There are millions of Screensavers available on the Internet. Almost all of these can be downloaded and installed easily. These are usually categorized according to themes. Nature lovers can choose picturesque locations. Fish lovers can choose from different kinds of aquariums with multi-colored fish that are swishing through colored water. Those who really like adventure sports or aircraft can choose from a wide array of moving images and clips of death-defying stunts. Screensavers can also be slide shows that have various pictures of movie celebrities, sportspersons and politicians. However, some precautions need to be taken before downloading Screensavers. The most important one is that Screensavers must be downloaded from trusted sites. Its also always a good idea to scan Screensavers for viruses and other potentially dangerous elements, such as spyware and adware. If an anti-virus is already installed on the system, a right click enables a menu which provides for a scan with option. This option can be selected and left-clicked to check the selected download before double-clicking it and installing it. Sometimes Screensavers are extremely graphic-intensive. This means that they contain so many graphics that they are huge files. Huge files take a lot of space on the computer when they run, and make the computer work so much harder and so much faster than normal that the computer freezes. Then the computer needs to be restarted and all the unsaved information on the computer -- such as open files that were being worked on before the Screensaver was activated is lost. Some Screensavers also make the hard drive of the computer crash, causing irretrievable data loss. Therefore, it is important for users to download Screensavers that are compatible with the configuration of their computers. This means that the speed of the processor in the computer, and the free space on it, should be sufficient for the Screensaver to be downloaded, installed and run. Many users like to create their own Screensavers, often with the visuals and audio of their choice. Some software applications facilitate this. Out of these, some can be freely downloaded from the Internet. However, these should be downloaded only from trusted sites, and should be supported by the configuration of the users computer. Once downloaded, these should also be scanned for viruses and other common infections. When installed, these programs enable the user to combine images, video clips and audio clips to create a personalized Screensaver, sometimes even for circulation amongst friends and family. |
