About the order
It would not matter the order you install the AV and firewall as the computer is not connected to the internet until AFTER all ten steps are done.
I ALWAYS do the AV, then the spyware software. Then I RUN BOTH.
After the scans are done, then I reboot and continue very identical to that list.
After all updates and restore points are done, I defrag then reboot.
Then the FIRST thing I do after I am live, is to apply any MS updates.
Software firewall AND router are strongly recommened, with a clear understanding that the computer will be toast if they don't.
If they chose not to follow this advice, I have no problem six months later charging another $120 to wipe and reload the system.
