Technical DetailsVBS/Vierika is an Internet worm, programmed in Visual Basic Script. The worm code was directly implemented in the HTML document Vindex2.html and is available on a GeoCities website, to start when the site is launched, automatically.
The worm creates a file named Vierika.jpg.vbs on drive C:\, which contains no worm code or VB script, but just the word "free".
Then, the worm starts Microsoft Outlook and sends itself to all email addresses in the Address Book. The email has an attachment.

The worm changes the start site of Internet Explorer into
http://www.geocities.com/msxxl/Vierika.html.

When the email attachment is opened, the Internet Explorer start site is the above mentioned one. So, when Internet Explorer is launched, the site is opened and the worm is activated.
