Tips to stay virus free
First of all, it is good to understand what a computer virus is. Traditionally a virus is a program that can replicate itself and spread from one computer to another. Viruses have now grown into many other nasty types including malware, adware, spyware, computer worms, Trojan horses, and rootkits just to name a few. Below is a brief description of each of these:
Malware is short for malicious software and is designed to disrupt or deny operation, gather private information, gain unauthorised access to a system and for other abusive behaviour.
Spyware is a type of malware that can be installed in computers and collects information. Usually spyware is installed secretly on the user’s computer and can be known to change computer settings resulting in slow connection speeds, changing home pages, key logging, loss of internet and redirection of internet traffic.
Computer worms are a self-replicating malware program, which uses computer networks to send copies of itself to other computers. These worms are usually spread due to security vulnerabilities and cause harm.
Trojan horses are software that appears to perform and function normally to a user, but steals information or harms the computer.
Rootkit is software that enables access to a computer while hiding this access from the user and administrators.
It is critical that all electronic devices be protected from this range of computer viruses – this means protecting not just your computer but also workstations, notebooks, servers, mobile phones, tablets, and most devices that have user input or connectivity including internet and memory cards.
