A virus is a piece of code that has the
ability to spread through normal computer programs. Viruses wreak havoc by

other normal programs. A virus attack affects all applications in your device
which may cause your data to be wiped out.

self-sufficient. Worms reproduce themselves numerous times hence their ability
to spread through computer networks.
A trojan is a program that cannot activate or
reproduce itself. For that reason, it poses as a program that would be
beneficial. Once you fall for the trick and activate the program, it spreads
throughout the device and causes damage to normal programs.
Spyware is a software program that installs
