I cannot turn it on using AIS with Outlook 2010.
Repair the installation from Add/Remove programs and restart your PC 
Thanks that fixed it. 
It turned itself back off again.
Strange… Working fine here till now : Maybe you should generate a log and send it to avast!?
Mine is still working fine. Just checked and Avast says it is running.

I did another repair and so far so good.
Sorry, we’ll fix it in the next version. You are actually lucky if you made it work with repair.
Drake… I must be really lucky, because the repair fixed mine, and it is still working.
Gregg
Repair fixed mine too - twice.
Just curious… Might reset to Factory Defaults (and Reboot) work as well?
And, can anyone confirm antispam is working after all?
I forwarded some junk from gmail to outlook express, and it isn’t marked. I don’t have contact list there, atm, even if auto-whitelist was switched on - supposed to be by default, but isn’t.
Side point maybe:
I notice the antispam ‘switch’ slides across the instant that box is opened - before repair, that is.
