Usually majority of PC user are more intend towards using an antivirus program to protect their computer. Even I do believe that it is a necessity to have an antivirus since it provides a real time protection to their system against viruses and spyware. Viruses and spyware are a kind of malicious software ( malware ) which are uninvited, destructive and intrusive. Such malware may enter into a computer through website visits, downloads, email attachments or installation of unverified applications. In the event of malware attack, Antivirus prevents, detect and remove them from entering into system. The malware counts are on the rise day by day and Antivirus developer are trying very hard to track new malwares and create an anti code to counteract such threats.


Firewall is a computer program which can either be hardware based or software based. It helps to create a secure network preventing unsecured and suspicious data to enter computer from external network. Firewall has the established rule set within it which determine whether to allow incoming and outgoing network traffic or not. A firewall act as a shield between internal network which is assumed to be secure and trusted and external network like internet which is assumed to be unsecure and untrusted. It helps in preventing unauthorized access to the system.

Encryption Software

Encryption software is an utility which transform data into an encrypted code which cannot be readable unless someone has the key to the algorithm used to decrypt it. Security of data including e-mail, transaction specifics, and networks is facilitated by means of encryption software. Its cutting edge technology and techniques helps to preserve the integrity of the data from the ever-growing threats of disease attacks and adware programs that pass on the Internet.

Backup Software

Backup software is an utility which enables to create the backup of all the data, file, folder, application and even whole of operating system to an external source. Although this category cannot be regarded as the main stream security product but still it can play a valuable part for an user to protect PC data and application. There have been instances where some threats are able to bypass the security layer created by the above mentioned products. In such circumstances all the data and applications becomes vulnerable to malware attack which could lead to loss or misuse of data. This is where the backup software comes to the rescue. Hence this utility also plays its part in creating an added layer of security for data and applications.


Although there are endless number of security product which are not included in this article. But as a general user, bundle of above product would definitely create a great security package. Its just an overview of most recommended product across.

They provide convenient ways to organize the home, pay bills, search for information, study, pay attention to music and even watch shows. An innovative strategy to complete all of these tasks is by using a notebook. These pc’s are mobile ones, small, strong and lightweight.
