Why am i sending emails out ,i havnt

Sounds like you have been infected by an E-mail virus -- once infected it gains access to your address book and begins sending SPAM to everyone on your list (usually including a link that also infects their system once they open it !) -- First run through the Steps listed HERE then if you still are unable to clean the system go to the site linked below and follow their instructions.

IF you need help ridding the system of the problem HERE is a good site that will help just read through and follow the steps listed and they will examine all of the reports you send them and respond with detailed instructions on how to clean the system.

Once you get it cleaned you may want to contact the people in your address book and let them know if they received a message from you lately that it might have been infected so they should check their systems also if they opened any links included in any message from you. !!
