With the popularity of the network, most anti-virus software uses online upgrades to update programs and virus databases. However, if the system encounters a problem and you need to reinstall anti-virus software, you must upgrade the Internet again, which is indeed time-consuming and labor-consuming. After my exploration, I have summarized several methods for backing up and upgrading the virus database of the most commonly used anti-virus software. This method is also effective for most previous versions.
KV antivirus king
After the "smart upgrade" of KV antivirus King is upgraded online, all the upgrade files are stored in the "Temp" directory of the installation directory. We can completely back up these upgrade files to other partitions. Reinstall the KV antivirus queen, go to "Tools> Settings> Upgrade", select "upgrade from Lan", select the directory where the upgrade file is located, and click "upgrade now.
Kingsoft drug overlord 6

Norton AntiVirus
After using the LiveUpdate of Norton AntiVirus to upgrade the virus database online, open the "system drive letter Program FilesCommon FilesSymantec SharedVirusDefs" Directory, which contains several folders named by date, for example, "0216.023" and "0218.021", these folders store the update files downloaded during each online upgrade and back up all the files in the latest folder. After the AntiVirus is reinstalled, copy the backup files to the "system drive letter Program FilesCommon FilesSymantec SharedVirusDefsincoming" directory and restart the firewall.
The backup and recovery methods for online file upgrade for other anti-virus software are similar to those above. If you are interested, refer
