excel software to work incorrectly.

software, the name therefore taken from the
Trojan Horse in Greek mythology. Trojan viruses

in reality can attack your hard drives, deleting
files and re- writing system files. They cause
your computer to become unstable, particularly
when operating system files are deleted.

Boot viruses Boot viruses attack the boot sectors
on your hard drive and interfere with your
computer's basic operation, making your
operating system run strangely or even corrupt it
all together.

. E-mail Viruses Email is probably the most
common method for spreading viruses. Plain text
email messages don't normally spread viruses.
Most email viruses are spread via attachments
to email messages, or in email messages
containing embedded executable code.

For example, your computer would need to open
an attachment or open an html link embedded in
the message. To protect yourself against email
viruses it is important that you do not open
attachments from senders whom you don't know,
or which come from a free email source such as
hotmail or yahoo. If you use an email client to
check your email, avoid clients that automatically
open attachments (like Outlook Express).
