Sadly i've installed this also.
unistalled it already. But i'm afraid it left something in my machine. Does anyone know what installed? or know how to analyze it? Can't format my Computer :\
Aside from the reformat option, there isn't much else you can do aside from using antivirus and/or antimalware scanners...
The Bleeping Computer forums have a lot of useful resources and links to a lot of free tools that you can use.
