In a recent virus definition update the AVG company incorrectly identified one of the files in the MISTRO program as containing a virus.  AVG have now fixed this mistake in subsequent virus definaitions, but if you are having any problems with MISTRO saying it can't find ZipDLL.dll is is almost certainly for this reason.

To fix the problem in AVG Version 8 follow the following steps:

1) Right mouse click on the AVG icon in your system tray.

2) Left mouse click on  "Open AVG User Interface".

3) Click on History / Virus Vault

4) Look in the list of infections.  Choose the infection that contains the file ZipDLL.dll in the MISTRO Folder.  Click on it so that it is highlighted, then click the Restore button.

Once you have followed these steps MISTRO should begin working normally again. If you have any queries about this process, or are unsure of whatto do make sure you contact the MISTRO Help Line on 1800 451 451.
