Manual or resumable update downloads

Is there any way to manually update the virus database, or resume it once it’s started updating?

I’m currently based in Mozambique where the connection is good, but not great and having recently re-installed CIS, my connection is not stable enough to get through 100MB+ (?!) of database updates, so I have to start again!
