provides us with a free SuperDAT antivirus program, which consists of a virus database and scan engine. As long as it is put into a flash disk, it can not only detect computer files, the virus can also be rejected outside the "disk.
Extract files
After downloading SuperDAT, go to the folder where it is located in command line mode, and run "sdat ***. exe/eexe to extract the files in superdatav. This folder will add more files and package scan for the virus database scan.datav main program scan.exe.
Add Interface
SuperDAT is anti-virus in command line mode and has many parameters, which is inconvenient to use. We can use PeBuilder to add a graphic interface for McAfee. Download and decompress PeBuilder, open the pluginmcafee directory, and copy the extracted file here. Run the plug-in program scangui.exe to display the main software interface (Figure 3 ).
Anti-Virus
Click "..." under "What to scan" "button, select the directory to be scanned, select Scan inside archive files (Scan compressed package), Scan subdirectories (Scan subdirectory), Clean viruses (clear virus) and other options, click "Scan" to start scanning.
Quickly detects and removes popular viruses
When a friend accesses the Internet, he often encounters Trojans, worms, and other popular viruses. It is a good choice to use the kill-killing tool with high speed. Most of the kill tools are single executable files, which can be directly copied to the flash drive.
Common exclusive tools can only scan for a specific type of virus, avast! Virus Cleaner can quickly detect dozens of worms and their latest variants, such as shock waves and shock waves, at http://www.skycn.com/soft/15293.html. It does not need to be installed. You can click Start scanning to scan the memory and disk (figure 4 ).
The infected files are automatically repaired. Click the "About" button to view the list of viruses that can be detected by the software.
I like to use 3721 Anti-Spyware expert (http://download.3721.com/fjdzj/fjdzj.exe) to deal with Trojans ). Install it on the hard disk, and copy the files in the installation directory to the flash drive to run.
There are many exclusive killing tools that you can choose based on your preferences.
Auto-Start Menu
In order to be more comfortable with the virus, the author uses the AutoRunPro Chinese edition to create a self-starting program for the flash drive, which can quickly start the anti-virus program in the flash drive, and can add images, buttons, videos and other elements to the interface.
Click "File> wizard" in the menu, click "select", set the directory for saving the self-starting program, and store all the anti-virus tools in this directory. Right-click the blue form, select "form and pop-up properties", and set the title and background color of the form.
Click the "Add button" icon in the toolbar. A button is displayed in the form. enter the name of the button in the "title" of "Object checker" on the left (figure 5 ).
Then add the button icon in the "bitmap", but the Icon size should not be too large.
Select action. In "click action", select "Open File". The software also provides "Send email", "exit", "Browse CD", and other actions. Set the main program of the corresponding anti-virus tool in "file, URL or Email", click "Add Tag", and enter instructions in "title, to facilitate use by other friends.
Save and test. Click "File> Save and test" to see the effect. Finally, copy all the files saved in the self-starting program directory to the root directory of the flash drive. After the flash disk is inserted, the startup interface is displayed. You can click the button to directly run the program.
This anti-virus flash disk is very simple to use and is easy to carry. You can select the corresponding anti-virus tool based on your actual needs and the size of the flash disk.
