What does VGrep do?
VGrep is a system produced in an attempt to clear up some of the confusion surrounding the naming of malware. It works by running scanners across a large collection of malicious files and parsing their output into a simple text database.
What it does not do
VGrep is not intended to be used to compare the detection rates of scanners. This is a more complex task, and is handled by Virus Bulletin's comparative reviews.
Neither can VGrep provide any information about a piece of malware, other than the various names for it. However, once you have found the correct name in VGrep, you will be able to find more information about that malware elsewhere.
Why do we need VGrep?
We need VGrep because, without the correct name, it may prove very difficult to access accurate information about a piece of malware and its effects.
VGrep was originally created by former Editor of Virus Bulletin Ian Whalley.
