A computer virus is an executable program. Depending on the nature of a virus, it can damage the contents of your hard disk cause and / or interfere with the normal functioning of your computer.
By definition, a virus program is able to self-replicate. This means that the virus multiplied in a computer by making copies of itself. Repetition is intentional, this is part of the virus. In most cases, if a virus file is executed or copied to another computer, this computer will be "infected" by this virus.
A virus can be inserted into a computer system with a software program. For Internet users, the threat comes from downloading files via FTP (File Transfer Protocol), or references e-mail attachments. (Please refer to our website over the handling of e-mail File Attachments for more information.)
When a virus is introduced into a computer system, it can be self-attached, or sometimes even to replace an existing program . So when the user runs the program in question, is the virus running. This usually happens without the user being aware of it. A virus program contains commands a kind of "event" that affects the infected computer to start. Each virus has a unique opportunity to connect with.
These events and their consequences can range from harmless to devastating. For example, an annoying message on the computer screen. Reduced memory or disk space. Changing data. Overwrite or damaged. Hard drive erased.
