I've had DivX on my Mac for quite a while now, I can't remember exactly how long but I once thought I needed it. However, when an 'updates available' notification from it popped up on my screen when I started up my Mac one day, I realised I never used it, so decided to uninstall it.

After searching for ages, I finally found a DivX folder in Finder > Library > Application Support, so I completely deleted it. However, sometimes when I start up my Mac, I still get the notification telling me there is an update available for it.

I can't find any trace of it anywhere else in my Mac, no way to uninstall it, and even though it's not essential for me to uninstall it I simply don't want it any more and it's becoming rather annoying.

Any help would be appreciated.
