A microbe is quite simply a micro-organism, ie too small to be seen by the naked eye. A virus is a microbe.

"Microbe" is a generic term used to describe microscopic organisms, including viruses, protozoa (amoebae) and bacteria. It's a bit like using the word "germ" to describe infectious diseases.

Viruses, on the other hand, are distinct entities. They are small obligate intracellular parasites which lack the ability to reproduce without the help of a plant, animal or bacterial cell. In essence, viruses are just infectious packets of genes which hijack cells and turn them into virus factories.

Yes in the media and general use words are always interchanged. Sterilant for example doesn't mean disinfectant. The latter kills a percentage of the microbial population and sterilant removes all viable mibrobial material. Important when dealing with surgical equipment for example.

I also hate when the media just totally gets it wrong. I am reminded of an article about BSE/vCJD when they had a picture of a "BSE Bacterium". Shockingly inaccurate when infact it is prions(proteinaceous infectious particles) that cause BSE. A similar size equivalent of mistaking an ant with a elephant (it maybe an even larger mistake than that).
