Methods that guarantee a computer or network is safe from
computer viruses, worms and trojan horses simply do not exist.
Users can take several precautions, however to protect their
home and work computers from these malicious infections. The
precautionary measures are:
1. Never start a computer with a floppy disk in drive A; unless
it is an uninfected recovery disk.
2. Set the macro security in programs so you can enable
and disable macros. Only enable macros if the document is
from a trusted source and you are expecting it.
3. Install an antivirus program on all of your computers.
Obtain updates to the antivirus signature files on a regular
4. Check all downloaded programs for viruses, worms, or trojan
horses. These malicious-logic programs often are placed in
seemingly innocent programs, so they will affect a large number
5. Never open an e-mail attachment unless you are expecting
it and it is from a trusted source. Scan for viruses in all
e-mail attachments you intend to open. Turn off message preview.
6.Write-protect your recovery disk by sliding the write-protect
tab into the write-protect position.
7.If the antivirus program flags an e-mail attachment is
infected, delete the attachment immediately.
8. Before using any floppy disk or zip disk, use the antivirus
scan program to check the disk for infection. Incorporate
this procedure even for shrink-wrapped software from major
developers. Some commercial software has been infected and
distributed to unsuspecting users this way.
9. Back up your files regularly. Scan the backup program
before backing up disks and files to ensure the backup program
is virus free.
