Virus epidemic damage control system and method for network environment

A computer virus damage control method in a network system having a plurality of device nodes, the method comprising the steps of:

• (b1) finding a file having been modified in a predetermined time interval;
• (b2) determining first modified sections of said modified file,
• (b3) finding a second file having been modified in said predetermined time interval;
• (b4) determining second modified sections in said second file;
• (b5) comparing said first modified file and said second modified file;
• (b6) repeating steps (b3), (b4) and (b5) for other files being modified in said predetermined time period;
• (b7) reporting to a management server in said network system that no virus is found when all said modified sections from said modified files are not identical nor similar;
• (b8) reporting to a management server that a computer virus attack is possibly initiated when a specific number of said modified sections from said modified files are generally identical or similar;
• (b9) quarantining an area containing those of said device nodes having files with said modified sections;
• and
• (b10) transferring an antivirus task into said quarantined area for finding a computer virus and eradicating said virus.

A network system comprising:

• a management server connected to a plurality of device nodes;
• a management information database (MIB) connected to said management server;
• a task database in said MIB recording a plurality of tasks capable of being performed in said network system;
• a cure database stored in said MIB recording a plurality of cures for forming said tasks,
• an area of said device nodes isolated for having unpredicted traffic flow;
• and
• an antivirus task transformed into said isolated area for pinpointing a computer virus and eradicating said virus.
