Computers under Attack

Computers under Attack

    There are three groups of virus causing troubles for any computer users. First of all, a Trojan Horse. It is planned to obtain credits card details or bank passwords. In addition, Spyware. This kind of virus saves the fact about the computer’s owner. Finally, Spam  is used to cheat people and to get money from them.
