Hygiene 101: A Small Prescription For Newbies
To Keep Windows
by William Porquet, 2009
Windows 7 Users:
I don't have sufficient information or research yet to attempt to help you with
this version of Windows. Stay tuned!
If your computer is on the Internet, you can safely assume that there
are entities out there trying to access your computer's resources
whether you like it or not. Humans, and self-replicating programs
grab anything that isn't nailed down. Not just your private files can fall into the clutches of the bad guys, they can also use your computer's processing power and Internet access for nefarious purposes too! Furthermore, in this game, anything that can
be pried loose is not nailed down, so you have to do more than just
install Windows on your computer and expect a stress-free online
experience. It might seen like a lot of steps to secure your home PC
running Windows, but I assure you it's worth it.
I have personnally witnessed this
scenario: A new installation of Windows 2000 is connected to the Internet
for the first time (via a dialup connection no less). Before an
antivirus program could be downloaded and installed, an Internet worm
(a type of network virus) had already installed itself from some other
infected host across the Internet!
Protecting your computer from viruses, spyware, malware, and hacking
attempts will make your life a lot easier. If you don't think you have
anything on your hard drive worth worrying about, ask yourself how many
things you purchase online with a credit card. This credit card
information could be stored on your hard drive, and if accessed by a
hacker could render you the victim of identity fraud. It's no fun
having to fax all the credit bureaus to report that someone is
currently having a shopping spree at your expense (I write from personal experience here, though I doubt the sensitive information came from my own computer). Or you could have
your private emails copied to a hacker's hard drive. Follow this
prescription for a clean bill of Windows health, and your online
experience will be less stressful. And because this formula relies on
freeware and Open Source programs, the only cost to you is your time
There are 4 main steps to this process. They merely involve getting on
the Internet, downloading a few programs, and installing them.
Hopefully you'll have a faster broadband connection, but you could do
over with a dialup connection with enough time and patience. You may be
surprised to find out that your computer has already been compromised
in one or more ways!
1. Protect yourself against existing or incoming computer viruses,
email worms, malware, and spyware:
* A free antivirus program
with regular virus definition updates (I use this on my home Windows workstation),
* Use AntiVir's "Internet Update" feature frequently, sometimes viruses can spread very quickly
before anyone (including antivirus companies)
know anything about it.
* An online free antivirus
scanner (may be useful for an initial scan or if you want a second
opinion, but only runs manually):
* One more link, for when you're not sure if the "virus
warnings" your friends email you is legitimate or bunk:
* Microsoft makes patches
available for known "holes" in the operating system which can be exploited
by hackers or viruses. You can download
and install them automatically with the Internet Explorer browser:
* While this is not technically a hack attack nor a virus, the Windows messenger service
represents an example of how some random amateur hacker can rattle your
chain across the Internet from his parents' basement. By taking advantage of an obscure Windows
service designed to send public announcement
messages across an office network, spammers can remotely create a pop-up window
on your computer containing any text
they like (usually spam, and often not for polite company).
The real annoyance of this is that you don't even need to be running a browser to get it! I
recommend disabling Windows Messenger
pop-ups (not to be confused with online chatting programs like Windows/MSN
Messenger). If you're running Windows XP or Vista, you're probably fine, as this service
is disabled by default. If you're curious, though, feel free to read
along anyway to see how some of the infernal workings of Windows works:
* Spyware is a sneaky piece of software that can piggyback on another program, keeping track
of your online behaviours, collecting
data and demographic information, and even redirecting your Web page requests (like
Google searches) to someone else's page! Get one or both of the
following spyware killing programs and make the spammers mind their own
business! I bet you think you don't have any spyware on your computer already. If
you haven't heard of spyware before (but you have heard of BonziBuddy or
FREE SCREENSAVERS!), there's a good chance your computer already has some.
* Free Spybot Search & Destroy:
* Free Lavasoft Adaware:
* You can use either or both of Spybot or Adaware. Adaware is probably preferable for
beginners, just because it's harder to mess up your system
accidentally. Spybot Search & Destroy is powerful, but it won't stop you
from doing stupid things, because that
would also stop you from doing clever things. Keep in mind, some programs (particularly
popular file-sharing programs like Kazaa)
may stop working after you remove/disable spyware. Them's the breaks.
* Remember that installing antivirus software will not protect your computer in all circumstances.
Don't open unknown email attachments.
* Don't open unknown email attachments.
* Don't open unknown email attachments, no matter how appealing the message may be! If you're
certain you want to open an email attachment,
save the file to your hard drive (don't run it!) and scan the file *manually* with
your (recently updated) antivirus software
*before* you open it. With many antivirus programs (including AntiVir) you can
scan a file quickly by right-clicking
on it and choosing something like "scan for viruses" from the
2. Consider installing a software firewall to help prevent new viruses,
spyware, trojans, and hacking attacks:
* Windows XP and Vista come with
a built-in firewall. It's not bad, use it. Keep in mind it's not a
bullet-proof vest, but it can definately help protect your computer. If
you're running a version of Windows older than XP like Windows 2000,
consider installing a third-party firewall such as ZoneAlarm:
Windows 95/98/98SE/Me take
note: you are using an older version of Windows. Microsoft and
third-party software vendors have all but abandoned support
for these operating systems versions. I have found a free firewall that
still supports your version of Windows, for now, but you might want to
move up to Windows 2000/XP soon if your computer can handle it!
* The Windows firewall is
"trainable" so you can specify which of your programs is allowed to use your
Internet connection. You'd be surprised
how many programs "ping the mothership" by sending information packets from your
computer without your consent or knowledge!
3. Not all programs that access your email and browse the Web are
* I highly recommend
avoiding Internet Explorer and Microsoft Outlook for Web browsing and
email. They are both veritable flypaper
for viruses, spyware and malware. At the risk of ranting, I'll try to
explain simply why I don't like or recommend using Internet Explorer.
When you double-click on your "My Computer" desktop icon, you're
opening "Windows Explorer" (the file manager that lets you explore your
hard drive). But in a sense, you're also opening Internet Explorer too!
Surprised? Confused? I was too. If you type in "C:" in the address bar
of Windows Explorer and hit the return key, you'll see the contents of
your hard drive. And if you type "google.com" into that same address
bar and hit return you get to Google via Internet Explorer! In other
words, Internet Explorer is intimately connected with your entire
operating system. Some viruses, spyware, and malware are spread through
the World Wide Web and can take advantage of weaknesses of this
intimate integration to install themselves silently on your computer.
Mozilla Firefox, on the other hand, is just a program that has no
special privileges with the operating system.
Imagine if cars were built like Internet Explorer and Windows. If some
vandal ripped off your radio antenna, your transmission could fall out!
* I recommend and use
Mozilla Firefox and Thunderbird, respectively, as a browser and email client.
It lets you browse the Web without annoying popups, the email client has
sophisticated spam filtering built-in, it's less suceptible to viruses while
browsing or reading email. What's more, it's free:
* There will probably be
sites that refuse to work properly unless you use Internet Explorer. Use
it if you must, but the less the better,
and make sure it's the newest version you can install for your version
of Windows. I still suggest avoiding Outlook.
4. Don't forget that Windows needs some attention now and again for
system housekeeping. Running a disk check and a defragmentation
("defrag") on your hard drive(s) now and again (at least once a month)
is a good idea. And ask yourself - if you woke up one morning and your
computer didn't boot, do you have a backup of your important files
anywhere? We can easily take for granted that our files are where we
left them, but all magnetic media (like your computer's hard drives)
are quite delicate and highly susceptible to physical shock.
Most of the computer failures I've seen in my years of experience doing
systems administration and support were due to hard drive failure!
To put it bluntly, saving to magnetic media like hard drives and floppy
disks is like writing in the sand. Even backing up to CD-ROMs or DVDs
can be dicey, they can be rendered useless by leaving them label-down
by a sunny window for a day. Remember that simple fact before you leave
your family genealogy on only one hard drive without a backup copy.
* Disk Check (Windows XP): Click on
Windows Start, then move your mouse cursor to "My Computer", when
selections appear for your drives right-click (I'm assuming a right-hand mouse here)
on Local Disk (C:), then left-click on Properties, then click on Tools. Click on the Tools
tab. Under Error-checking, click on
the Check Now Button. A new box will appear called "Check disk options". Put a check mark in both
of the options. After you click
OK, a box will pop up saying you cannot run disk check at this time, and do you want to
start it the next time your computer
restarts. Click on OK then restart your computer.
You computer will boot into a special screen and inform you that it's
doing a disk check. Don't panic, it's not the "bad" blue screen. ;-) Be
patient, get yourself a coffee and a sandwich. It might take a while.
* Defrag (Windows XP): Click on Windows Start, then move your mouse cursor to "My Computer", when selections
appear for your drives, right-click
on Local Disk (c:) then left-click on properties then click on tools. Under Defragmentation,
click on the Defragment Now button.
After you click on OK, the previous display will be shown again - just click on OK again to start
the Defrag for your Drive C. This can take a while too, patience is a
* Backup: Your needs may vary, but consider at least backing up important files on some form of
removable storage like a diskette, an
external USB hard drive, a USB "pen drive", an iPod, an Iomega ZIP
Disk, or recordable CD-ROM/DVD-ROM.
Ask yourself, if you had to reinstall
Windows from scratch today, and erase everything
saved to your hard drive,
what would you have lost?
Personally, I use an external USB hard drive to make a full regular
backup of all my files. I also burn important documents and projects to
CD-ROMs. I even keep a backup of my backup on my iPod! If your data is
really important to you, you can't have too many backup copies! Backup
soon and often!

A special note for Windows Vista users:
My biggest pet peeve with Vista is performance. Vista requires a lot of physical memory and a powerful graphics card to work well with all the "Window dressing" turned on.
I've encountered a few underpowered computers that nonetheless were "Vista certified" and shipped with Vista pre-installed.
If you have an old SD card from a digital camera handy that you're not using anymore, you can turn it into a memory boost for Vista. This works best on laptops with an SD card slot.
Good luck running Windows, goodness knows you'll need it!
