Hello friends, I own a cyber of my own that has some 20 odd computers in it. Recently, all my computers were attacked with some viruses and all my computer were badly affected due to it. Also, I came to know that the there was also some kind of trojan horse program running in all my computers that has taken all the information that was there. Clearly, too many people comes over to my cyber either to chat,surf and to do their personal things so the amount of data that the hackers might have stolen is not known. Also, since they now have my IP address they can now use this to attack other computers. Although I have removed all my pcs and reseted the server but still I am afraid if the hackers carry on their further attacks. So please can any one tell how this happens and how can it be avoided.
