What is a Computer Virus – Keep safe with Central IT Systems
Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation.
A virus might corrupt or delete data on your computer, use your email program to spread itself to other computers, or even erase everything on your hard disk.
Computer viruses are often spread by attachments in email messages or instant messaging messages. That is why it is essential that you never open email attachments unless you know who it’s from and you are expecting it.
Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.
