There are many websites that offer free screensaver wallpaper for download. The 
question remains, though, are those screensavers safe? By downloading and installing free screensaver is any harm coming to your computer? This is a legitimate concern that must be addressed before anyone even think about installing screensaver for free.
There are some malware may come bundled with free screensaver wallpaper. This is basically be free from viruses, spyware, adware and toolbar. There are several options in this program, but in general they consider undesirable, if the user has a specific request for them. And from the list, the only thing that you would not even consider installing the toolbar user. But more on that later. 
Below is a brief summary of each type of malware that you want to avoid:
Viruses: This should be avoided because they may adversely harm your computer, often on the verge of losing data can not be eliminated. If you are afraid of living with the virus, just download software from trusted sites, where the program is tested and tested, such as Download.com. Download.com also use their own files, which means that the software can not be changed at a later date to include viruses.
Spyware: This program used to track and unethical spying on your online activities online. The data can then be sold to advertisers or to modify your browser and computer functions. Spyware is one of the worst kinds of software packages, and can be difficult to remove.
Adware: Adware little less scary than the spyware, but no less disturbing for the average computer user. Adware programs will continue to display the pop-ups and unwanted ads while browsing. Sometimes you may not even realize that you have adware if you see excessive pop-ups while surfing the normal (in which there are no pop-ups before).
Toolbar: Finally we have a toolbar that is a mixed basket. Some toolbars are actually quite useful, for example, Google Toolbar, or some of which offer enhanced entertainment, as a panel StumbleUpon. Thus, there is another toolbar, which is used as a means of displaying advertisements and is difficult to remove. Some unwanted toolbars come bundled with free screensaver wallpaper or software, often from the company of several "big names" are called. 
It is very important that you do your research before you download a screen saver. Read the Terms of Service and conditions of use on the site, as companies are obliged by law to inform the user that they will install.
Make sure you read the fine print. Not only that on the download page. Sometimes they say "No Spyware", but they said nothing about adware. Are you willing to put up with some (or many) of the ads for free screensaver wallpaper? Most people, of course, should not be. By James Lundeen
