Windows Vista / XP Security Tips
Don't install unknown programs
The computer industry has evolved so much that today we have a unlimited amount of programs to choose from. You are the one who decides whether a program is worth keeping or not, it's important to take into account a few things like functions, features and user interface to determine if a program suites your needs or if it doesn't. One always needs to be cautitious when installing programs that he or she might not need because they are simply testing out the program and seeing if its worth keeping or not, because all programs install registry files that usually aren't easily removed when you uninstall a program you no longer want on your system.
It's also important to watch out when installing software because their is alot of software that comes with additional add-ons like toolbars. You should always check to make sure that when your installing a program you should uncheck the box that ask you to install additional software or add-ons like toolbars or other programs that you might not want or need. So remember to always be on the look out for add-ons that might come with the original software before you click that "Next" button.
