Hackers not only attack big websites and corporations, but also individual computers in homes or businesses. Hackers can do damage and use your computer in many ways. As a start to many of hacker's nefarious deeds, they need access to your computer. One common way they gain it is through the use of a program called SubSeven. Before the hackers can use the program, they have to get it on your computer. You can unwittingly get a copy of SubSeven on your computer in many different waysfor example, you can open a file in an email message and it can be installed to your computer without you realizing it, or you can be sent the program when you use Internet's IRC chat protocol.
