Hi,

Kindly make sure you have patched your system with "Microsoft Critical patches".
You can do that from eScan Protection Center->Tools->Download latest hotfix (Microsoft Windows OS)

Once you are done with this ,do run mwavscan.com /kill parameter from command line at eScan folder and provide us the pinfect.zip file to samples@mwti.net so that we can check for new infection.
With Regards,
