If you get some problems when AnVir Task Manager runs

In most cases AnVir Task Manager works fine. But some features of AnVir Task Manager are system-wide and they can be incompatible with some applications or drivers. Usually it is application that affects whole system, e.g. skin system or antivirus.

Solution:
a) Add AnVir Task Manager to exclusions of that application.

b) Disable system-wide feature of AnVir Task Manager that causes incompatibles.
Disable disk temperature monitoring via Tools->Options->Tray Icons and Menu->Tray Icons->Disk Temperature

Disable system hooks that cause incompatibles.
Open Tools->Options->Windows Enhancement->System Menu and Dialogs.
Clear checkboxes:
* Show additional buttons in the titles of windows
* Add useful commands to system menu of all windows
* Add list of recent folders to "Save As" and "Open" dialogs of all programs

c) Disable traffic monitoring (Tools->Options->Advanced).
Traffic monitoring uses Windows raw sockets and may be incompatible with some network drivers or applications.
