Summary:

Trojan. A program that appears to do one thing but actually does another (a.k.a. Trojan Horse).
WormAutorun. A worm spreads via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Worm's file once a user opens a drive's folder in Windows Explorer.
IRCBot. A bot communicates with command and control servers via IRC channel.
MSNWorm. A worm spreads its copies through the MSN Messanger.
DNSBlocker. A program blocks designated DNS servers for making it difficult for users to locate specific domains or web sites on the Internet.
UDPFlooder. This program can make a UDP flood. A UDP flood attack is a denial-of-service attack using the User Datagram Protocol (UDP). It can be initiated by sending a large number of UDP packets to random ports on a remote host.
SYNFlooder. This program can make a SYN flood. It is a form of denial-of-service attack in which an attacker sends a succession of SYN requests to a target's system in an attempt to consume enough server resources to make the system unresponsive to legitimate traffic.
USBInfector. A program registers a device notification with the help of RegisterDeviceNotification so it is notified when a USB device is plugged and then the worm copies itself to the USB device plugged into the affected computer.

Process activity

The Worm creates the following process(es):

Propagation

A worm spreads via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Worm's file once a user opens a drive's folder in Windows Explorer.

2. Update the definition files.
3. Run a full scan of your computer.

Manual removal*

1. Scan a system with an anti-rootkit tool.
   
2. Terminate malicious process(es) (How to End a Process With the Task Manager):
   

   9410c63b7611ce4116719c62b677567d.exe:464
   9410c63b7611ce4116719c62b677567d.exe:2008
   Eukmkq.exe:1076
   Eukmkq.exe:988

4. Delete or disinfect the following files created/modified by the Worm:
   

   %Documents and Settings%\%current user%\Application Data\Eukmkq.exe (673 bytes)

5. Delete the following value(s) in the autorun key (How to Work with System Registry):
   

   [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   "Eukmkq" = "%Documents and Settings%\%current user%\Application Data\Eukmkq.exe"

6. Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
   
7. Reboot the computer.
   

*Manual removal may cause unexpected system behaviour and should be performed at your own risk.
