Cheers for the reply.
AvastSvc.exe is starting keytool.exe at windows startup, i can see this with Process Explorer. Keytool.exe (from different java versions) becomes a child of the AvastSvc.exe node in the Process Explorer tree, which means avast is starting keytool.
I suspect/wild guess that it has something todo with ssl certificates (root?) avast uses.
Can't say much more about it.
