Avast Antivirus have problem during the application launch

Hello friends,

When I try to launch the Avast I ended up with an error message. The error message says that some dll file is not there. I tried to re-install the application, but again I ended up with the same error message. And also I tried to repair the application by going to control panel, nothing worked. Please help me to sort the error. Thanks.

This application has failed to start because MFC71.DFF was not found. Re-installing the application may fix this problem.

Mfc71.dll  errors are caused when the mfc71.dll file is deleted/moved possibly by a poor installation or un-installation. Even if though not asked you must restart your computer after the uninstall (not repair) and before the reinstall.This will help to ensure any loaded files are cleared from memory. This file is related to the Microsoft Visual Studio .NET 2003 (You may not be using it but it might remain installed in system). You can download Visual Studio .NET 2003 from Microsoft website as well.

Do not download the mfc71.dll individually from any "DLL download site." The IE  is another source of the mfc71.dll file. So you may also try to install latest IE version from a reliable source.
