Avast for 64-bit

I have windows vista OS 64-bit
plz give me link to download of Avast AV , 64-bit version if any.

There is no separate 64bit version. One installer contains both, 32bit and 64bit versions of avast!. So, whatever you do, you always have 32bit and 64bit program inside installer (which then automatically detects which one needs to be installed).

When will support Scanning Startup on 64-bit?

avast 5.1

nmb

thanks

when its planned to release ?

When it’s ready!
