Now a days i am receiving lot of spam mails generated by my id to my id. I have Exchange 2003 Server and Outlook 2007 client. I scanned my laptop for viruses, spyware, malware but it is not infected. My observation is that even when my laptop is off and when i switch it on, in my mailbox i can see lot of spam mails which are generated by my id, sent time of these mails was when my laptop was switched off. Can anybody help me with a permanent solution to get rid of this problem ?
