Nvidia Driver, causes no problems whatsoever on my system. If this file appears to be causing you problems, you have a configuration issue. try some different versions of the Detonator drivers, and see if you keep having problems   -=Milamber=-
nVidia Driver , if there is no nVidia graphics Card in your computer it might be a virus. I'm using a GeForce 3 Ti 200

nvsvc32.exe is a process that belongs to the NVIDIA graphics card drivers. This process should not be removed to ensure that your graphics card drivers is working properly.   Scott
May be possible to disable and still adjust settings for Antialiasing and VSync, which need to be disabled with Geoforce series cards and certain games.   Krul
NVidia driver. Disable to save some memory   open source
ive just installed these NVIDIA drivers from a purchased, clean, installation CD. When I restarted, my desktop was in 32 bit color mode, and this process was running. It seems to be completely harmless, and doesnt occupy many resources, or slow my system down by anything that I could even notice. I quit it, with no problem, and everything continued to run smoothly as it had before.   clean installer

this file should be located in windows\sytem32\ (on winXP). Needed to run certain video games, if you have an NVidea card, or if you want to overclock your carm or use other special features. If it crushes your pc's preformance, it's most likely NOT the driver.  See also: Link   Namnatulco

it depends on what your system is actually. i have 2gb of ram, w/6600 GT, and its always at a steady 3,966K, and 00 CPU. I looked at the hex for this and (at least, the one on my computer) found it isnt the virus w/same name. this is used by Nvidia cards, especially if you use a TV Tuner (it helps accelerate the FRAME/DRAW per sec w/good quality). however, you should disable this if you dont have any Nvidia cards or no longer have one. It can be safely disabled on most systems, and can even cause some systems to hang (noted in about 6 comments above). basically, use this if you only need to!   phrostwave
Nvidia driver! No need to wary, no need to kill!   Vir
i've noticed that "nvsvc32.exe" comes with nvidia NTUNE utilities, if u move it to quarantine, u wont be able to use some of Ntune features, like overcloking.   ChaoSs
Nvidia driver service, is in tasklist.   WallyBee
I just built a new computer, and installed 2 NEW Nvidia Sli 7800 GTs. The app came on both installation disks, and I would never Disable it, since it allows for more advanced control over the card. It uses 2,000k, but I have 250G of HD space, so it doesn't bother me at all. The only reason i would disable or uninstall it is if I didn't own an Nvidia GPU, or if I didn't know how to adjust advanced settings. Honestly, I think anyone with a problem either doesn't realize their computer is out of date and slow to begin with, or you're just not using the control panel correctly.   QA-Game Tester
Looks like I'm not the only one who's seeing this program eating up memory and CPU like it's candy... This one ran background for 2 years before I ever had this problem with it. Now, when running the processes "spoolsv.exe" and "csrss.exe" are using all the resources, but killing the app with Security Task Manager(R) stops all of this traffic.   Brando
After download latest nVidia drivers this service continuously uses up to 25% cpu and causes either or both csrss & spoolsv to use 25% cpu   Glen

As everybody says, it's just an NVIDIA add-in driver or service, put there to make certain (seldom-used) functions available from the Windows Desktop.   Travis
Usually a harmless 15ish megs of ram used, but some times starts to use 10-20% prosessing power when switching resolusions or enable/disableing multi monitors. it usually doesnt stop using the resorces for a long while.   AgentIce

Looks like an nvidia driver, has done no harm for me, so I do nothing to it. I think it helps the graphics card work properly so im not messing with it.   Jake
ItIts a worm hide itself in some programs, It even disable the antivirus, stops the Firewall until u terminate it in Command prompt. It runs well in Windows Explorer   Bildad
Halted by Windows DEP - may be old version (91.31)? Machine has been constantly and inexplicably rebooting when working with images and video during the past several weeks. Don't know if this is part of the problem, but if it's an unneccessary tool, I can experiment doing without it. NVIDIA GForce utilities still seem to work although it is not loaded and working.   TexasDukester

NVIDIA Component , disable it if you notice slow system shutdowns/startups. DO NOT disable it if you override your refresh rates in OpenGL games. D3D works fine through dxdiag or game options.   rififis
Somehow caused cssrs.exe to use up 50% CPU time with nvsvc32.exe using the other half.   RNA
it slows my pc, it hasnt been there from when i put geforce in.it appeared wen i installd something with NORTON on it, and i cant get rid of it   Cat
Keep if you overclock nvidia, otherwise dump it.   wood
If you're having trouble with this file and you don't even have an NVIDIA gpu, then it's obviously a virus. Get rid of it. There will be NO network traffic coming from this executable program, if there is, DELETE.   Howard D.

This is not the nvidia driver graphics driver, it's the nvidia driver helper service is a utility that can be used by staff at nvidia corp. to access your pc and monitor performance of graphics card drivers etc... It does have a genuine purpose, unfortunately it can be used as a backdoor by someone with the right knowledge... disable it, disable it, DISABLE IT! It has no effect whatsoever on your system with regards to performance if you disable it. I know enough to keep this turned off, the only time you will ever need to use it yourself is if you wish to override your refresh rate...  See also: Link   someone in the know

VIRUS! I don't have nvidia graphic card and my AV detected Worm within this file.  
I am calling it neutral because it could be legit. But in my case it is not. The process is new to my PC that is ATI equiped. I end the task and my PC stops trying to connect to sites on its own. All the sites it was trying to connect to are listed under the "more info" tab in the link below(a trojan warning from Sophos, whoever they are. The trojan is just using the process as a gateway. It is possible that the process is original to the OS as the manufacturer uses both ATI and Nvidia products. Also in my case there is no sevice to match it.  See also: Link   RAQ

comes with nvidia geforce drivers  
Valid NVIDIA graphics card prog. Should be harmless, but also non-essential. Some are complaining that it shows up as a virus on their machines - obviously, a virus can be named anything, as it VERY CLEARLY states above. If you don't have an NVIDIA card and you have no idea where you got nvsvc32.exe from, then it is entirely possible that you have a virus masking itself as an otherwise legit program. You did not get this virus from NVIDIA, you picked it up somewhere else. So stop trying to scare legitimate NVIDIA users.   D
will it seem word for NVIDIA but id you dont use NVIDIA software or any NVIDIA graphic card then it must be a virus worm or a tool like RAT tool   mhed2002
