注意事項
Using that editor on one of the organization's machines causes the virus to spread from the editor to one of the progarams stored on the organization's machine,perhaps to a spreadsheet program.
因此在機構中的任一臺計算機上對編輯程序的使用，都會導致病毒從編輯程序傳播到該機構計算機內所存儲的某個程序上，也許是傳播到了一個電子表格程序上。
When an employee uses that spreadsheet subsequently, the virus can be spread to another progarm.
后來，當某個雇員使用這個電子表格程序時，病毒就又可能傳播到另一個程序上。
perhaps to a directory listing progam that the employee keeps on the same floppy disk as the spreadsheet data files.
也許是傳播到了另一個由該雇員保存的與電子表格程序存儲在同一個軟盤上的目錄列表程序上。
The listing program is then infected.
于是這個列表程序也就染上了病毒，
and the infection can be spread to other computers to which this floppy disk is taken.
而且這種感染又可以傳播到使用過這張軟盤的其它一些計算機上。
If the employee's computer is connected to the organization's network.
如果雇員的個人計算機與該機構的網絡相連，
the employee may send the listing program to another user over the network.
那么，雇員就可以把這個列表程序傳送給網絡上的另一位用戶。
In either case, the virus can spread to more users, and more machines, via floppy disks or networks.
不管是哪一種情況，通過軟盤或網絡，病毒就會傳播給更多的用戶和更多的計算機上。
Each copy of the virus can make multiple copies of itself and can infect any program to which it has access.
病毒的每一次復制，就會導致病毒本身的多次復制，并且使它曾訪問過的任一程序受到感染。
As a result , the virus may be able to spread throughout the organization in a relatively short time.
結果，在一個相當短的時間內，病毒就能在該機構之內到處肆虐。
Each of the infected programs in each of the infected machines can execute whatever other instructions the virus author intended.
在每臺受到感染計算機內的每個受到感染的程序，就可能執行病毒作者原想要執行的任何指令。
If these instructions are harmful or disruptive ,the pervasivences of the virus may cause widespread harm
如果這些指令是有害的，有破壞性的，那么病毒的蔓延就可能引起廣泛的破壞。
Traditional security measures have attempted to limit the number of security incidents to an acceptable level.
傳統的安全措施，曾試圖限制安全性事件發生的數目到一個可接受的水平。
A single incident of lost files in a year may be acceptable loss, for instance.
例如，在一年中只發生一次文件丟失，這樣的損失可能是可接受的。
While this is important it only addresses partial,because single virus is able to spread throughout an organization.
雖然這是個重要問題，這只是表明了病毒的部分問題，因為單個病毒可能傳遍整個機構。
the damage that it could cause may be much greater than what could be caused by any individual computer user.
所以它引起的破壞就會比任何單個計算機用戶引起的破壞大的多。
Limiting the number of initial vital infections of an organization is important,but it is often not feasible to prevent them entirely.
限制某機構初始嚴重感染病毒的數目，是至關重要的，但對它們的完全杜絕又常常不大可能。
As a result ,it is important to be able to deal with them when they occur ,and to take actions to erase them.
因此，重要的是，當它們一旦發生時，有能力對付它們并能采取措施消除它們。
