After I updated to version 4.6.603 Pro, the Avast stopped auto-update of iVAS again. I have push updates with email notifications. I am getting only emails but Avast Pro just sit quiet not updating itself. I have mannually update iVAS and maual updates are OK. To verify if this is the case, I intentionally waited for two days after receiving a push update email.

Internet connection type: DSL 24x7x365

My Avast Update settings:
[Update (Basic)]
Virus database: Automatic
Program: Ask when update is available

[iVAS details]
Runnign mode: Normal
Push iVAS:
Enable
Add information about performed action into email

[Update (Connections)]
None was checked

With the above settings, iVAS update was working flawlessly till the last version prior to version 4.6.603. And I have never modified the above settings.

Is anyone else experiencing the same problem in particular with Avast 4.6.603? Is this problem uniquely related to version 4.6.603?
