Overview

This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.

Aliases

• Dial/Top-A (Sophos)

Characteristics

After execution, the trojan starts dialing without displaying any dialog or warning messages. It does not make any changes to the registry or system files.
