I've developed a program which can be used to help check if a program is
spyware or malware. It can record what changes are made to your filesystem
and registry when a program is run or installed. It's already preconfigured
to warn you if certain changes are made to the registry - and this is easily
configurable.

---InstallSpy Description---

Track any and all changes to the registry and file system, and also record
all shell notification events (e.g. media inserted), when a program is
installed, uninstalled, or run. This can warn you of programs trying to
install new services, programs that are set to run on reboot, changes to
your home page, etc. It's a highly configurable program that allows you to
catch any change to your system. Filtering lets you zoom down to the details
that are most important to you. Easy installation, comprehensive help file.

---Systems Supported---

InstallSpy does *not* work on Windows 95, 98, 98SE, or ME.
It must be used on Windows 2003, XP, 2000, NT 4, or NT 3.51 (SP3)
