How to Enjoy Safer Computing

Tuesday, June 28th, 2011

Computer security plays a very crucial role to enjoy safer computing. There are hackers who break into your computer through the Internet and steal your important information. There are also online criminals who create malicious software to harm your computer. By any means you need to protect your computer and important personal information. And this could be possible only with a strong computer security.

To protect your computer against potential security threats, you need to take several measures. For better PC security firewall, virus, spyware and other malware protection are highly important. In addition, you should also update your Windows operating system as well. In this article you will find detailed information about all of them. To enjoy secure computing you can talk to a computer tech support service provider for virus troubleshooting.

Let’s start our discussion with firewall. This is a software or hardware which checks information that comes from the Internet or a network. It is the firewall which decides whether to turns the information away or allows it to pass through to the computer and it entirely depends on the settings of the firewall. So, firewall comes to a great help to prevent hackers from gaining access to your PC. If you are using Windows operating system, there is built-in firewall and it is turned on automatically.

Hackers also use viruses, worms, and Trojan horses to infect vulnerable computers. Viruses are small programs which worms can replicate them from one computer to another and result various problems. On the other hand, Trojan horses come in the disguise of email attachment. All these malicious objects can not only erase information from your hard disk but they also have potential to completely disable your computer. To protect your computer against them you should install a powerful anti-virus program which will scan email and other files on your computer and save your PC from viruses, worms, and Trojan horses.

Another malicious object is spyware. This small software can display advertisements and collect information about you without your consent. There are many powerful spyware which can install unwanted toolbars, links in your web browser or can display pop-up ads frequently. There are also some spyware which collect information about the websites you visit or the passwords you type. An antispyware program is a must to protect your computer from spyware. There is a built-in antispyware program namely Windows Defender in Windows operating system which is turned on by default. When spyware attempts to install itself on your PC, Windows Defender gives an alert.

For safe computing, Microsoft operating system offers important updates in regular interval. This is to protect your computer against new viruses and other security threats. You should install all these updates and patches so that your computer can block all the malicious objects.

Basic Computer Security Tutorial

Recently, many anti-scam websites have been under denial-of-service (DDoS) attack by the scammers. Believe it or not, they’re using the not-so-protected computers to perform the DDoS attack. The innocent people unknowingly help this irresponsible people to perform the attack. This computer is called ‘zombies’ and the zombies computer are computers infected by virus or trojan and used by the scammers to perform the DDoS attack.

The virus or trojan will open a backdoor on target computer for the hackers so he or she will have access to the target computer. In some cases, the hackers will sell the access to another person and that person will use the access to any purpose that the he likes. If a spammer gets access to your computer, he’ll use it to send spam emails.

The DDoS attack is perform by the scammers by sending useless data to a specific web server and when the server cannot handle the data flow, it’ll crash. This is what’s happening right now to many anti-scam websites.

This is just one thing what hackers can do when our computer is not well protected. If I’m going to list what they can do to not-so-protected computers, it will be a long list. Therefore, we need to protect our computer. But, some protection come at a high price and some are free. In this article, I will tell you where you can get good optimum computer protection without paying a dime.

1. Antivirus

Your computer needs an antivirus. A good antivirus will have real-time protection, good detection rate and it’s easy to use. If you don’t have any antivirus on your PC, get one now. Antivirus can find and remove viruses and trojan from your PC. There are three antiviruses that I personally recommend. Avast! Antivirus, AVG and Avira Antivir Personal Edition.

2. Firewall

Firewall is important so you can block ingoing or outgoing traffic. If you have malicious programs on your computer, it will not be able to send out information out from your computer and firewall will be able to block it. When you’ve bought a new PC, I suggest you to activate the Windows Firewall before going online. Even though the Windows Firewall cannot protect you from some malicious threats completely, but it’s good enough to protect you before you install a new firewall. After that, you need to find a good firewall and install it in your system. I personally recommend two free firewalls. Comodo Firewall Pro and ZoneAlarm.

3. Spybot Search and Destroy

Spybot Search and Destroy is good software to find spyware, malware and adware threats inside your PC. It also has some real-time protection and best of all, it’s free. It has good detection rate and can detect keyloggers inside your computer.

4. Ad-Aware 2007

Ad-Aware 2007 Free has been used by 250 million people because it provides good protection. If you have some money to spend, consider upgrading to Ad-Aware 2007 Plus because it has real-time protection. However, the free edition is good enough if you’re tight on budget. But you need a little more work because you have to perform the scan manually and it has no real-time protection.
