Update notification option over automatic updates

The one thing that always gets on my nerves with Trend Micro is the automatic updates. I understand why it needs to happen. But it makes the computer run super slow and gets in the way of things (like watching a movie where Windows Media Player and Windows itself will freeze up for a minute). And Trend Micro is the last thing one my mind when I wonder why my computer is acting up (I like to think the Anti Virus software won't give me any troubles 120% of the time)

I'd like there to be a notification saying that there are updates available rather than Trend Micro updating automatically. And then I can choose to update or not. Or if that's not possible, have Trend Micro automatically update when the computer is not too busy.
