I don't know what this is but it's happened to me twice.
Last night a friend tried to message me and a weird download in .zip appeared and I declined. Supposedly the friend had said inside was a picture of a beautiful sunset. Well...thought it was weird, and my friend didn't know what I was talking about.

Today a DIFFERENT friend messaged me saying this and with a weird zip also.
haha this guy up my street just slammed his 0k car into a telephone pole! I got a pic of it with my cellphone

Then he said hi.

Then here's the zip.

It always seems to happen on the first message. Also they have had these problems too. Any ideas?

it sounds like your contacts have msn viruses

get them to change their passwords and then the messages should stop being sent

set auto decline all invites till it stops
