Hey there.

I'm running Vista 32bit, I have avast and a spybot. I turned Defender off because it seemed to be causing the system to crash on start up. I previously had avira running but it would only manage a complete scan in safe mode, in normal it would freeze and the computer would have to be manually restarted. It always stopped at "winsxs\...\ehiExtens.dll" so i uninstalled avira, hoping it might be a conflict or something. Now I have Avast which will do a full scan, but stalls briefly at the same point and then in the scan report the same file ("winsxs\...\ehiExtens.dll") will come up with the comment "Unable to scan: The system cannot read from the specified device".

When I googled 'ehiExtens.dll' one of the few sites that came up was microsoft's most recent update the 'Cumulative Update for Media Center for Windows Vista (KB960544)', which is also failing to install in this computer. Surely thats not a coincidence?

Anyone got any ideas about this?

Thanks, Leeford.

Having been through part of the winsxs folder, the file below was the only one in the section that keeps causing the freeze to cause another freeze when i used avast file scanner.

Does anyone know if it's wise to delete, or otherwise, this folder and its content? Even if it doesn't affect the update problem, it might allow Malwarebytes and others to do a scan without freezing, right?
Thanks Leeford.

Yep, that's reasonable. Try renaming the file (but remember the old name) and see if that helps.
Otherwise, delete it to the Recycle Bin (so you can restore it if it causes problems).
