[paul collins]

Binary package hint: firefox

CD-Rom Ubuntu 10.10 ISo
Tried another 5 times since yesterday to do full migration to ubuntu 10.10 with this CD-ROM
A local attacker has exploited my system and gained my root privleges
Every time i finish download to full migration, iam told to reboot, ON REBOOT =No Ubuntu 10.10
Last time after reboot Ubuntu 10.10 opened ,but i was unable to find right Username+Password I tried for hours different combernations but unable to open
What i would like is ALL old pragrames deleted and a fresh OSS Ubuntu 10.10 installed = No sharing my computer
PLEASE can someone Help me get rid of my local attacker
Thankyou. Paul
