This is an Internet worm written using VBS script language, and it is embedded into a Web-page on the Internet.
The worm infects the system when an infected web-page is opened with Internet Explorer 4+ (and if its security settings are not set to "HIGH").
The script sends a link to itself by email to all recipients listed in Microsoft Outlook Address Book attached to the following message:
Subject: "Computer Secrets !"
Message body:
If you are using Win9x/Me, visit the following page will upgrade your pc
performance. If you are not using Win9x/Me or don't want to upgrade your
pc, only forward this page to your friends.
Maybe your friends need it.
http://xxxxxxxxx.topcities.com/xxxxxxxxxxxxx
This URL points to the infected HTML page.
This worm uses a special way of replicating, because it sends only a link to itself in the message instead of sending the whole worm.
