How do computer viruses spread?
A computer virus is a type of malware that propagates by inserting a copy of itself into files or the boot sector of a hard drive. A virus cannot execute without a host program and often goes unnoticed by a user until it has caused severe damage. When first created, viruses were spread by people exchanging infected floppy disks. Now, computer viruses spread via the Internet, email attachments, and infected files downloaded from the Web.
One of the most common ways viruses spread is through email attachments. The virus attaches itself to an email and is sent to the recipient. When the email is opened, the virus launches and infects the computer. Another way computer viruses spread is by downloading infected files from the Internet. Once again, when the file is opened, the virus launches and infects the computer.
Computer viruses can also spread through removable media such as USB drives and external hard drives. When the removable media is plugged into a computer, the virus launches and infects the computer.
As you can see, there are many ways computer viruses can spread. The best way to prevent a virus from infecting your computer is to install an antivirus program and keep it up-to-date.
