2. ADW_CNSMIN.G

This adware arrives on a system via the Internet, or bundled with other applications. It does not have a valid End-User License Agreement (EULA).

3. WORM_NYXEM.E

This worm propagates by attaching copies of itself to email messages that it sends to target addresses, using its own SMTP engine. Through this SMTP engine, it is able to easily send the email message without using other mailing applications, such as Microsoft Outlook.

4. TROJ_GENERIC.Z

Malware Type: Trojan
This is the Trend Micro generic detection for low-threat Trojans.

5. WORM_ANIG.A

Malware Type: Worm
This memory-resident worm propagates by dropping copies of itself in shared network drives. It steals login information and saves the obtained data in a file, which can be retrieved by a remote user.
