I have a Acer Netbook which is currently dual booting into Xp and android.

I have never used Android before on a Netbook etc, so not sure what i need to know.

Do i need Anti-Virus running on it?

Any key issues i should be aware of?

And is it jus ta case of deleting XP and putting Windows 7 on to retain Dual booting with both of them?

Many thanks
