The importance of computer security is an issue that many people tend to ignore. But this should not be so. If you neglect maintaining your computer's protection, the very least thing that can happen to you is having your computer rendered useless because of the spyware and malware bogging your system. At the very worst, you may see your finances and your life ruined by identity theft.
We all know the old adage: "An ounce of prevention is worth more than a pound of cure." If you want to save money on possible computer repairs for data loss because of malicious code, or if you want to save yourself from the tragedy of identity theft, you will take the matter of computer security very seriously. It is not that difficult to keep your machine protected. All you need to do is to install the three pieces of software listed below.
1. Anti-virus software. As its name suggests, anti-virus software will keep viruses, computer worms and Trojans away from your computer. It is supposed to scan your files or anything being downloaded into your computer for any malicious code in real time. You can also use it to deep-scan your computer for any virus hidden in your computer system.
It is always suggested that you use professional-grade anti-virus software. Norton AntiVirus, McAfee VirusScan and Trend Micro are just some of the professional-grade anti-virus software that you can buy. However, if you cannot afford to buy software, you can always download reputable freeware like Avast or AVG.
2. Firewall. Another piece of protective software that you should have to ensure your computer security is a firewall. A firewall is supposed to limit access to your computer using a network or through the Internet. Ideally, outgoing information from your computer will be encrypted for your safety. In the same light, only safe data or data that you permit will be allowed into your system.
Windows users will have Windows Defender as their built-in firewall. It needs to be updated regularly using the Windows Update service. But you can buy a third-party firewall if you want more protection. If you are the administrator of a network, you can also install hardware to augment your firewall.
3. Spyware scanner. The last piece of essential software that you should have is a spyware scanner. When we surf the Internet, we sometimes visit websites that are not as straightforward and trustworthy as we want them to be. A spyware scanner will block any malware or spyware that will try to wriggle its way into your computer through the Internet.
The Internet can be a scary place. If you do not exercise caution in implementing your computer security, you run the risk of destroying your computer with malware eroding your system. Data loss can be undone by a successful attempt at data retrieval, but it can be very costly. Nonetheless, this cost is nothing if you become a victim of identity theft and you lose all your money.
