Ways to spread viruses

For a virus or a similar program should not impact you should be able to spread from one machine to another. They are designed to provide access to parts of the computer for allowing communication with other computers. Below is a discussion of some of the most common methods.

Boot infectors

Every hard disk (hard disk, floppy disk, CD, DVD) contains a boot sector, be it a floppy boot o. If a computer is turned on, it looksStartup information. If the computer finds a disk with boot information, you read that information and uses it to successfully start the computer. If for some reason, the boat is infected with a virus information, the virus is active and, possibly, drive the computer is transferred to the difficult (if the infection to a CD for example).

Once the code boot disk with a viral infection, the memory must be loaded into the computer every time you start yourComputer. From memory the boot virus can travel in any and every hard disk that is stored on your computer. This is how the infection spreads.

Most boot virus on your system for a long time without any problems, just existing there, to spread itself. Often, these viruses are designed for their bad behavior at a given time (Halloween for example). There are some nasty boot virus, the boat can destroy the information or a full format of the hard diskDrive right after entering a computer.

Program infectors

When the infected application is executed the virus is activated and loaded into memory. While the virus in memory, a new program file, you can be infected. This means that there are multiple applications on your system that are infected. multiple infections are very common and will certainly cause problems to the system.

The program files can work without problems for some timebut in the end you will have problems or multiple infection brings the entire computer system. The data of the production schedule can be the first sign of infection, such as saving files without proper names, or saved with incorrect or incomplete data.

Viruses of this type are often designed to look for programs that information between the users / computers such as e-mail applications, screen saver, share Office document macro and self-extracting compressed files.

FromE-mail attachments

The files that can be sent in an e-mail - many of the most dangerous viruses are spread primarily through e-mail attachments. In such cases, the user of an infected computer is unknowingly infected file to submit an e-mail and send e-mail to a friend or colleague. If the e-mails received, the virus is launched when the attachment is opened, in order to infect a new computer. The e-mail messages with animations, automated greeting cards,Jokes, photos, spreadsheets, and document files have all been documented to contain files for viruses.

Increasingly these days, mass mailing email worms / viruses are released. These attacks will automatically scan your computer files for all e-mail that can find and then used to send your application by e-mail automatically sending infected messages to any e-mail to any file on your computer ( not only e-mail files) found.

It 'important to be aware ofE-mail pops up, check for viruses. could also have e-mails from friends and relatives if the person is a virus that your computer is infected. Here's an anti-virus software would be really useful to determine if a virus in an incoming message.
