"Suspicious operation" from SETIFACE.DLL

Avast Free Antivirus / Premium Security

When I start Firefox 1.0.7, I get a message:

Standard Shield detected suspicious operation.
…AVAST4\SETUP\SETIFACE.DLL

It appears that any of YES - NO - IGNORE gets me past this and everything is fine afterwards, but how do I stop this popup in the first place?

I don’t think it has anything to do with Firefox, but I guess you enabled some Behavior Blocker features. So, go to Standard Shield configuration and check the “Blocker” page; I guess you have the “Open file for writing” event checked (so uncheck it).

Don’t know if I set that box or it installed that way, but unchecking it solved it.

Thanks!

By default (see image) they are no blocking actions set.
