i agree, web cam antonyclark
anyway it takes lots of system resources YK SONG
Some kind of driver or software for webcam. In bad cases takes up to 95% of CPU time. Ali
webcam malware bran kop
I think it has something to do with webcam or PCI RAID controller card... noticed it after I installed both. However once my system goes into screen saver mode, can't get back to desktop normally and when I do VM303_STI is taking up 99 percent of processor time. Shutting it down from processes tree doesn't really effect my system that much. Haven't been able to trace its purpose and or utility. Asif Attique
Its the driver for my webby but its suppiciosuly called bigdog303 on msconfig
it hogs CPU using 99% at all times i banned process and computer faster and ebcam still works

When editing videos this file sometimes locks up cpu to 99% and consumes up to 300 MB memory. I dont know if that is a bug but it happens more often than not
Yep, cheapo webcam app Gregorious I
if you have a Leadtek Winfast TV2000XP Expert TV tuner, you may get the error "Cannot preview video stream". See the site I've listed or remove the file from startup.  See also: Link Mark Lewis
i think it indeed is dangerous... and i sure it comes from webcam... in my case too it came from USB webcam called PC camera. sameer rajimwale
I delited it and now I have no disturbing error window coming on screen alex
Comes with webcam, takes up resources of pc - therefore lags it. Bugs some applications Focius

The tool crashes at booting up Windows XP. Chris
from A4 tech webcam, locks up cpu to 50%, I blocked them. pipipi314
Because of this file my TV Tunner does not work! It may be a webcam driver process but I have to kill it before watching TV. nelusan

Came with a Webcam, Apparently its required to use it but i've been hearing things about it. I think it might be smarter just to get a webcam that doesnt give you a potentially adware/spyware application. (Also when i boot up my webcam which is now not working theres weird classical music playing for about 1-4 minutes) Donny
THE FIX !!! It's a TSR proccess called VM303_STI that is launched at startup belonging to A4 tech webcam. To stop it: start menu - run - type "msconfig" (ok) - goto Startup - search for "VM303_STI" - uncheck it - ok - restart - all done king
I haven't installed any web camera on my PC, but vm303_sti.exe is running on my PC somehow. silver
windows 7 - crashed hard drives and lags all time - Uninstall it or find better driver if it is fixed
It is web cam SW (I got this error message after installing Logitech WebCam)
