How Do Viruses Spread?
Viruses can be spread via Internet downloads, email, and removable media such as CDs, DVDs, discs, memory sticks etc. Viruses cannot be spread on their own and must be executed by someone to cause damage.
Boot sector viruses spread when a user inadvertently boots his or her workstation from an infected floppy disk. Macro viruses spread by the simple opening of an infected document. Mass mailing viruses use email to rapidly spread, usually employing deceptive tactics to persuade the recipient to open the infected message.
Be careful not to open attachments sent to you by email from people you do not know.
