I've scanned through it a few times and it seems to have been a virus. Amazingly, I have downloaded this "Flashget" before playing grand chase and after a day or two my computer was wrecked. I do not see flashget as secure.
Flashget=The download manager on grand chase's download page.
I have had Flashget for a long time now. I haven't had any virus's pop up.
I can give you proof. Go to google. Type in flashget virus and you will see results.
