SIS Graphic Cards – SISTRAY.EXE
SISTRAY.EXE places an icon in your system tray that can be used to quickly access settings for your Silicon Integrated Graphics Video card. Because you can access these same settings via Control Panel, it is not required. You can check for the latest drivers at http://download.sis.com.
Unfortunately, this file may also find it's way onto your system as part of the Prova Trojan. If you don't have an SIS video card, run your virus scanning software. If you have this trojan, sistray.exe will appear in your c:\windows\command folder. More info on the Prova Trojan can be found at http://securityresponse.symantec.com/avcenter/venc/data/trojan.prova.html.
