Top ranked viruses for past five years
Virus Categories:
Viruses can be categorized in five types according to various characteristics:
- File infector viruses: Infect program files
- Boot sector viruses: Infect the system area of a disk
- Master boot record viruses: memory resident viruses that infect disks in the same manner as boot sector viruses
- Multi-partite viruses: infect both boot records and program files
- Macro viruses: infect data files, such as Microsoft Office Suite files with macro script capabilities.
The new viruses are harder to eliminate. The cost of cleaning up after a virus infection has risen. According to a latest virus prevalence survey, the average cost to companies was $81,000 with $69,000 in the last survey.
