"Adware Alert" uninstall problems

I unfortunately installed Adware Alert as a spyware scanning program back in
February. I have since learned that it appears to be a corrupt anti-spyware
program. I tried uninstalling it, but when I do, it seems to corrupt my
operating system's startup. After uninstalling Adware Alert, I am prompted
to restart, but then my system gets caught in a loop, where it displays the
first few startup screens repeatedly and will not re-boot.

I have been able to get back in by hitting F8 during the startup and
manually selecting to start using the last known good configuration. I tried
starting in Safe Mode, but this did not work. Once I'm back in, I can do a
system restore to get it functioning again, but only if I restore it to when
Adware Alert was still installed.

I feel like I've been hijacked! How do I get this garbage off my computer
and still get it to operate correctly?
