I just updated Avast from v17.8.2318 --> v17.9.2322.
On Windows XP SP3, the new installation created a serious problem in copying JPG files. When copying a *.JPG file, it appeared to be copied, but the file could not be opened (Error: Can't read file header! Unknown file format!). The most serious problem is that neither the original file or the copied file can then be deleted because explorer.exe is still processing the copy. This then causes an additional problem when trying to shut down because WinXP has problems terminating explorer.exe. After rebooting, the original and copied files are both readable, but neither can be copied. This does not occur on all JPG files, but only about 10% of them. I don't know if other file types are effected.
This problem occurred on both my WinXP SP3 PCs. I UNINSTALLED Avast 17.9.2322 and the problem completely disappeared!!
Is this fixable? Are there settings in Avast that could be adjusted to prevent this problem? Or am I stuck with v17.8.2318?
The problem does not seem to be present on Win7x64.
