Disk Defragmenter
The memory of a computer is divided into small blocks.
The files are stored in continuous blocks of space on the
hard disk. When a file is deleted from the computer, a part
of that space becomes free. When a new file is saved on
the computer, some part of it is saved on the first available free space in the memory.
After some time, the files get stored in various fragments which slows down the speed of
the computer. The Disk defragmenter organises the fragments of files into continuous
blocks to improve the performance of the computer.
Virus Scanner
It is used to scan the computer for viruses among files and
folders. It scans the disk each time you insert it into a computer
or whenever the computer is booted. It is also called antivirus
software. Quick Heal, Norton, etc. are examples of this
software.
