have just finished trying to get my nephews laptop to work
it turned up with the wife ,
no charger
no external hdd to save college work to
found out it was a fake antispyware program
http://trojan-killer.net/internet-antivirus-2011-fake-anti-spyware-application-how-to-get-rid-of-internet-antivirus-2011-rogue/ha ha 20 mins and its gone.
boot up
msconfig
straight away ( before this program kills the ability to use it)
disable all entries at start up
reboot.
look for a file ( unknown name in list ) stored in your user (name ) temp file.
look for that file (named k ---- something ).te file name just doesn't look right
delete it.
reboot and thats it.
seems easy , but worked for me on his vista lappy.
