No viruses whatsoever detected on my computer (I’m really careful about it don’t worry).
EDIT: I think I found the source of the error message, I looked up in the task manager to see which process is relied to the error message and I found that it’s called “csrss.exe” that stands for “client/server run-time subsystem”, didn’t know what that really mean or what is the relationship with my error message but by searching deeply on the internet I found that someone has some equivalent problem with some software that he just installed on his computer and the problem was related to an external device that is a “multi-format card reader” that can be used to read SD cards etc…by pluggin them into this device that is plugged himself by a USB port in the computer. So I just tried tu unplugg this device that I’m not currently using and it seems that the error don’t show up anymore, I’ll see tomorrow when I’ll restart my computer if it really was the correct source of the problem.
EDIT 2: For those who might be interrested in which device it is and may have the same problem, my device is a
“Realtek Semiconductor Corp. RTS5111 Card Reader Controller (USB2.0-CRW)”
EDIT 3: I just tried to replug my device and I actually get the same kind of error with the one change that it’s not
“\Device\Harddisk4\DR4”
anymore but
“\Device\Harddisk4\DR11”
I assume that the " DR** " thing is random. So, problem solved !
Thanks for your help Jacky =)
