Like Additional Benfits of the Home Edition, Bud Have Anti-Virus Program

[Referee06]

I like the additional benefits of the Home Edition, but already have a anti-virus program that I like. Can I buy the Home Edition without the anti-virus?

I don't believe so,no.I don't see that anywhere on the website.
But you could disable live protection:

If you have another antivirus engine running you can choose to disable the one integrated into Spybot +AV.

And this is from the help file:

Live Protection
Live Protection scans every application before it even gets started, allowing to block malicious processes before they start.

If you want to disable Live Protection, you can right-click the Spybot icon in the Tray area next to the system clock, and uncheck the Live Protection entry. As an alternative, you can open Settings, make sure all tabs are shown (see Advanced checkbox), and check the options on the Live Protection tab. In this place you'll also find further options.
