Why does Twain.dll Client’s 32-Bit Thunking Server keep loading on my PC? It is eating my memory up and not enabling me to efficiently work? Any help would be greatly appreciated! 🙂
KeithHi Keith –
What’s the name of the .exe, and what folder is it in? (Task Manager can tell you this)
What exactly is the symptom or symptoms?What operating system are you running?
Have you changed anything on this computer recently: New hardware, new software installed, new drivers, some kind of clean-up?
I’ve never heard of this problem (in 15 or so years of working with TWAIN) but I see it reported on the web, so I believe you 8)
But I can’t think of any reason for this program to be using CPU cycles or using up significant memory. Especially if you are not using a scanner.
So my first thought is, maybe this is a viral infection. Are you running a good anti-virus, and have you scanned that particular .exe?-spike _/_
It was a Twunk.32.exe file. They kept loading and loading. Sometimes I has as many as 200 of these files humming along.
Crazy thing is, it’s not doing it anymore!! The only thing I can think of is that it may have been a virus, and NOD 32 took care of it. Now I’m using some 7=8% of resources (normal)
Thanks for answering! It was a little unsettling!

Well, glad you are running a good antivirus, and that the problem is gone.
If you meant to type that, Twunk.32.exe (with two periods) then I’d say definitely it was a virus – I don’t think there is any legitimate file with that name.
If that was a typo and your file was really named twunk_32.exe, then that is the name of a legitimate file distributed as part of TWAIN… but that file is sometimes hijacked or replaced by various malware: That is, same name, different, bad code inside. The legitimate TWAIN file should never run more than one copy, or use up significant memory or CPU, or be running at all unless you are doing TWAIN scanning.
Good luck, happy and safe computing 8)
Definitely a virus involved. The process twunk_32.exe (Twain.dll Client’s 32-Bit Thunking Server) was running several times with massive cpu usage. Avast was blocking sites without me using a browser and when I was browsing links would be redirected. Avast let it in and a full scan found some other(?) problems but no fix. Installed Malwarebytes and found it.
