And why do you suspect a infection ?
What OS/SP ?

https://en.wikipedia.org/wiki/Client/Server_Runtime_Subsystem

then when i run eset online it hangs after 3hours
and when i run gmer it displays :
thread c:\windows\system32\csrss.exe and it hangs too

i suspect malware…

i have now gmer already open with one line
thus the tread line with csrss.exe and when i rhight clic
i have the light option :

remove signed
remove duplicate
find3m
option
about

Do you even know what gmer does ?

And at what point (folder/file) does eset hangs ? (check the log file)

And again… What OS/SP ?
