Protecting
your computer from the "nasties" that come
from e-mail, internet browsing, and file downloading
is essential to the health of your computer (and network).
Spyware, software that downloads and installs on your
computer without the user's knowledge, and viruses have
become an epidemic. Left unchecked, spyware and viruses
can multiple on your computer until it no longer operates.
We can no longer browse the internet without protection
from these two epidemics. Fortunately, you can protect
your computer from Spyware, Viruses, and unauthorized
intrusion by implementing a 4-step process which will
protect your computer and ensure safe and efficient
operation.
1.
Install a Firewall.
A
Firewall
protects computers and computer networks from unauthorized
and/or malicious access from the internet. A Firewall
may be a hardware device, software, or a combination
of the two. Data coming into the computer from the internet
must first pass through the Firewall which examines
each message and blocks those that do not meet specified
security criteria. A Firewall is considered the first
line of defense in protecting private information stored
on a computer.
2.
Install an Anti-Spyware Program.
"Spyware"
is
a term used for software that covertly gathers user
information through the users's Internet connection
without his or her knowledge, usually for advertising
purposes. Spyware applications are typically bundled
as a hidden component in free programs (called "Freeware")
and shareware programs downloaded from the Internet.
Once
installed, the Spyware monitors user activity on the
Internet and transmits that information in the background
to someone else. Spyware can also gather information
about e-mail addresses and even passwords and credit
card numbers. Spyware's recent spread has been breathtaking.
Network monitoring firm Websense found Spyware
on 92 percent of PCs in an April study, and an average
of 28 Spyware programs running on each of the PCs found
with Spyware!
Along with the actual gathering of unauthorized information,
Spyware programs "sap" the computer's processing
power and if left unchecked, multiple and ultimately
cause the computer to crash. According to Microsoft,
Spyware is to blame in over half the system crashes!
There are several very good Anti-Spyware programs on
the market today. We recommend Adaware Plus or Spybot.
Like Anti-Virus programs, Anti-Spyware programs MUST
be constantly updated to remain effective. Installing
an Anti-Spyware program is essential to protecting your
computer.
3.
Install an Anti-Virus Program.
A
computer virus is a parasitic program
written intentionally to enter a computer without the
users permission or knowledge. The word parasite is
used because a virus attaches to files or boot sectors
and replicates itself, thus continuing to spread. Though
some virus's do little but replicate others can cause
serious damage or effect program and system performance.
A virus should never be assumed harmless and left on
a system. Anti-Virus programs monitor
and detect viruses entering a computer via e-mail messages,
instant messaging, and file downloads. Once a virus
is detected, the anti-virus program will remove the
virus by either placing the infected file in quarantine
or deleting the file from the computer. There are several
excellent Anti-Virus programs available from Symantec,
McAfee, and Trend Micro, to name a few. We recommend
installing Symantec (Norton) Anti-Virus 2006 as step
number three to protecting your computer.
4.
Regularly Update Microsoft Windows.
The fourth step to protecting your
computer is to regularly update your version of Microsoft
Windows.
Microsoft constantly releases security and performance
updates for Windows.
