Secure Your Computer

By Dean Quek

With advancement in technology, your computer is an important tool, not to mention investment, to you; especially with everything from purchasing furniture to paying bills online, the need for your computer to be secure is increased.

Here are a few tips to protect your computer from both physical and non-physical damage.

Protection from loss of data

A hard disk will "crash" when it undergoes violent movement while in use. For example, you are on your computer, and you decide to turn and stretch yourself. In doing so, you knock into your computer, and the hard disk crashes. You have lost all your data! To prevent this, ensure that you back up your hard disk data periodically. You can back up information using portable hard disks, CDs or DVDs.

Protection from power surges

A surge protector will blow the fuse or trip the breaker when a sudden surge of electricity hits. This action will save your computer from severe damage. In addition, ensure that a surge protector is used in conjunction with your phone line. This will prevent the phone line from being a way for the electricity to travel and damage your computer.


A firewall is a software program that ensures Internet security. A firewall filters and blocks unauthorized access to ports on your computer. This will serve to restrict malicious webpages, emails or programs that may damage your computer. There are a few types of firewalls, namely stateful firewall, software firewall and proxy firewall.

Safe sites

Surf only safe sites. There are numerous sites out there that carry malicious virus, adware or spyware that will infect your computer. Make sure you have your firewall functional before surfing unknown sites. Only make transactions on sites that employ safe payment methods, like Paypal. A site that comes to mind is target=_new [http://www.ablewise.com]Ablewise.com, a popular classifieds site, which utilizes safe credit card payment clients as well as Paypal.
