BleepingComputer.com: Postmaster/mailer-daemon Messages From Addresses Not Emailed

For the past 3-4 weeks I have received 30-40 messages everyday from Postmasters and MAILER-DAEMON informing me that my email to the recipient has been blocked or cannot be delivered. These messages appear to be coming from sites around the world. The issue is that I have not emailed them in the first place. It appears as though somebody has been using my email address

I have two email addresses but it is only the @freeserve.co.uk address that is affected. I am loathed to ditch the freeserve address as so many legitimate users use it. Has this email address been hijacked - if so what can be done?

Apparently your email adress has been found by a socalled spambot, some sort internet crawler which scans forums for email adresses and will use it to send out spam. If you want to be sure of malware issues

In normal mode, run an online antivirus check from at least two and preferably three of the following sites
BitDefender
Computer Associates Online Virus Scan
Panda's ActiveScan
Trend Micro Housecall
Windows Live Safety Center Free Online Scan
This scanner from Trend does not require an Active X to run.
