•ScanDisk for Windows is a disk-checking and repair

includes hard disks and floppy disks), and repair most
problems that may occur.
•ScanDisk for MS-DOS (Scandisk.exe) starts

What is a virus?
• A computer virus is a program or piece of code that
is designed to copy itself into other programs stored
in your computer, and then spread itself from one
computer to another.
• Virus programs are written by computer
programmers or hackers--usually with malicious
intent--and are typically spread through shared
documents, spreadsheets, executable files, software
programs, or floppy disks.
• Viruses can do anything from displaying random
messages or sounds, to damaging data, to wiping
out the contents of your hard disk.
Virus Scan
•Anti-virus programs scan your computer storage
disks to detect viruses on your system
•It is important to scan for viruses frequently,
because you can become infected at any time.
•Virus scanning software is not a guarantee that you
will not get a virus. Each week there are more
than 250 new viruses. Virus scanning software
cannot detect a virus it doesn’t know about
•It is important if you have a computer at home to
purchase virus scanning software, and regularly
update it to detect new viruses.
