I have just been sent a trojan horse through MSN ...
It starts like this:
HAHA this is you >> with a link!! and it looks like it's a contact on your msn that sent it.... It isn't... don't be fooled.
Please don't open, it's a virus.
It has just took me nearly 1hr 30mins stuck in safe mode doing a full system scan.

It's gone now.
But I just wanted to warn you all!!
