Hello Yossi. As mentioned earlier AVG Free Antivirus does not have Anti-Spam feature in it. I guess that the problem would be with your Outlook configuration. Please setup the email scanner in AVG by following the instructions mentioned in this link: http://www.avg.com/us-en/faq.num-3440 and check whether the issue persists.

Kummar, I disabled temporarely AVG and my inbox is still filled with the rejectsions,
 Can't AVG detect and remove the  virus on my laptop causing this SPAM?

I hvae AVG free version installed on my WIndows 7 Thinkpad x201 laptop.
From a day or 2 ago I receives in my Outook tones of rejected emails send from my acount.
It seems that virus attacked my laptop, I scanned the whole computer by AVG last day but nothing was found.

What should I do to clean it?

Hi Yossi, sorry to know that. Please check if the undelivered emails are sent to a particular sender or this happens to all your contacts. If it is a particular contact, please check if the sender's email address is correct. Also, please check if AVG is up to date in your computer. Thanks.
