Virus and Spyware

Other Virus Protection and Spyware Sources


Computers come bundled with some kind of virus and
spyware software
these days. Whether it fits your needs,
wallet or expectations is another matter. Some seem
obtrusive while you wonder if others are even working. When
was the last time it ran a system scan or updated its
definitions?

In an ever fluctuating market, different anti-virus vendors are
all jockeying for 1st place position as the top supplier of
choice. It all depends on what you are looking for and how
much you want to spend.

It's best to do some research of your own if you are not
happy with the service provided by your anti-virus supplier or
with the cost of that service. Two companies that you might
want to look into are:

McAfee

Norton
Virus and Spyware by PC Apprentice 2009
Virus and Spyware are a major concern for businesses
and the home user alike. Although there are different
types and names the concerns from the home user's
point of view are the same. "Am I protected?" and "What
can I do to make my computer safer?"

The best protection you can have for
virus and spyware
is an Anti-virus program and to make sure that the virus
definitions are up to date. Virus definitions, also known
as Virus signatures, are patterns of code that resemble a
virus string. Your
Anti-virus software uses these
definitions to recognize potentially harmful code on your
computer.
Symptoms that you have a Virus on your computer can include:

• Your system runs slow.
• The computer crashes, this might be with or without an
automatic restart.
• Error messages constantly pop up.
• Programs or files open slowly or not at all (especially security
programs).
• You no longer have access to drives or other storage media.
• Certain Web sites won't open in your browser, these include
anti
virus and spyware software
vendors.
• Your Anti-virus software has stopped updating automatically and
you cannot perform this action manually either.
• You can no longer print.
• Programs disappear from your system.
• Strange icons are added to your desktop, or programs appear
that you never installed.
• The unused space on your hard drive disappears (which could
mean a
worm is replicating itself).
• People in your contacts list receive e-mail from your account,
often with a virus attached.
• There's a big jump in the amount of traffic on your network,
especially outbound.
Changes to your computer configuration

You may find that settings on your computer have changed. This can be a different
homepage on your browser, a different default font or search option. If you change
these back to your original settings and they return when you restart your computer
you most likely are the victim of Spyware.

Web browser contains components that you didn't download

Spyware can add toolbars to your Web browser that you didn't download. If you remove these toolbars,
they might return each time you restart your computer.
Imagine that your Anti virus and spyware software is an Old West Sheriff and the virus definitions are
Wanted Posters. You want the Sheriff to recognize the bad guys and blast them as they enter town.
Making sure that your anti-virus program can run
updates is your part of making your computer more
secure.
Symptoms that you have Spyware on your computer can include:

Getting pop-up and pop-under ads at all times

These annoying ads "pop" up all the time. You have no idea why you are getting these ads and you haven't clicked on
anything to justify it. A good indicator is that you do not even have a web browser open and you are being bombarded
with pop-up screens. This is a common occurrence of virus and spyware activity.
Your computer runs slower

Spyware is not coded to be efficient. Resources these programs
use can slow down your computer and errors in the software can
make your computer crash. If your computer is slower than normal
at performing routine tasks, you may have spyware on your
computer.

Prevention Tips

Make sure that you use the Windows Firewall; this won't prevent
spyware that you download as part of a "
free" program but will
deter hackers from gaining access to your computer.

Always make sure that Windows and your other programs are kept
up to date as this will make sure that you have the latest
security
updates
and any security "holes" have been taken care of and
cannot be exploited by virus and spyware.
Be wary of free programs (many of these contain virus and spyware) and never click OK to close a window that has popped
up on your screen. NEVER trust any message on your screen that says that your computer might be infected, no matter
how legitimate it looks. Press Alt+F4 to close the window or use CTRL+ALT+DELETE to open the Task Manager and
close the Internet browser from the Applications tab. By clicking on the window itself to close, you may actually be
accepting whatever the program is. These downloads are often so quick you may not even know that you have downloaded
everything. To top this off they may try to sell you a spyware removal tool to remove the spyware they gave you in the first
place. Buyer Beware!!!!

To remove Virus and Spyware you can use Windows Defender. This comes bundled with Windows Vista and will be
included with Windows 7. If you are running
Windows XP you can download Windows Defender here:

Windows Defender Download
There are also free virus and spyware protection programs out there such as: Avast

As far as
spyware detection software goes you can find many sources, most of them offering free software. We've already
mentioned the Windows Defender program but there are also others available:

Spybot - Search and Destroy

Ad-Aware

Yahoo Anti-Spy (This one comes with a Yahoo Toolbar)


The best defense against virus and spyware is an informed user. If you know that your computer is starting to display
signs of an infection you can begin to fight back for control of your computer. Being adequately protected to stop
intrusions in the first place can save you a lot of headaches and worry. After all it's your information that is on your
computer. So be informed, up to date and aware of the dangers of virus and spyware.
