Here is the software and instructions to clean a virus from your machine: Please note that the old password that a virus was using to send spam/virus emails with should no longer be used anywhere. If you are using the compromised passwords anywhere else, you should update all of those other accounts with unique passwords.
Best practice is to always use unique passwords for every account, and always change any passwords that you might have used or entered while a virus was present on your machine after you have removed the virus.
