Help Identify and Remove Web Browser Video Download Plugin

Hi;

Some time a go I installed some software to download Video from Web Pages such as You Tube so I could view them off line. I have no use for it now but every time I hover over embedded video on a web page in Safari or Chrome an annoying 'Download' button appears.

The software was (i think) iSkysoft Free YouTube Video Downloader in fact I just ** ered over a video and right clicked the mouse and selected 'Inspect Element' and in the script iSkysoft appears.

Any idea how to remove this software and stop the download button appearing?

Thanks

Should have done a bit more googling before posting..........found this thread: https://discussions.apple.com/thread/3589676

Installed iSkysoft again and followed the last post in the thread, preferences/extensions and both SAFARI and CHROME where installed. Clicked uninstall and hey presto, that annoying button disappeared.
