Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a method, apparatus, electronic device, and storage medium for upgrading a virus database. Background Technology

[0002] With the widespread application of computer technology in all aspects of social life, viruses, like their byproducts, have followed suit. To ensure the network security of terminal devices, antivirus software needs to be installed. The detection performance of antivirus software relies on its virus database. The virus database is a collection of virus characteristics that allows terminal devices to quickly detect viruses based on these characteristics. Therefore, it is necessary to update the virus database periodically.

[0003] However, for standalone antivirus software, since there is no server deployed for centralized management and the terminal devices are located on a local area network and cannot connect to the internet, the virus database of standalone antivirus software cannot be updated in batches. That is, the latest virus database needs to be imported individually for each terminal device. When the number of terminal devices requiring virus database updates is large, the efficiency of this method will be significantly reduced.

[0004] Therefore, there is an urgent need for a method, device, electronic equipment, and storage medium for upgrading virus databases to solve the above-mentioned technical problems. Summary of the Invention

[0005] In order to enable batch upgrades of multiple terminal devices in a local area network, embodiments of this specification provide a method, apparatus, electronic device, and storage medium for upgrading a virus database.

[0006] Firstly, embodiments of this specification provide a method for upgrading a virus database, applied to a target terminal device deployed in a local area network, the method comprising:

[0007] In response to importing the virus definition update package, a broadcast message is sent to other terminal devices deployed on the local area network;

[0008] Based on the broadcast message, a target connection is established between the target terminal device and the other terminal devices.

[0009] Based on the type of the target connection, the virus database update package is sent to the other terminal devices.

[0010] In one possible design, the step of sending a broadcast message to other terminal devices deployed in the local area network in response to importing the virus definition update package includes:

[0011] In response to the import of the virus definition update package, the FTP setup software on the target terminal device is launched to set up the target terminal device as an FTP server;

[0012] The configured FTP address is broadcast as a message and sent to other terminal devices deployed in the local area network; wherein, the FTP address includes the IP address, username, password and absolute path of the target terminal device where the virus database update package is located.

[0013] In one possible design, sending the virus database update package to the other terminal devices based on the type of the target connection includes:

[0014] When the target connection type is FTP, receive and verify the username and password sent by the other terminal device;

[0015] After successful verification, in response to a download command sent by the other terminal device, the virus database update package is sent to the other terminal device.

[0016] In one possible design, the type of the target connection is a shared file type;

[0017] The response to importing the virus definition update package includes sending a broadcast message to other terminal devices deployed in the local area network, including:

[0018] In response to the import of the virus definition update package, the folder containing the virus definition update package is configured as a shared folder;

[0019] The absolute path of the shared folder and the IP address of the target terminal device are used as a broadcast message, and the broadcast message is sent to other terminal devices deployed in the local area network.

[0020] In one possible design, the target connection is of type TCP;

[0021] The response to importing the virus definition update package includes sending a broadcast message to other terminal devices deployed in the local area network, including:

[0022] In response to the import of the virus definition update package, a TCP port is created;

[0023] The TCP port, the IP address of the target terminal device, and the TCP connection method are used as broadcast messages, and the broadcast messages are sent to other terminal devices deployed in the local area network.

[0024] In one possible design, the target connection is of type UDP;

[0025] The response to importing the virus definition update package includes sending a broadcast message to other terminal devices deployed in the local area network, including:

[0026] In response to importing the virus definition update package, the IP address and UDP connection method of the target terminal device are broadcast as a broadcast message, and the broadcast message is sent to other terminal devices deployed in the local area network.

[0027] In one possible design, sending broadcast messages to other terminal devices deployed in the local area network includes:

[0028] Send a broadcast message to the broadcast listening port of other terminal devices deployed in the local area network; wherein the broadcast listening port is created after the antivirus software of the other terminal devices starts.

Therefore, this solution enables batch upgrading of multiple terminal devices in a LAN without a centrally managed server. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments in this specification clearer, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without creative effort are within the scope of protection of this specification.

[0041] Please refer to Figure 1 This specification provides a method for updating a virus database, applied to a target terminal device deployed in a local area network. The method includes:

[0042] Step 100: In response to importing the virus definition update package, send a broadcast message to other terminal devices deployed on the local area network;

[0043] Step 102: Based on the broadcast message, establish a target connection between the target terminal device and other terminal devices;

[0044] Step 104: Based on the type of the target connection, send the virus definition update package to other terminal devices.

[0045] In this embodiment, when importing the virus definition update package to the target terminal device, the target terminal device sends a broadcast message to other terminal devices deployed in the local area network. This broadcast message establishes a target connection between the target terminal device and the other terminal devices, allowing the virus definition update package to be sent to the other terminal devices based on the type of target connection. Therefore, the above solution can upgrade multiple terminal devices in a local area network in batches.

[0046] In one embodiment of this specification, the step of "sending a broadcast message to other terminal devices deployed in the local area network" may specifically include:

[0047] Send broadcast messages to the broadcast listening ports of other terminal devices deployed on the local area network; the broadcast listening ports are created after the antivirus software on the other terminal devices starts.

[0048] In this embodiment, by creating a broadcast listening port, other terminal devices can receive broadcast messages sent by the target terminal device, and the creation of the broadcast listening port depends on the startup of the antivirus software on the other terminal devices.

[0049] Since broadcasting is a one-way broadcast, it can use UDP broadcasting.

[0050] For example, when antivirus software on other terminal devices starts up, it creates a broadcast listening port 1. The target terminal device sends a broadcast message to the designated port 1 of all other terminal devices on the local area network, and the other terminal devices can then receive the corresponding message content. Of course, for other terminal devices that do not want to update their virus definitions, a toggle switch can be set up. Users can control this switch to prevent their port 1 from receiving broadcast messages, thus preventing them from downloading the corresponding virus definition update package from the target terminal device.

[0051] It should be noted that after receiving a broadcast message, the broadcast listening port of other terminal devices parses it, thereby determining what type of broadcast message it is (e.g., FTP, TCP, UDP, or shared file), and thus enabling the target terminal device and other terminal devices to establish what type of target connection.

[0052] The following section introduces four virus database update strategies.

[0053] The first method is to access an FTP server:

[0054] In one embodiment of this specification, step 100 may specifically include:

[0055] In response to the import of the virus definition update package, the FTP setup software on the target terminal device is launched to set up the target terminal device as an FTP server;

[0056] The configured FTP address is broadcast as a broadcast message and sent to other terminal devices deployed on the local area network; the FTP address includes the target terminal device's IP address, username, password, and the absolute path to the virus definition update package.

[0057] In this embodiment, by launching FTP setup software (such as FileZilla) on the target terminal device when importing the virus definition update package, the target terminal device is set up as an FTP server. The target terminal device can then send the configured FTP address to other terminal devices deployed on the local area network. To ensure secure access to the FTP server, the FTP address must include the target terminal device's IP address, username, password, and the absolute path to the virus definition update package.

[0058] In one embodiment of this specification, step 104 may specifically include:

[0059] When the target connection type is FTP, receive and verify the username and password sent by other terminal devices;

[0060] After successful verification, in response to download instructions sent by other terminal devices, the virus definition update package is sent to those other terminal devices.

[0061] In this embodiment, in order to enable other terminal devices to securely access the target terminal device, it is necessary to first verify the access of the other terminal devices, that is, to verify the username and password sent by the other terminal devices; only after the verification is successful can the target terminal device be downloaded by other terminal devices to download the virus database update package.

[0062] The second method is to access a shared folder:

[0063] In one embodiment of this specification, the target connection is of type shared file.

[0064] Step 100 may specifically include:

[0065] In response to importing virus definition update packages, configure the folder containing the virus definition update packages as a shared folder;

[0066] The absolute path of the shared folder and the IP address of the target terminal device are broadcast as a broadcast message, and the broadcast message is sent to other terminal devices deployed in the local area network.

[0067] In this embodiment, by configuring the folder containing the virus definition update package as a shared folder when importing it, the target terminal device can send the absolute path of the shared folder and its IP address to other terminal devices deployed on the local area network. Upon receiving the broadcast message, other terminal devices will access the target terminal device's shared folder and download the virus definition update package.

[0068] The third method is to use a TCP connection:

[0069] In one embodiment of this specification, the target connection type is TCP.

[0070] Step 100 may specifically include:

[0071] In response to the import of the virus definition update package, a TCP port is created;

[0072] The TCP port, the IP address of the target terminal device, and the TCP connection method are broadcast as a message, and the broadcast message is sent to other terminal devices deployed on the local area network.

[0073] In this embodiment, a TCP port is created on the target terminal device when importing the virus definition update package. Then, the target terminal device can send the TCP port, the IP address of the target terminal device, and the TCP connection method to other terminal devices deployed in the local area network.

[0074] Understandably, after the TCP three-way handshake, the target terminal device and other terminal devices establish a TCP connection. In this way, other terminal devices can send requests to the target terminal device to obtain virus definition update packages, and the target terminal device can send the virus definition update packages to other terminal devices via a socket; alternatively, after establishing a TCP connection, the target terminal device can directly send virus definition update packages to other terminal devices.

[0075] The fourth method is to use a UDP connection:

[0076] In one embodiment of this specification, the target connection type is UDP;

[0077] Step 100 may specifically include:

[0078] In response to the import of the virus definition update package, the target terminal device's IP address and UDP connection method are broadcast as a broadcast message, and the broadcast message is sent to other terminal devices deployed on the local area network.

[0079] In this embodiment, since UDP is a one-way connection, when importing the virus definition update package, the target terminal device directly sends its IP address and UDP connection method to other terminal devices deployed on the local area network. Thus, after establishing the UDP connection, the target terminal device can directly send the virus definition update package to other terminal devices.

[0080] In summary, the above technical solution solves the inefficient method of upgrading the virus database on a standalone antivirus software terminal, which requires each terminal to operate and upgrade independently. Instead, it uses a more efficient synchronous batch upgrade method to free up manpower and save time.
