Scan stopped at 12% again. The program doesn’t actually freeze up, it seems to be running but it won’t scan beyond this point. The file displayed was again a Word file.

This is the report generated in the log.

c:…\Outlook\Outlook.pst The process cannot access the file because another process has locked a portion of the file (33)

Outlook was open and running at the time of the scan. However, I have run an avast scan in the past with Outlook running without this problem. I tried running an avast scan yesterday with Outlook closed and it made no difference.
