The internet has become a very important part of our lives. We carry out all our important operations through internet. The world 
of web has given the luxury of a carrying out a lot of operations which previously required a lot of time. Most of us now carry out our banking operations on line. Pay bills online, book tickets for almost everything, all these transactions involve money and have other important information. If someone we don’t want gets an access of this information we might actually be ruined. Viruses’ malware are these miscreants from which every cyber user is scared of. These viruses’ are created by unethical hackers who have the intention gaining control over others information and sensitive data. The attacks over other people’s systems are generally done through internet. The malwares are sent through unidentified mails or mostly downloaded sites encrypted with the download material. These once downloaded on the persons system can act in two ways. One of the kind aims only to spoil the software’s if the system other type gains access over the information of the system user and pass it on to the creator of the viruses. These virus and malwares are of different types and are named differently on their types for example worms, Trojans etc. These viruses are often also created by the antivirus or protection software providing companies to speed up their sales. So, actually to blame who is responsible for the creation and spreading of these hacking devices is very ambiguous. They are also designed and created by the tech geeks who have no harmful intension but create these viruses and the malwares just to put their tech skills on test. These viruses are source of terror among the cyber users who carry out important and financially hefty transactions online. The key of being safe from these is to use a good antivirus and mainly being careful while surfing.
