Have you been able to figure this out? I have been getting this a lot. I’m on a new machine, it’s the Microsoft Surface Pro so it’s only 2 weeks old. Checking the event log, this has been happening since I got the machine. It seems to happen quite often.
I too have this. But I am not yet sure it’s related to Avast. Since I had Avast when I upgraded from Windows 7 to Windows 8. My event viewer didn’t have this before 2/15/2013 when I did the upgrade. But I hear this is a new event ID specifically for Windows 8. So that makes sense. Also. I did fully remove and reinstall Avast on 2/15/2013 when I did the upgrade.
I get these events randomly in bursts since Windows 8. I also have the issue where Network Shield does not work. And when it does/did work, it was causing massive slow downs in all web browsers and often would cause me to lose the ability to browse the internet at all. Yet LAN shares would continue to work. But I will post that in another thread.
Still, I am not convinced yet that the 4797 is because of Avast. I have another Win8 system with Avast to check on. And that system I can try removing Avast to see if it makes a difference.
Well, now I am on Avast 8.0.1482 on my main system. And the Network Shield works again. Going to see if the Event ID 4797 keeps happening. I also want to see if this event happens on my other Windows 8 system, and if it does; remove Avast from that system to see if it has any affect. I don’t think it will.

Funny thing…sass.exe on a websearch says its a trojan from like 5 years ago. If that is the case then why didn’t avast catch it? I’m guessing it’s not a Funsta trojan…
By the way, I fixed my ATIerecord issue. I downloaded the latest drives from AMD. Uninistalled Catalyst from the Control Panel - programs and then uninstalled the driver under display adapters in the Control Panel - Device Manager. Rebooted and reinstalled fresh drivers (via the catalyst all in one…i actually set mine to winxp service pack 3 compatibility) and the ATIerecord stopped calling errors every 15 seconds. Haven’t seen any since doing this.
I have Nvidia cards in the systems with my 4797 events. Glad you found a fix for your issue, but it sounds like it’s not the same issue. Also, I didn’t see you mention if you have Windows 8 or not. If you are not running Windows 8, then you certainly did not have the same issue as Event ID 4797 “An attempt was made to query the existence of a blank password for an account.” is new and unique to Windows 8 and is not in Windows 7 and lower. (not speaking of Server OSes).
I also get Events 4624 4634 4672.
I have uninstalled Avast from another Windows 8 PC last night. So far I don’t have the 4797 events. But those were and on and off again event. So I will wait longer. But I am still getting the 4624, 4634, and 4672 events.
As for the systems I upgraded to Avast 8, my Windows 8 system with Avast 8 still had the 4797 event. So overall I am still not convinced it’s related to Avast.
I have never figured it out. I have seen it on every copy of windows 8. so even on surface now huh?
Micro$oft won’t answer the question in their own forums…
Google it and you will see i have been trying…
It’s not related to Avast…
I agree. I still haven’t seen anything that implies it’s Avast. I only started posting here since the questions was asked by the OP. On my test system I removed Avast and the 4797 still occurs. I am going to check out other forums now about this.
