1. How to keep your computer safe enough?
Nowadays, we use computers for everything from banking
and investing to shopping and communicating with others
through email or chat programs. Although you may not
consider your communications "top secret," you probably
do not want strangers reading your email, using your
computer to attack other systems, sending forged email
from your computer, or examining personal information
stored on your computer (such as financial statements).
However, if your computer is infected with a virus, then
what will happen? It can not only mess up your system files,
but also may enable cyber criminals to gain remote access
to the compromised PC system. Thus, if a user has limited
security precaution, it is easier for them to get infected by a
computer virus.
At the first beginning, users should know that computer
security is the process of preventing and detecting
unauthorized use of your computer. Prevention measures
help you to stop unauthorized users (also known as
"intruders") from accessing any part of your computer
system. If your computer is infected with a malware,

2. hackers can gain control of your computer so they can use
it to launch attacks on other computer systems. Having
control of your computer gives them the ability to hide their
true location as they launch attacks, often against
high-profile computer systems such as government or
financial systems. Even if you have a computer connected
to the Internet only to play the latest games or to send
email to friends and family, your computer may be a target.
Intruders may be able to watch all your actions on the
computer, or cause damage to your computer by
reformatting your hard drive or changing your data. Thus, it
is very important for you to learn how to prevent your
computer against viruses. In some cases, an improperly
secured computer can also result in the theft of personal
information, such as credit card or bank account numbers.
Having a secure computer is an important step that you
can take towards protecting your personal information.
Firstly, you should install a reliable antivirus program to
protect your computer. Having virus protection is a very
useful way to ensure that your computer is protected
against potential security issues. Many people do not have
virus protection because many programs cost from $20 to

3. $50 for basic levels of protection. However, there are also
many free antivirus programs which can help to protect
your computer such as Microsoft Security Essentials,
AVIRA AntiVir etc.
Secondly, you should take control of your email. Avoid
opening email attachment received unexpectedly unless
you can believe it is from the trusted sources. Remember
most Trojans or Worms can be spread all over the email.
You must make sure your email client isn't leaving you
open to infection. Keep an eye on your email and never
open the malicious attachment.
Thirdly, you have to keep your firewall on and make sure to
update your antivirus programs regularly. If you have
antivirus software but don’t always make sure it’s always
updated, you may as well just offer your computer’s
sensitive data up to hackers. With new strains of malware
being produced every day, security software must be
updated just as often to best protect your computer.
Fourthly, due to the large amount of information on the
internet, most computer users spend their time online.
However, there are many malicious websites that are

4. designed to scam money from users. If a user has ever
visited those sites, he or she can get viruses installed
easily. It is suggested users to make sure if a web site is
legitimate or not before you go there.
Last, user must have a good habit to back up data
regularly in case they get infected by viruses and lose
everything. Once back up, users can recover photos,
music, movies, and personal information easily.
Users should follow the tips above in order to secure your
computer and ensure computer can be running in a safe
network environment. It can help all the computer users to
prevent most of viruses and malware. However, viruses
are created by criminal everyday, few of them still have
ability to access your computer through system's
vulnerabilities and escape the detection from your antivirus
program such as the most popular and notorious
Ransomware called FBI Moneypak Greendot Virus.
Once detect, users can search for Online Tech Support for
help instead of taking the computer to the local repair shop
which may cost more money and rather time consuming.

5. Anyway, it is a must for every PC users to keep the
computer safe enough.
