"Simple rules which would help you
ensure the security of your PC"
Computers are vulnerable to plagues
of biblical proportions: viruses
that bring down entire networks,
e-mail worms that replicate at
lightning speed, Trojan horses that
hide inside otherwise innocent
programs, hackers that take over
computers, and more. With this
amount of risk that every computer
as well as its user faces, data and
hardware integrity is in serious
jeopardy. The following simple
methods are the easiest cure to this
wide spreading plague that endangers
our data.
I. First Antivirus then a Computer:
Without an anti-virus a computer is
like a safe containing gold bars
without a door, to say the least.
It’s not enough to have the
anti-virus software installed (if
you don’t have an anti-virus
package, stop reading right now and
get one); you also need to keep it
up with new viruses as they emerge.
II. Ahhh….Nice Attachments! You get
a message you think is from a friend
with what looks like a cool file
attached, so you click on it. Next
thing you know, your computer gets
Typhoid and starts spewing out
infected e-mails to everyone in your
address book. Never! I repeat, never
trust an e-mail from an address that
you don’t recognize.
III. Don’t tell me….file downloads
too! BEWARE of any Web site that
requires you to download software to
view a page, unless it’s something
familiar like a Flash plug-in or
Acrobat Reader.
IV. I knew it!…Spy ware and Pop ups.
Like Trojan horse programs, spy ware
secretly installs itself when you
download software applications,
which are normally associated with
file-swapping; it tracks your
movements online and delivers ads
based on where you surf. Pop-up ads
can also exploit security flaws in
Internet Explorer. Fortunately,
there are tools that can protect
you: For example, Ad-aware blocks
spy ware and Stop Zilla takes care
of pop-up ads.
V. Aahmmm…Spammers. Unsolicited
commercial e-mail is more than just
a nuisance; it’s also a major source
of virus infections. Filters like
Symantec’s Norton Anti-Spam 2004 and
Network Associates’ McAfee Spam
Killer 5 help trap the nastiest Spam
e-mail that even your anti-virus
software might miss.
VI. Patches for my OS?? E-mail-borne
worms and other Trojan viruses like
to exploit security holes in
Microsoft Windows and other
Microsoft programs. To prevent this
Microsoft issues many critical
updates on weekly and monthly basis
to fix these flaws that many users
ignore. DO NOT IGNORE these updates.
Also DO NOT disable the automatic
windows update option. Last January,
the ”Slammer worm” exploited a
vulnerability that Microsoft had
fixed at least six months earlier.
But thousands of infected
computers--including some at
Microsoft--didn’t have the patch
installed. Run the Windows Update
program once a week and whenever
Microsoft issues a warning and it is
recommended that you enable the
Automatic Windows Update option.
VII. Rescue Disk…The only cure for
Dying patients. When things go
really bad, a boot or rescue disk is
your first step to recovery. At
minimum, you’ll want to put the
basic elements of your operating
system on a floppy disk or Zip
media, so you can bypass the hard
disk at start-up. THE BEST OPTION IS
to Use your anti-virus program to
create a rescue disk you can use
when your system gets infected.
Label it with a date and store it
near your system where you won’t
lose it or else…..
VIII. Hoaxers > Hackers. There are
more hoaxers than hackers on the
Internet, and more bogus ”e-mail
virus alerts” than actual viruses.
Even real virus threats are
typically blown out of proportion by
the media. Type the name of the
alleged virus into a search engine
to see if any of the major security
vendors have issued an alert, and
visit the virus hoax pages at
http://F-Secure.com and http://hoaxbusters.ciac.org.
IX. Ladies & Gentlemen….The
Honorable Firewall. A firewall is
like a Security Officer for your
computer--it checks every ID at the
door and won’t let anything in or
out until you give the thumbs up.
Symantec and Network Associates both
offer personal firewall packages.
But a better deal is an Internet
security suite that combines
anti-virus, firewall, ad blockers,
Spam fighting, and other useful
applications.
X. Your SWAT Unit. Every one should
have an extra hard disk drive or a
set of Rewritable CDRs for a copy of
your data. Back up your data files
at least weekly (daily if you’re
running a business). This way even
if your luck goes for a vacation or
you fall victim to a virus or hacker
attack, you’ll escape with only
minimum damage. But if you fail in
doing so then I assure you that you
will pay heavily!
