URLs sent from Contacts who are offline via Windows Live Messenger 8.1

Hi,

I'm receiving urls from some of my Contacts (3 so far) who were offline,
could this be due to virus activity (somewhere)? My computer is Virus
/Malware free and I have a firewall installed.

I'm using AVG, Comodo and Ad-Aware 2007 software.

This started a few of days ago.

Many thanks in advance

Matt U.K.
