No matter which type of computer operating system you own, it can be very confusing deciding what software you should purchase. Since updates continually take place, you definitely don’t want to spend money on something that is going to be changed in the near future. Software can also be quite expensive, so you want to make sure you are getting the best possible price.
At free software download websites, you can take advantage free software for your computer system. Many free software sites contain a wide variety of applications for computer system maintenance and security. For those of you who depend on your computer for more than entertainment, you know how vital that is. Other types of software available include billing, system recovery, and software to help you develop your website.
Since software is so expensive, why not check out what free software sites have to offer for free before you spend your money on it? Chances are you will find a variety of software products available that will work well for you.
One of the disadvantages of free software sites is the risk of spyware or adware. This problem is easily avoided by using sites such as CNET's download dot com, which does not allow any software with adware or spyware. Many other sites also use a scanner system to alert you if a piece of software contains any adware, spyware, viruses, or other unwanted components.
Another possible disadvantage of free software is the lack of support available. This is something you should consider – if the software you need is crucial to you and you will need good support, you may need to buy the software. If you can make do with lesser levels of support, free software may be the best way to go, though. Many free applications do offer support via user forums and online help centers.

How Computer Viruses Work and How to Protect your Computer
Many people are afraid of tinkering with their computers because of the
fear that they might inadvertently introduce a computer virus into the
computer system.
Computer viruses have become the technological bogeyman that scares
computer users all over the world. We have all heard of how dangerous
computer viruses are and how it can damage your data. Of course, aided
by the bloated images Hollywood movies paint with regards to computer
viruses, a big majority now have this insane (but mostly unfounded)
fears about it.
It is true that computer viruses are dangerous. Anyone who has lost
vital information in their computers because of a computer virus will
know how big a damage it can cause. But computer viruses are not these
insidiously little pieces of code that could wreak havoc on the world.
If you know what to do when you get a virus in your computer then you
can definitely limit, if not totally stop, the damage it can cause.
But what is a computer virus? Well, it is a software with a small
imprint that would usually attach itself on to a legitimate program or
software. Every time this program is executed the virus is also
executed and it tries to reproduce itself by attaching to other
programs or it immediately starts affecting the computer. A computer
virus and email virus basically have the same modus operandi, the
difference though is that an email virus would attach itself to an
email message or automatically send itself using the addresses in the
address book in order to infect the people who receive the email.
A computer virus is usually embedded in a larger program, often a
legitimate piece of software. The virus will be run when the legitimate
software is executed. The computer virus would load itself into the
memory of the computer and then it will seek out any programs where it
can likely attach itself. When a likely program is found then the virus
would modify the file in order to add the virus’ code to the program.
The virus would usually run before the actual legitimate program runs.
In fact, the virus would usually perform the infection first before it
commands the legitimate program to run. This process is so fast that no
one would even notice that a virus was executed. With two programs now
infected (the original program and the first infected program), the
same process would be repeated whenever either program is launched
worsening the level of infection.
After the infection phase, or even within the middle of the process
of infection, the virus would usually start its attack on the system.
The level of attack can range from silly actions like flashing messages
on the screen to actually erasing sensitive data.
Fortunately, there are steps that you can do in order to protect
your computer from viruses. Among the steps that you can take are:
* The simplest way to avoid a virus is to install a legitimate and
effective antivirus program in your computer. The antivirus program is
designed to look out for any kind of activity that could be seen as
similar to a virus attack or infestation and it automatically stops it.
* You can opt to use a more secure operating system in your
computer. For example, Unix is a secure operating system because the
security features built into it prevents a virus from actually doing
what it is programmed to do.
* Enable Macro Virus Protection in all of the Microsoft
applications resident in your computer. Additionally, you should avoid
running macros in a document unless you have a good idea of what these
macros are going to do.
* Avoid using programs that you have downloaded on the internet especially when they come from dubious sources.
* Never open an email attachment that contains an executable file – these are files with the EXE, COM and VBS extensions.

Some Tips About Software
The term software is generally used for computer software that is an essential part of the computer system. It stores and process all encoded information or computer instructions on PC. Computer software has very vast scope in computer world.
According to computer science and software engineering computer software is all information that is processed by computer systems, programs and other data. Software is completely opposite to hardware, which is used to store or execute the software. Software is loaded into random access memory and then executed in central processing unit. It belongs to machine language that is not easy to understand for the users.
Every operating system has its own software that requires an individual processor. It understands machine language that consists of several groups of binary values, which gives processor instructions and data. Software converts machine language in simple language that enables the users to understand machine language.
Software generates a connection between electronic hardware and data. The user can operate the sequence of data instructions with the help of software. Software can use any type of data such as output/input. Sometimes the output of software can be input for another software. Software provides an interface between hardware, data and other software.
Software can be divided in three classes such as system software, application software and programming software. System software enables the users to run computer hardware and computer system including operating system, device drivers, diagnostic tools, servers, windowing systems and some more.
Users can perform one or more tasks simultaneously with the help of application software. With the help of application software, they can perform all applications like office suites, business software, databases and games. Whereas the programming software offers some functional tools that enables the programmer to write difficult computer programs. Programming software provides some useful tools like text editor, compiler, interpreter, linker and debugger etc.
After installing software a computer can operate that vary software. Application software passes the instructions to system software and then computer program executes on computer.
