What I'm saying is it's most likely unrelated to FF4 since it's being used in the winlogon process. Uninstalling and reinstalling might fix it temporarily but something is altering your system in a bad way. You need to rule out malware first.
Have you downloaded and installed anything recently that wasn't from a retailer?
You are right. I need to find the process doing it first.
It happened first time after installing EASEUS Todo Back up installation. I uninstalled it though (no support for GPT Disks).
All my programs are safe downloads from the sites.
I have remote control and network programs, but they are safe.
I have steam. I play it online, but I don't think it can cause this.
My firewall is set to inform me any in/out activity for every application to take permission from me, and also set to inform me for changing any process to take permission from me.
I ran a full scan, but couldn't find anything related.
When it appears next time, I will try to find the process it is related with.
I am dealing with lots of different softwares, and also trying different softwares for my needs, but all my downloads are from the original sites or links from the original sites of the softwares. I checked both x86 and x64 Program Files folders and couldn't find any file or folder suspicious, but maybe I missed or this process is located another place, but I know all the programs installed on my computer (I uninstalled several programs I wasn't using).
I will try to do different stuff next time it appears and will inform (Not every restart it is happening, but even happening just sometimes is enough to annoy, and enough to know that there is a process going on that I don't know about).
Can it be a FF plug-in such as "close tabs to the right"?
But what does it have to do with winlogon.exe?
Anyway, I will inform...
Process Explorer might help
Process Monitor might also help. It take some learning of the app, but if there is some rouge process that runs intermittently, this could help find it. However, there is no way of knowing if there is one until you can identify what is really happening. It's kinda a shot in the dark though at this point. But, still useful.
The process is csrss.exe.
When I right click it and select properties, nothing is coming up (no windows is appearing, nothing is happening).
When I click Open file Location, nothing is happening either.
Username field is empty too.
csrss.exe = Client Server Runtime Process
It is a valid system file, however, it can be taken over by a trojan apparently
I am not trying to imply that you have a virus, but just telling you what that process it.
Scan with Eset Online scanner and see what it finds.
