Today I recieve a PM from my friends through Yahoo Messenger
Toi di lang thang lan trong bong toi buot gia, ve dau khi da mat em roi? Ve dau khi bao nhieu mo mong gio da vo tan… Ve dau toi biet di ve dau? http://chendang.net/nguyen/
This message was send automaticaly. It is repeated every 3 minutes. I’ve found -by googling- that this is caused by the infection of worm/trojan called Autolt.X. Read more at http://www.f-secure.com/v-descs/autoit_x.shtml. There you can find also how to remove this trojan.
Then maybe you ask, where does it comes from? This trojan may arrive on the system as a downloaded file via links that are spammed through Yahoo Messenger. The links have malicious Java scripts, which contain exploit code to automatically execute AutoIt.X on vulnerable machines. It exploits a vulnerability in Internet Explorer browser.
