I don't know if this is a virus or not, but somehow registrybooster got installed on a toshiba w7 laptop (not mine). It was causing severe system slowdown so i stopped it in MSCONFIG. It started again anyway. So i uninstalled it -- now the system boots to a black screen. It goes thru the boot process but when it is suppose to present the desktop, the screen is black with a blinking cursor.
any known fix other than a reinstall of OS???????????
