What is Malware? pt. 1 - The Annoying Kind

Malware, short for malicious software. It is an umbrella term used to refer to a variety of forms of hostile or intrusive software. Malware is defined by its malicious intent, acting against the requirements of the computer user, and does not include software that causes unintentional harm due to some deficiency. Some malware is destructive by design, others are more of a nuisance but should be seen as a gateway menace in that they may quietly steal data thus leaving the user exposed to further, more devastating, problems:
