In Outlook Express email client, there is a setting under "security option" stating "warn me when other applications try to send mail as me". Is that helping into knowing if my PC is sending spam or the like?.

No. Leave it set, but it only covers a now infrequently used technique where viruses would hijack Outlook Express for your address book. Current malware bypasses email programs completely, in which case that setting has no effect.

Just read this article about the now largest botnet in the world, Kraken.
I quote: "The so-called Kraken botnet has been spotted in at least 50 Fortune 500 companies and is undetectable in over 80 percent of machines running antivirus software. Kraken appears to be evading detection by a combination of clever obfuscation techniques, including regularly updating its binary code and structuring the code in such a way that hinders any static analysis."

Should I be worried?

Hi Leo,

We have implemented a new spam/virus filter at our work. It is setup so that if someone send us an email that is suspected spam or virus, the sender will recieve a reply email informaing them that their email did not make it to us.
Lately people have been sending us emails asking why they are recieving an email reply to an email that they never sent. I always direct them to this article as it clears up all the hassle of explaining to them that they might have a virus. After i direct them here I never hear from them again....so obviouly the points you mention at the start fix everything up!
Keep up the good work! (it makes my job easier!!)
