I was a little worried when I saw it only had two comments on here when I checked. Anyway this is Virus free as far as I can tell and It was a much better program than I had hoped.
Lightweight and highly customizable. :)
Good free open source software for screenshots. Works good.
Greenshot allows quick creation of screenshots, easy annotation, highlighting and obfuscating using the built-in image editor and sending the screenshot to a file, the clipboard, a printer or as e-mail attachment.
