huge annoying problem with explorer.exe freezing! help!
 

I have a huge problem, I posted on the daemon tools also but no reply so I will post it here since I really need help with it! Whenever I unmount an image from daemon tools and launch windows explorer or my computer it freezes and it's impossible to end task on it, the only thing to do is restart..I tried Alcohol 120% also but same problem! what could be the problem??
