this is the second time this has happened to me in a short period of time and I am hoping that somebody can help me.

Something is sending emails to all my hotmail contacts. The email:

Hey friend,
How are you doing recently? I’d like to introduce you a very good foreign trading online company and the website is www.ui-mall.com
It can offer you so many kinds of electronic products which you may be in need,such as laptops, gps, TV, cell phones, ps, MP3/4, motorcycles even several kinds of musical instruments and etc..
You can take some time to have a check ,there must be something you are interested in and you ‘d like to purchase .
The contacts:
XXXXXX
XXXXXX
Hoping you can enjoy your shopping from that company !
Regards

When I go to "Sent emails", I do see these emails there.

I attached the logs under the "Software" forum.

Is this a virus??

Please help!!

Thanks in advance,
Marzena
