JottiQ is a tool that makes it more convenient to use Jotti's malware scan, which is an online service optimized for one-by-one scanning of files you do not trust.

Its purpose is that of an investigative tool, for when you do not trust a file you came across but your current security software seems to think it is as harmless a file as they come. It is not meant to replace your virus scanner, nor is it meant to scan the heaps and heaps of nasty things that float around on your computer because you are too cheap/lazy/picky to get software that is meant for that purpose.
