How many times suddenly you have a virus on your computer and you are certain that you did not surf the net anywhere where you should not, or downloaded a suspicious email or open an attachment to one? Perhaps your technical guy you said well "you must have done something like that."
You consider that the culprit might have been this free software program that you downloaded from many months ago? Well the fact is that increasingly more called free programs available on the internet, contain Trojan viruses of various shapes and sizes. It is of small files dropped on your computer during the installation of "that" free program, which seems to work so well and you like so much.
Trojan virus is not often activate immediately. It is programmed to wait until a particular time, sometimes lying dormant for several months prior to activation. In this way, it covers his tracks where you got it from. The virus then worked its magic, modify your files, messing with your registry settings and generally catastrophic on your system, so that finally your computer gets slower and more slowly, keeps freezing and abandoned eventually. And during this process, that the virus just sent all your passwords, banking information and other private information that you had on your computer to its author. In simple words its flight, but there is often not much you can do about it.
Another pain are programs that are added during Setup, such as toolbars, research assistants, and others. The big boys such as Yahoo and Google are all also shameless giving you these boring gifts as many small internet businesses. They cover giving you the possibility to check a box if you do not want their other things special. How many times have you forgotten that little check box and now are locked in research with Yahoo et al. Other surprises bit nastier in free programs are those that hijack your internet browser, so that whenever you arrive on a page that is not available, it springs into life giving all kinds of unwanted options. Or that he replaces each page fourth or fifth to travel with his oh so useful information.
Many free programs are also delivered with spyware who looks at your computer along and returns his master-sensitive information. Some can become so boring and almost impossible to remove, that the only solution is a complete cleaning of your hard disk and reinstall Windows. Familiar? Is it not better to buy a membership program or Web site and to ensure the cleanliness of the program, as the author is get properly rewarded for his work with your payment and did not need to resort to these vulgar tactics.
