windows xp - Can Microsoft Security Essentials Signature Update Notifications be Avoided?

I have my Windows Automatic Updates set to "Notify me but don't automatically download or install them.".

However, if I install Microsoft Security Essentials, can I have the daily virus signatures downloaded and applied without being prompted each time by Windows Update?

I like to have control of installing other general Windows Updates, but would prefer not to have to be prompted for the signature definitions that I expect to have applied every day (would get a bit tedious) - these can just be installed without any prompt from Windows Update (if this is possible?).

Using XP Home SP 3. Just wanted to check this over before deciding whether or not to go for Microsoft Security Essentials.

Answer

I recently installed Microsoft Security Essentials. I have Windows Automatic Updates set to "Notify me but don't automatically download or install them.", however, I can confirm that the virus/spyware definitions are still updated silently (i.e. without prompting), on a daily basis. Great - as this is the behaviour that I was hoping for.
