[Emiliio]

Hi,
I am always confuse while downloading from internet. I am using Windows Vista. I was downloading an free audio player for Vista. It shows a Shareware license. Then I took another one and that shows a freeware license. What does it means. Both are available for free downloads then why this categories. Second thing I want to know how does a virus works. And their causes. Thanks.

Shareware software's are for free distribution, i.e that can be copied freely, to facilitate the user to test the program to see if it serves their needs. However, if you decide to use it once past the probationary period (15 or 30 days, generally) should buy it or stop using it. This is too much similar to a trail period. It basically means a temporary license for a software.

Shareware simply means a trail software. When you download a tool you get a process called registration and that includes sending data from the buyer to the seller in addition to the payment itself. The price of these programs is lower than my commercial software, because, among other reasons, the sale is made directly from manufacturer to user, eliminating the costs and trade margins from the distribution chain.

Freeware is a software that is freely distributed. In some cases, the programmer calls for donation as per the use need. The motive here is to distribute free programs without any license. You can share the same with other users also and on the internet. On the other hand shareware is used as an initiative for giving look of the software.

Virus are the most common and annoying threats on the internet. It is created by malicious writer to harm the users without his knowledge. There is also speculation that many viruses are created in secret by the same companies that sell antivirus. That is also true but there are not some sure reason for this. It is very important not to execute any file you receive by means of the preceding paragraph that we have not found by antivirus program. It is also advisable that you always have an updated antivirus program (outdated versions will not be ready for the latest viruses). In any case, just in case, should always have a copy on diskette or otherwise, of the important information we have on our computer.

The virus is activated only when you run an infected program or document. They can then be copied (duplicated) in other files, to support its extension (infection). At other times, attack, producing different effects. The virus is limited to display on the screen a message indicating their presence, and giving particular ideology or particular fondness of the programmer who created it.
