Visual C++ Runtime Library Error

I have just begun to experience a Microsoft Visual C++Runtime Error during
two separate operations.

When I try to open my internal “D� drive (RAID 0 - mostly video AVI files)
in thumbnail view I get the message window: Microsoft Visual C++ Runtime
Library / Runtime Error! / Program: C:\Explorer.exe / R6025 / -pure virtual
function call. When I close the window, explorer closes and I lose my desktop
icons and taskbar briefly, but they return within about 30 seconds. If I open
the “D� drive in list view, it does not occur.

The second instance occurs when I open Adobe Encore DVD. Upon initial
opening of the program there is no problem, but as soon as I open the window
to preview a DVD menu image, I get the exact same warning but with the line
Program: C:\Program Files\Adobe\Encore DVD 1.5\EncoreDVD.exe instead of the
previous “explorer� reference. Adobe Encore then closes.

At first I thought the error was related to opening images, but I have not
had a problem opening the “My Pictures� folder in thumbnail view.

I am running XP SP2 and there have been no recent hardware or software
changes. I regularly run virus scans with NIS 2008 and have also checked my
system using two other malware detection utilities – everything appears clean.

I can remedy the situation by performing a “Check Disk – auto fix errors� on
my O/S drive “C�, but after a few days, the problem returns.

I’ve tried to keep this a brief as possible while still giving pertinent
information. If more is needed, let me know. Any help would be greatly
appreciated.
