Antivirus Security Pro - won't allow Safe Mode, Regedit or msconfig

A friend brought me a computer because Anitvirus Security Pro would keep running on his moms laptop. I have had probably 5 different computers that have had this on them and have been able to clean them but this one is really a beast.

His system is running Win 7 and he tried a number of things before bringing it to me with no luck.

I printed off the Anitvirus Security Pro Removal instructions from this site but the laptop is not allowing the system to boot in Safe Mode and It will also not allow access to Regedit or MSCONFIG.

Any suggestions on getting control of the system back?

Thanks

John
