Cleaned amvo.exe virus manually

Today I got one virus in my system. When I try to login to the Yahoo messenger, it is closing without logging in. I have found a virus (don't know name) and cleaned it manually. I have taken the below steps to remove this virus manually.

• First I have checked in task manager, I didn't find any suspicious processes.
• Next I opened MSConfig (Go to run, and type msconfig). I have found one process with the name amvo.exe under the startup tab. It is located in Windows\System32 folder.
• I unchecked the process, and closed the msconfig window.
• Next I open Registry Editor (go to run, and type regedit). I have searched for "amvo.exe" and found one entry. I have deleted the whole key.
• Next I have tried to set the option to "show hidden files" (Go to Tools> View in windows explorer), as virus file is hidden.
• Then I have browsed to Windows\System32 folder, and deleted amvo.exe, amvo0.dll, amvo1.dll.
• This virus put an Autorun.inf file, and .cmd file in every drive's root. I have removed all those.

Thats it. Virus was cleaned. Now, I am able to use my messenger. Don't forget to disable system restore before starting the cleaning process, and open windows in safe mode. Update: I built two files to clean this virus automatically. After downloading the AMVO Cleaner, unzip the file to get a folder. Open that folder, and double click on the file named AMVO_Delete. It should have cleaned the virus.
