The state of a virus when two independent researchers identify it in circulation within a one-year period. Approximately 450 viruses exist in the wild at any given time.
Industry:Internet
The Internet standard that matches names such as mcafee. Com to the IP address that routes packets to an Internet-connected computer.
Industry:Internet
A type of program containing instructions that a host application interprets and executes. Script instructions are usually expressed using the application’s rules and syntax combined with simple control structures. Examples are JavaScript and VBScript, which some web browsers can execute.
Industry:Internet
An evasion technique that allows a virus to avoid standard interfaces so it can infect files and go unnoticed by a behavior blocker. Tunneling viruses try to intercept the actions before the anti-virus software can detect the malicious code. One technique used by attackers is tunneling malicious communications through the standard port of another application (e.g., port 80 for HTTP) to avoid firewalls.
Industry:Internet
A false negative error occurs when anti-virus software fails to indicate that an infected file is infected. False negatives are more serious than false positives, although both are undesirable. False negatives are more common with anti-virus software because the software may miss a new or heavily modified virus.
Industry:Internet
A virus that overwrites files with its own viral code, destroying the original. There is no way to recover the data from such an infection except to retrieve the files from backups.
Industry:Internet
A system that distributes alert notifications to multiple network users. McAfee Alert Manager is one example. Anti-virus software (such as McAfee VirusScan) generates alert messages that are saved to a shared folder on a server. Alert Manager sends notifications to users from that folder. When users update the contents of the shared folder, Alert Manager sends new alert notifications using such user-configurable alert methods as email messages to handheld devices. When users receive alerts from the network intrusion prevention system, they can analyze correlation through drill-downs and then generate reports.
Industry:Internet
A type of process that is considered to have a lower possibility of being infected or accessing infected files. Examples include backing up software or code compiler and linker processes.
Industry:Internet
The size, in bytes, of the viral code inserted into a program by the virus. If this is a worm or Trojan, the length represents the size of the file.
Industry:Internet
Software or a device that monitors network traffic and prevents attacks on a network or system. McAfee Network Security Platform (formerly McAfee IntruShield) is one example.
