Earlier when technology
was not advanced, human beings used to work in paper files and those documents used to
be kept safely in almirah and if document was of utmost important that time there
used to be a strong lock in order to have more protection and at times
protection of room was also required. Whenever some mischievous people intended
to steal the documents, they used to scan the building, room etc, purpose was to
find out weakness in the building, room and almirah. Or we can understand it
like if you do not lock your vehicle, it is insecure. Now we are living in a
era of technology so things have changed a lot. Presently we use computer to
store our documents, files and important conversation etc. So we need to
protect our computer likewise, hackers try to find out loopholes in the
computer and technology. Therefore you need to maintain your computer security
in order to block all vulnerabilities.
Here are few suggestions for best computer protection which can be implemented
to avoid intrusion into the computer:
Make sure that firewall is turned on. It is very vital tool to stop a cracker
from gaining access to your computer. If it is home computer then single
firewall is sufficient but in case of a organization's computer where data is
more crucial, some hardware tools ie router which also comes with firewalls.
Install a legal and antivirus software, avoid using pirated one. Pirated antivirus
program is not able to provide required protection. Do not forget to upgrade
anti viruse or you can configure those for auto upgrade option. New viruses
also come on daily basis, so regularly check the antivirus manufacturer's
website for updates. Most antivirus programs are sold with annual
subscriptions, which can be renewed as needed
A computer virus is the common
problem. Computer virus gets install into your computer system and as you run a
program to which virus is already attached itself. Virus reproduces multiple
copies of itself from your computer only.
One good example can be of
"Trojan horse" programs. Trojan horse programs are similar to
viruses, but these do not reproduce their multiple copies. Normally Trojan
horses tries to install a malicious program into your computer. Sometimes due
to malicious program into your computer, it may start doing some very funny
activities like auto booting itself. If it is your home computer the you
may try some freely available anti virus programs like AVG, avast etc for best

programs for best computer protection specially for home users.
Install anti spyware software, it stops a malicious user from peering into your
computer. Malicious users quietly send spyware program to your computer so that
without your consent they can theft the data or can produce advertisement popup
whenever you browse internet or access social networking websites. Nowadays
most of the operating system comes with inbuilt anti spyware programs but
should be keep on upgrading your operating system in order to upgrade anti
spyware.
Attentively download anything from internet or do not open an attachment which
comes via email as it may contain some harmful exe (executable) files. As you click on
those, they install malicious code in to your computer.
Upgrade operating system on regular basis because manufacturer periodically fix
the security holes.
For emails try to use Microsoft outlook or windows email as they are quite capable
to restrict the virus entry.
Do not forget to turn off your computer once you finish your work. Sometimes
crime could take place just because the computer, built-in camera or printer
etc was on. Sometimes crackers use your computer resources without your
knowledge and they may indulge in some illegal activity.
Take regular backup, anytime anything may happen so better to be alert than
sorry.
Nowadays almost everyone is on internet, visually roaming here and there,
downloading and uploading files, If you are not careful then crackers may crash
your computer, can send pop ups of bizarre messages.
Delete unknown emails; never click on advertisements links, or any link which
directs you to some other website.

will be hard to crack.
