To clean the MAL_OTORUN virus, I tried with couple of Anti Virus, but nothing worked out. Some Antivirus quaratined the virus, but not able to fix the issue. Finaly I used combofix.
Please download ComboFix from here.

You must download it to and run it from your Desktop
Now STOP all your monitoring programs (Antivirus/Antispyware, Guards and Shields) as they could easily interfere with ComboFix.
Double click combofix.exe & follow the prompts.
When finished, it will produce a log.
Re-enable all the programs that were disabled during the running of ComboFix..

Do not mouse-click combofix’s window while it is running. That may cause it to stall.
CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.
