September 2011  Antivirus Software - Should I have it and if so
which one should I have?  You need some sort of antivirus
software if your computer is connected to the internet (or even
if it’s not, although problems are less likely). This is a big
topic but I’ll try to be as brief as possible. Firstly we need
to understand the difference between the terms malware, virus,
worm, adware, Trojan (horse), and spyware.  ·     Malware -
Short for malicious software - This is the general term covering
virus, spyware, worm and all of the others.  ·    Virus - A
small program designed to change the way a computer operates
without the permission of the owner/user. Viruses run by
themselves and can cause a variety of things to happen and are
designed to replicate and spread from one computer system to
another. Some viruses are designed to cause as much damage as
possible, e.g.  deleting the entire contents of the hard drive
or changing the contents of your files. O
