Computer Viruses and Data Security

Viruses have the potential to infect any type of executable code, not just the files that are commonly called ´program files´. For example, some viruses compromise data security and infect executable code in the boot sector of floppy disks or in system areas of hard drives. Another type of virus, known as a ´macro´ virus, can damage computer security by infecting word processing and spreadsheet documents that use macros. And it´s possible for HTML documents containing JavaScript or other types of executable code to spread viruses or other malicious code.
