- Adds the value:
"[File name of adware]" = "[File path to adware]"
to the registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
so that the risk runs every time Windows starts.
- Attempts to connect to one of the following domains to check for updated versions of the adware:
- abetterinternet.com
- stop-popup-ads-now.com
- Attempts to perform some of the following actions:
- Display advertisements.
- Display links to related Web sites, and advertisements for related Web sites, based on the Web sites visited on the infected computer.
- Log the Web sites visited by the infected computer.
- Redirect certain URLs, including the Web browser default 404-error page, to or through the Web page used by the threat.
- Automatically update the adware and install added features or functionality. This action is performed without input from, or interaction with the user.
- Install desktop icons, installation files, and other publisher's software.
Some samples that Security Response has received of Belt.exe will not install successfully, as the CAB package it attempts to download is no longer available. In these instances, as well as those when an Internet connection is not available, the adware will add the registry key specified in step 4, and then exit cleanly.
Note: Virus definitions dated prior to November 19, 2003 may detect this as Adware.Ipinsight or Download.Trojan.
