About spam....

[NiKe]

Greetings!

Lately I'd been receiving emails which keeps telling me the address I mailed to is not valid and apparently I didn't send those mails. It turns out those mail are spams and since I don't know where they're from I have no idea how to block them...

Anyone can give me a hand? ???

Could you post your HijackThis log (http://www.tomcoyote.org/hjt/)
Download, Unzip and run HijackTHis, Then click Scan > Save log, save the log as a .txt file and copy & paste its content into your next post.
Don´t fix anything yet. Most of what it finds is harmless.
I just want to check that it isn´t anything that is actually being sent from your computer without your knowledge.
