How to Totally uninstall WinAce software?

Hello guys,
I am having trouble uninstalling this software called WinAce. It was present on the computer when I purchased it and now I cannot get rid of it. I have deleted it and quarantined my system with the help of anti-virus, but this software keeps on appearing and reappearing on my computer. Please help me get rid of this pest-like software. Thanks a lot!
