What is a .NDB file?
The .NDB file extension stands for a ClamAV Extended Signature File. This type of file is specifically used by ClamAV, which is a free antivirus software that anyone can download and use to protect their computer from viruses and malware. The .NDB file contains important information that helps ClamAV recognize and deal with malware. This information is formatted in a specific way, listing the name of the malware, the type of file it targets, where it can be found within that file, and a unique sequence of characters (hexadecimal signature) that identifies the malware.
To open or use .NDB files, you would typically use the ClamAV program itself or other antivirus programs that are compatible with ClamAV's file formats, such as ClamWin or ClamXav. These programs use the .NDB files to update their database of known malware signatures. This means that when you scan your computer for viruses, the antivirus program checks the files on your computer against the list of malware signatures contained in the .NDB file to see if any of them match. If a match is found, the program can then take action to neutralize the threat.
In addition to the .NDB files, ClamAV also uses .CVD files, which are another type of file that contains virus definitions. However, the .NDB files are used for adding custom or extended signatures that might not yet be included in the .CVD files. This feature is particularly useful for advanced users or network administrators who want to add extra protection against specific threats that are relevant to their systems or networks.
In summary, .NDB files are a crucial part of the ClamAV antivirus program, allowing it to identify and protect against a wide range of malware by containing detailed information about each threat. These files can be opened and used by ClamAV and compatible programs like ClamWin and ClamXav to ensure your computer stays safe from harmful software.
