If you were hijacked there's a big chance your system is floating with rootkits
1) do a complete format (yes, home and everything) - painful, but safe
2) install ubuntu on clean partitions
3) don't use wifi
4) change all your passwords, email and user login password
5) System > administration > software sources > Updates > check "install security updates without confirmation"
6) If you have other operating systems on your machine, like Windows, I suggest a checkup with several antivirus products, or even complete format/install
Doing one of these is not an option, do all of the above
Here's a good password-maker:
Code:
sudo apt-get install apg
apg
