What is a computer virus?

- It is vital to keep your internet security software up to date in order to provide the most complete protection. Thousands of new viruses are detected every day, to say nothing of the variants of new and existing ones. Each has a set of characteristics or ‘signatures’ that enable internet security software manufacturers to detect them and produce suitable updates.

A computer virus is a type of malicious software, or malware, that infects computers and corrupts their data and software. They are always the result of human activity. Because they are designed to replicate themselves by infecting other programs on a computer, they are termed "viruses".

- Computer viruses are designed to cause system disruption, significant operational issues, and data loss and leakage. They typically attach to an executable host file, resulting in the execution of their viral code when a file is opened. The code then spreads via networks, drives, file-sharing programs, or infected email attachments from the document or software to which it is attached. The way a computer virus performs is determined by the way it is coded. It could be as simple as a harmless prank, or it could be sophisticated, resulting in criminal activity and fraud.

 - While some viruses are limited to a single device, others spread across a network environment in search of other vulnerable hosts.



What is Spyware?


- Spyware is software installed on a computer system that is designed to collect information about the computer user often without their consent or knowledge. This information may result in so-called identity theft, or theft of valuable information (such as bank or credit card details) or proprietary business data.  These days, much of the current spyware is developed by organized crime rings, rather than opportunistic lone individuals and is installed by a virus or another form of malware






What are Rootkits?


- A rootkit is a type of malware designed to gain privileged access to a computer while hiding itself from the user and the operating system by, for example, compromising the communication channels within the OS. A rootkit can hide files, data, processes, and network ports, and can typically survive a system restart. This stealthy design enables the rootkit to escape detection by most anti-malware tools, which may be effective in detecting/removing malware-like viruses but are generally ineffective against rootkits.




How to Prevent virus infection ?


- Be extremely cautious when opening email attachments. It is best to avoid opening any attachments received from an unknown source. If you need to do so, you should first save the attachment to a folder on your computer, then open the appropriate application (such as Microsoft Word or Adobe Acrobat) yourself. If you use the program File menu to open the attachment manually, rather than double-clicking the file or allowing your email program to open it automatically, you are less likely to contract a virus.
