This is actually funny when we use the term virus. It originally meant the bad agents, which attacked human beings and made them sick. Then this term was also used to describe problems created in computers and laptops. And now- even mobile phones are not spared of it.
Your mobile may be under severe threat if you are not implementing the right kind of protection systems. These threats usually get into your mobile when you download from any external source, through the internet.
Your bills may get higher, or your smart phone may start responding slower if you are attacked by these agents. These are commonly known as malware and spyware. Even your privacy may be threatened and you might lose valuable information too. Countering these threats is very important. In the next topic I will tell you how these threats can be prevented or eliminated.
