Messenger virus plagues Finland

There is a messenger virus in the wild now in Finland. It will try to get user to open a picture in strange-looking web site. But that picture is actually malware installer. After installation it will try to make other Messenger users to open pictures by using following sentences (translated from Finnish):
"Hi :) Are u here? :D", "Is this your pic?" ja "U were pretty drunk :D"

File names vary a lot. One of the names is photo95.JPG-www.msnimages.com.
Some of these files are hosted under .fi domains.

This is a newer variant of old Sdbot family, Backdoor.Win32.SdBot.ebp. That will make
computer controllable by attacker.

Mikko Hyppönen from F-secure thinks that trojan might have been made in Finland and that latest F-secure virus database will recognize that threat.
