Omiga plus isn't a virus, it's one of the products of a company that apparently goes by the name of "Taiwan Shui Mu Chih Ching Technology Limited". This product is unpopular with users - ratings give it 1 star out of 5.
"Omiga Plus is a program that helps you organize your desktop and hide your icons when they're not in use"

The malwaretips advice is pretty sound but be aware that if Omiga Plus is present on a system then there will probably be other unwanted programs as well.
it was hard to remove, my chrome got hanged up with omiga, tried a lot of user settings, changed my default search engine to google, set my tabs page to google.com but it just didn't work...
Had to re-install chrome to get rid of it...couldn't be happier........its like a virus!
