Computer Security

Nowadays as users are using their computer on daily basis in a wide range, in the same way they are becoming more vulnerable to hackers and cyber criminals. This situation can really affect the entire computer system and it does not matter whether you are using Windows, Mac OS or Linux and is similar to smartphone as well. Generally computer security is one of the important issue for those who surf internet. The computer which is connected to internet has a wide chance of infection by viruses, malware, spyware, nasty malware and hackers which can completely make the system vulnerable, hence important data and files are lost.

One problem is common with many of them is that they don’t know how to secure their system and if some of them know, they don’t take interest in securing their computer system. One should know about computer security and should apply it so that no infection can enter the system. Well some of the steps are mentioned in this article which can clearly help you to avoid any type of infection and protect your system, stored data in it along with private information. Following the steps will help your system from any malware, virus, and thieves or from hackers and your system will be secure.

From the moment you boot up, your computer leaves footprints.
Websites leave tracking cookies, following you from page to page and
session to session, alongside the usual traces left by your IP address.
Persistent logins from Google and Facebook tie each site visit to your
offline identity. If anyone really wants to go after you, they can also
make a direct attack, targeting malware to track your movements in the
background. With the right tools, a computer is an open book.

Install anti-virus software

Always try to install an anti-virus software which is good for system and run it on your computer. Installing antivirus software is not enough but actually required is good software that can protect your system from any type of threats.

Best security via web browser

If you are using web browsers like Internet Explorer then you should know that it is full of security risks and in that case, Firefox will be better choice for you. Well for Firefox, there are few security options which you should know.

Computer administration protection

You may know that windows operating system let you to create different users like guests using the system in administrator mode. Using this process will help you to avoid from logging in as administrator and this makes your system more secure in all the crucial areas. Therefore you can create one guest user and browse easily with that user and this will make your entire system completely secure.


Always keep your password safe and difficult to guess

You should always create a password which is difficult to guess and at the same time it should be safe. This is because you don’t know while visiting the site which is safe and how they store your password. So it will be better that you use different types of password for each sites and this will make you secure. Even never share your password to any person neither to any other via any means.

Firewall protection

Firewall is one of the helpful software which completely keeps the good stuff in and the bad stuff out. It helps to block any type of threats and hackers from accessing the system. Windows have a default firewall which you can enable otherwise there are several free one for extra protection which can also be used.

Always be careful of shareware

Shareware can be harmful as it refers to free programs or software that is downloaded from several websites. This can be harmful because lots of malicious programs are bundled with these free software which is not seen and gets installed into the system. So always be attentive when you download anything especially when you get offers.

Unknown email attachments

There are several ways by which your system gets infected and email is one of them. You may have read about 5 ways to secure Gmail account previously. Several virus enters through email when attachments are opened. So it’s better that you don’t open any email that is sent to you by unknown sender. Though you have security but still no need to take risk as virus can mess with your system very easily without your knowledge.
With everyone using computers on a daily basis they are becoming more
and more vulnerable to cyber criminals and hackers. It can potentially
affect all types of computers whether your running Windows, Mac OS,
Linux or a smartphone equivalent.
The problem is that most people either don’t have the time or are
just not interested in making their computers secure. It doesn’t have to
be this way, it’s just that the information out there about computer
security is just too complicated or confusing to understand.

We hope to make a start at simplifying things. I say “make a start”
because, computer security is a huge topic, and one that many large
companies spend millions of pounds or dollars on each year.

Do you need to be connected to the internet all the time?

The answer to this for me (and we suspect more and more people) is a
resounding “yes!”, but if you have a computer running for long periods
of time and you don’t need to be connected to the internet, then it’s
probably quite prudent to switch your internet router off. Hackers tend
to prefer to exploit “always on” connections, and if your internet
connection is more sporadic, you’ll be less attractive to them.However, for most people this just isn’t going to be practical.

More and more of the stuff we do these days requires an internet connection.
With Windows 8 coming later this year and new versions of the Mac
operating system, our computers will be demanding “always on”
connections. It’s not just computers either- it’s our digital TV boxes
and even our fridges and dishwashers (assuming you have an internet ready one!). If this is
the case, you’ll need to ensure that you protect your connection to the
internet at it’s entry point- usually your router.

Make sure your router has a decent firewall

A firewall is a piece of software or hardware that (simply speaking)
lets the good stuff in and the bad stuff out. Most internet service
providers offer a free router and modem when you sign up with them. Make
sure that it has a decent firewall. If you are a tech-savvy person then
you can even upgrade the firmware (using the likes of Tomato or DD-WRT) on many routers to improve the security amongst other things.

Make sure your Computer or Device has a decent firewall

Most computers these days have an intergrated firewall built in to the operating system. Windows has the imaginatively titled “Windows Firewall” and Mac OS X has an intergrated one too (see here for more information on how to enable the Mac OS X firewall in Snow Leopard). For Linux, it depends on your flavour, but this article from Tech Radar gives a list of decent firewalls you could consider.

Install Decent Anti-virus Software

We know some people believe the conspiracy theory that some of the
software houses that produce anti-virus applications actually generate
the viruses in the first place. The thought is that they do this in
order to whip up some hysteria so that more people will buy their
product. Although it’s tempting to believe this, I don’t think there is
much truth in it. This article from Computer Hope gives some excellent points against the view. There are
some people that say having anti-virus software is a waste of time as
long as your careful and that all they do is slow down your computer.The truth is, anti-virus software is a must for almost everyone.

Yes, they will slow down your computer a little, but I think that is a pill
worth swallowing as opposed to being infected by a virus. You don’t need
to spend any money on it either. One of the best anti-virus
applications for PCs is Microsoft’s own Security Essentials which will be built in for the first time to the forthcoming Windows 8.It’s a complete myth that Mac users are exempt from viruses as the recent Mac Flashback virus outbreak shows. There aren’t many free anti-virus applications for the Mac, as this article from the Guardian recommends, you could always try ClamXav. Finally, anti-virus applications have to be updated regularly- I’d
recommend at least twice a day. Make sure you check the settings. Also
if you use USB thumb drives or external hard drives, do scan them for
viruses- particularly if the drive belongs to someone else. I know of
many friends whose computers have been infected by using an infected
drive belonging to a friend.

Keep Your Computer Up to Date

We know it’s annoying, but make sure you check your computer for
updates! I’ve seen so many cases of computers that have never had any
updates done to the operating system. Both Microsoft and Apple roll out
updates regularly to their operating systems. These can be important
security patches and you may be compromised if you don’t install them.

Don’t Visit Porn Sites (or any other dodgy or affected site)!

The problem is, that there are sites out there that are out to get you. They may have been effected
by a worm that modifies the website with the intention to infect your
computer with a virus. Some sites are there to deliberately get you.
Things are a little better these days, but there are still plenty of
cases of infected sites.  Be careful where you’re browsing- and again
make sure you’re anti-virus software is up to date.

Keep Your Password Safe and Hard to Guess.

The truth is you can’t trust any site that you give your password to
because you don’t know how they store it. It’s best to use a different
password for each website your sign up to.also highly recommend the password manager- Last Pass.
This manages all your passwords securely so that you never have to type
it on your computer (in case you are infected by a keyboard sniffer) or
store them anywhere insecurely. It also has a password generator, so
you can effectively have a different strong complicated password for
each site you visit. It is highly recommended!Finally, be careful about saving passwords on applications on your computer. Famously, the FTP client Filezilla stores your passwords in plain text. Not great for security.

Use a Decent Web Browser

Most people still use Internet Explorer or Safari for browsing. They’ve come
on in recent years- especially Internet Explorer. Still, my personal
recommendation is to use Google Chrome as your browser as it’s been
hailed as the most secure of browsers again and again.

Don’t Trust Public Wifi

If you surf the web whilst sipping your latte in your local coffee shop
beware! Did you know that much of your internet connection (web browsing
and email) is being sent over the connection unencrypted? Anyone
malicious in the coffee shop could be listening in and stealing your
passwords. If you have a 3G connection then use that, but if not, you’ll
need to secure your connection. Websites that use https (Facebook and Twitter for example) encrypt your data, but most websites won’t.

For this, you’ll need to use a VPN or virtual private network. This encrypts
your connection by connecting to a secure server in the middle. You can
build your own (as this Lifehacker article tells you), but it’s probably easier to use a VPN service. Again, Lifehacker comes to the rescue with a list of the best VPNs.

Never Leave Your Computer Unattended

We know this is obvious, but don’t leave your computer on if you’re
not around. suppose it depends where the computer is. we have a server
at home that is on all the time, but we do trust my wife not to hack in
to the computer and install a virus! It’s not enough to go to the lock
screen either, as someone could just connect a device to your computer
and steal your data or even your whole computer. It’s probably a good
idea to look at encrypting your hard drive, but that’s for another


These tips are only the tip of the iceberg. There are many other
things you can do to protect yourself. haven’t mentioned anti-spyware
scanners, computer cleaners (such as CCleaner)
and of course there is the whole chestnut of encrypting the data on
your computer and whether you can trust cloud providers like Dropbox
with your data. That’s for another post. David Haslam makes some great
posts below about making secure you use decent security settings on your
wifi connection, and in particular to use WPA or WPA2.
