Things to be done to Secure Computer
Maintaining security software:

After installing is done, run the program (i.e., identity finder, a tool) that helps you search for, protect and dispose of personal data stored in your computer or external media.
Least privilege principle:
Principle of least privilege is an important concept in computer security and is also known as the principle of least authority. Least privilege means that you should provide the least authority necessary to perform its duties. That is, you should promote minimum information about the user profile on the computer, according to the necessity of the user’s job. By this, each part of the computer has only the privilege that is needed for its functioning and in this manner, even if a hacker access to that part, he will have only limited access instead of having whole access to the entire computer.
Updating and maintenance of current software:
The operating system you use must be secured. Keep your software updated whenever it is out of date by having latest service packs or packages. For example, you can install avast antivirus for the operating system Windows XP. It frequently gives you message for the updating of the software and you can easily come to know at what time it should be updated making your work easier.
