Update
A new version of a software or hardware product designed to replace an older version of the same product. In addition, the installation routines for updates often check to make sure that an older version is already installed on your computer; if not, you cannot install the update.
BitDefender has it's own update module that allows you to manually check for updates, or let it automatically update the product.
Virus
A program or piece of code that is loaded onto your computer without your knowledge and runs against your will. Most viruses can also replicate themselves. All computer viruses are manmade. A simple virus that can copy itself over and over again is relatively easy to produce. Even such a simple virus is dangerous because it will quickly use all available memory and bring the system to a halt. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems.
Virus definition
The binary pattern of a virus, used by the antivirus program to detect and eliminate the virus.
Worm
A program that propagates itself over a network, reproducing itself as it goes. It cannot attach itself to other programs.
