I have a Western Digital external drive - ( wd800B015-RNN) that has 3 buttons - one of them is power. When I turn on the unit AVG2011 free starts a scan (as it should). I do some work on 1 or more files, close them and turn off the drive - another scan starts and a pop-up appears saying the device can't be turned off because it is being accessed. This was not a problem with a previous version of AVG Free.
This has happened with version 184.108.40.206 and 220.127.116.11 of wdbtnmgr.exe .
If someone thinks it might help, I would be willing to contact Western Digital.
When the drive is turned on, AVG starts removable devices scan - scanning whole drive. This can take some time, therefore if you try to turn off the drive, it is not possible due to scan still running.
You can disable removable devices scan as follows:
Tools - Advanced settings - Scans - Removable device scan - uncheck 'Enable Removeable device scan'.
Accessed files on hard drive will be still checked by Resident Shield.
For help on your issue please navigate to "c:\Program Files\AVG\AVG10\" ,rename avgchsvx.exe to avgchsvx.bac, than restart computer and try if it solve situation.

As suggested, I renamed avgchsvx.exe to avgchsvx.bac and rebooted, that seems to solve the problem of starting a scan of this external drive when I turn it off. What does avgchsvx do for the overall antivirus system?
Should I 'reactivate' it by renaming it to avgchsvx.exe?
