What is a Virus/Spyware scanner and do I need one?

A virus scanner is software that scans select files to see if any characteristics about them match a list of known viruses in a database. Anyone who uses the internet or exchanges files with any other computer definitely needs a virus scanner!

Virus scanners can work in two modes, in the background or on demand. All virus scanners install by default in the background. When your computer starts, they begin scanning everything you and all your programs touch, to make sure no files you use contain a virus. This method is best for the average user, however the scanner is continuously using computer resources, most often scanning files that have never changed and don’t have a virus.

More professional users can turn off background scanning and only scan new incoming files upon receipt. This saves computing resources for your every day needs.

We have found one of the best scanners to be Grisoft AVG Anti Virus 8. It is fast, uses less computer resources, is one of the few scanners we’ve seen recover an already infected PC, and best of all: Free for personal use.
