This "Ncasespy" is not dangerous.
It doesn't infect your complete pc, and i doesn't delete or mess up system settings or files.
There is no need to "lose everything" when having this malware
just run ad-aware or spybot (both freeware) and your clean for 90 %.
just clean up the registery and .temp files afterwards for leftovers.
ad-ware & spyware just make your pc slow / compromise your privacy (little) and eat up your bandwith. nothing more, nothing less.
