Startup Defender is a small program that sits in your Windows
tray and constantly monitors the startup locations on your
PC. If a program tries to write itself into any startup
location Startup Defender will popup a windows and ask if the
program is allowed to place itself to start automatically
with Windows. Also you can disable/enable any programs that
are currently installed to startup auotmatically. If there is
an entry you are not sure what it is then you can Google it
to see if it is needed or even harmful and choose if you want
it to load at startup or not. For the annoying programs that
try to repeatedly place themselves in the autorun for Windows
you can click the auto block so that Startup Defender stops
them with out you having to bother with them any more.
