Hey Ujjwal ... The file you sent me was detected as Trojan.Win32.Zapchast by Kaspersky and deleted

.. So .. Better scan your system ...
Scan your system with updated virus definitions:
Panda ActiveScan
Stinger
Symantec System Check
Kaspersky
Btw ... I didnt found out more about this virus on the net ..Its just a Trojan .. You can simply delete it and live happily ever after ...
