Instant Messenger Viruses
It seems there is an instant messenger virus at large at the moment. The virus sends messages similar to these (the URLs are deliberately obfuscated):
"Hot or Not? hxxp://mymsngallery.my.funpic de/viewimage.php?youremail@someplace.com"
or
"this really looks like you hxxp://mymsngallery.my.funpic de/viewimage.php?youremail@someplace.com"
Opening the page actually calls up an executable file that infects your computer with malware.
