For everyday personal use, you don't really need to find the best antivirus firewall software that's intended for industry or business use. Often, personal home use (i.e., not used for profit or for business) necessitates only the minimum and basic features of a computer security solution.

Needless to say, personal or home versions of whatever you consider to be the best antivirus firewall software for your private use must be able to detect and remove all types of computer threats such as Trojans, worms, rootkits, and other malware types. It must also protect your computer from hackers that will try to access your personal information from your computer.

If you don't mind consuming a significant portion of your hard disk for your security programs, you can install both an antivirus application and a personal firewall separately. However, why go through all that trouble when you can easily find a security suite that functions as both a virus defense program and firewall at the same time?

A computer can be the best tools that you have that will make all of your work easier. Also, a computer can be the best entertainment center that you can use to watch a movie, listening to music or playing video games. But, you won't get all of those benefits if your computer was crash because of virus, Trojan, malware, worm and other threat that you can get from many source. It can be from the internet, removable drive and other media. Therefore, you need to have good defense against all of those attacks. And here the antivirus part takes an important role. But, to find best antivirus that can protect your computer and all of the important file that you save in it, is not only from the feature that the antivirus has or the price, but also you need to find the antivirus that match with your computer. So, if you're a Linux user, you need to use antivirus for Linux.

We all know that Linux is one of the best OS (Operating System) that has best defense against virus and other threat attacks. But, if that so, you still need antivirus for Linux. It's needed in case there's new variant virus that has stronger attack that also can penetrate your Linux defense. But, you also need to choose the antivirus that perfect for your Linux. Most of the problems that happen in installing antivirus in Linux is kernel problem.

There're many antivirus for Linux that you can find on the market, like Kaspersky, Avira and others. You can get the free version or the trial. But, if you want to get best protection, it's better if you get the full version. So, even for the freest virus attack OS like Linux, you still need to use antivirus to get the extra protection. So, you can get comfortable in using your computer and your important file will be safely protected.

The reason that viruses are constantly floating around the Internet is their ability to replicate themselves. They can make copies of themselves in various types of data files. A virus may start harming your computer the moment that the file that it has corrupted is executed. This can cause serious damage to your computer although other viruses can be just a nuisance and bug you more than anything else. There are a few different types of viruses and it's important for you to know which ones are which.

Firstly there are memory-resident viruses. This type of virus is not looking for other hosts to infect once it in executed. A memory-resident virus waits until the computer user opens files so that they can corrupt them. They can replicate themselves but do not possess the ability to find other hosts.

We've often seen it in movies and in commercials; the distressed owner of an infected PC would call for some hired help who'd work miracles and clear up whatever bugs that may have gotten to the PC, charge a bomb and then drive away. Well, instead of being that distressed person, why not learn the basics of computer security so that you can tackle problems while they're small instead of letting become big issues that will burn holes in your pocket?

First you must know what you'd be up against when something hits you. Years ago, the only thing that could hit you would be a virus, but now there are more than 140,000 malwares that can hit your computer and it will cause more harm and damage than you could ever imagine. There are viruses and worms, which will affect the codes of your system and replicates then the little replicas, would attack your files by deleting them, corrupting them, altering your computer settings, manipulating system codes or worse, leaving your computer in a state that makes it unusable. Worms are just the same, only they are self replicating and don't need to attach themselves to your system, but they too can leave your computer in ruins.

Small to mid-sized business executives and managers often worry about the security of their company's sensitive files. What is the best way to harbor a healthy flow of information while keeping your company information secure?

Most of this kind of sensitive information should not be stored on a computer's hard drive. If someone were to get a hold of client credit card information the company is subject to lawsuits. Instead, consider using a third party services that manages this for you such as PayPal, eBay or AcceptPay. These processors can facilitate transactions but more importantly keep credit card data out of employees' or hackers' reach which will limit the company's exposure and decrease the risk for fraud and identity theft.

Human resource records are an example of information that requires special attention. Be mindful of this and other sensitive company information because what is stored electronically may become a liability.
Most information should be free flowing between departments and staff members. If employees sense that you are trying to hide something there is likely a larger issue to address. Staff should have relevant and pertinent company information related to his/her job function. 

Often no thought is given to support of computer equipment in offices and business of every kind. When trouble happens maybe Jack in accounting can handle it, or Sylvia's nephew, or just anyone. Not enough planning has been given to this time and the solution may be slow in coming.

Slow PCs are another big problem. Often this means a computer virus and your PC support needs to understand this problem, know what the latest viruses are and know how to remove them. What would it mean to your business if a virus ravaged your PC network?

Computers are one thing, it takes a certain skill level to replace a hard disk or a fan on the CPU, upgrade memory, or install Microsoft Office. Beyond these things the skill and experience level needed increases and it is difficult to just invite anyone in to accomplish what is needed.
These higher level IT support skills require time to gain the experience needed to effect quick repairs. Even looking to certifications is no guarantee that sufficient real-world experience is there to get your business back up quickly.

Consider the real danger that your business may be in because of network and PC security...

Ways to Protect Your PC
Firewalls. A component of a network or computer system that is  intended to block system access that are not authorized while allowing authorized interactions and communication. Firewalls are executed in either software or hardware, or integration of both.

• For those already connected with the Internet through a router, there's no need to install 'all-in-one' security software since your router now serves as hardware-based firewall to restrain bad guys, Internet worms, trojan horses and viruses from having access to your system.
• As part of MS Windows Security Measures, as with the XP and Vista, built-in software firewalls are already integrated with the package to protect you from bad elements that causes system destruction.
• Turn on your Windows XP firewall by clicking: Start button then click Control Panel then Security Center icon then click the Windows Firewall situated at the bottom of the window.
•  Read information about Firewalls and you may download free software firewall that will accomplish tasks to keep you protected.
