SISUSBrg will attempt to change a protected regisrty key when the system restarts from a crash. Komodo's Defender+ will flag this. It doesn't seem to matter if you allow or block this activity. THe system will reboot and run normally.
I think it might do something, my PC has been slowed down recently due to a new HD put in and this could be related I believe... any info on this pls email me at
USB controller on WinXP.
sisusb.brg is not a virus or trojan, sometimes on laptop computers a usb port does not shut oof and discharges the battery, this file is supposed to correct this problem. Do not use it if you battery does not die when your laptop is swithed off as in my case it caused the discharge of the battery in off mode in three days.
