Hello. I'm new on this forum.
I just need to warn you about a new incarnation of this little nasty here. This one prevents access to the Skype website and prevents you from running regedit.exe and msconfig.exe. It also alters your HOSTS file in c:\windows\system32\drivers\etc and prevents MSN messenger from logging you in.
Here is a transcript of the history regarding this. (I have concealed the identities of the users involved with [Xx]'s for privacy reasons):
I have broken the history down to two parts for comparison.
This is part one of the history. Notice the chatting habits of Ist[xxx]?
[5/09/2007 6:02:56 PM] Richard [X] [XxXxxxxxxx] says: Hello Ist[xxx]. You must be on another call.
[5/09/2007 6:03:01 PM] Ist[xxx] says: Hi there Richard! What's Up?
[5/09/2007 6:03:16 PM] Richard [X] [XxXxxxxxxx] says: Just saying hello.

[5/09/2007 6:04:10 PM] Richard [X] [XxXxxxxxxx] says: Well, when we get that DVD recorder I think that will change it.
[5/09/2007 6:04:19 PM] Richard [X] [XxXxxxxxxx] says: I forgot your mike's not working.

[5/09/2007 6:07:46 PM] Richard [X] [XxXxxxxxxx] says: Of course it's HDMI. We were using HDMI with the computer.

Now here is part two. Notice the difference in Ist[xxx]'s speech.
There are two links associated with this half leading to the same file "dsc027.jpg": "http://www.fakme.org/erotic-gallerys/usr5d8c/dsc027.jpg" and "http://www.myimagespace.net/erotic-gallerys/usr5d8c/dsc027.jpg". The spelling in both links in the transcript have been changed for safety reasons.

Recognize the difference guys. It may save your computers from a nasty virus.
Tips for safe chatting:
* Become familiar with the way your contacts chat with you.
* Never add a URL when you start a chat.
* If you receive a message from one of your contacts in SMS type and you know that contact doesn't chat in such a manner, treat it as a fake message. Especially when it has a URL with it.
* Never click on any links which lead to content that doesn't match the characters of your contacts. I.e. if you know your friend online is a Pentecostal Christian and suppose that there is link on his/her message, say, "http://example.pornsite.com/hotchicks.jpg" or "http://www.tarot-readings.org/example.htm"
Happy Skypeing everybody.
