The virus hoax

The hoax is a false email message which warns the recipient of a virus. The message usually serves as a chain e-mail that tells the recipient to send it to everyone you know.
Most hoaxes are easily identified by the fact that they say the virus will make damage in your PC.
Virus hoaxes are usually harmless and just than annoy people. They just know it's a hoax or waste the time of people who forward the message. However there are so many hoaxes which just call people’s attention to if they delete the program, the computer will have damaged.
Hoaxes are not the same as computer pranks. Computer prank is a program that performs unwanted and annoying actions on a computer, like randomly move the mouse.
The anti-virus specialists advice: we should delete virus hoaxes instead of forwarding them. For example, McAfee says: "We are advising users who receive the email to delete it and DO NOT pass it on as this is how an email HOAX propagates.”

Computer attackers

Computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. The original may modify the copies or the copies may modify themselves, as occurs in a metamorphic virus. It can spread from one computer to another by help of network connection or carrying it on a removable medium such as floppy disk, CD, DVD, USB drive or by the Internet. But viruses are not equal to computer worms and Trojan horses. A worm can spread itself to other computers without being transferred as a part of a host, and a Trojan horse is a file that appears harmless until executed.
Many PCs are now connected to the Internet and/or to local area networks. Today's viruses may also take advantage of network services (World Wide Web, e-mail, file sharing systems). Some viruses are programmed to damage the computer by damaging programs, deleting files, or reformatting the hard disk. Others are harmless, but simply replicate themselves and make their presence known by presenting text, video, or audio messages. Although these viruses are not dangerous, they can create problems for the computer user. As a result they often cause erratic behavior and can result in system crashes. In addition, many viruses are bug-ridden, and these bugs may lead to system crashes and data loss.

Save your data!

Nowadays we keep almost every data on our PC. Our e-mails, wedding photos, family videos or the photos of your baby’s first birthday, etc… You never know who will break into your home, steal the computer and in this way you lose your memories.

For this reason, it’s very important to save your data on another media source. But not just private data, business data, too. In big companies it is done automatically but in little ones it is not such general practice. Therefore, you have to keep in mind data saving. Maybe you say: “I have a very serious alarm system. Nobody can break into it!” But you are not only threatened by criminals. Anything can happen such as a blackout or a virus or something which can destroy your database. Ahead of damage you have to save everything on a CD/DVD or some other form such as an external harddrive.
