A lot of people have been complaining about a bug in the SuperAntiSpyware
program. It pops up saying that there was a new program added to your
startup and wants you to do a scan. The solution is to uncheck the option to
check the startup programs. That might be what you're experiencing too.
You should really have an anti-virus program along with Super Anti-Spyware. Usually SAS will run automatically in the background and update automatically.
Hope this helps.
