Routine "healing" procedure deletes good exe files

[dennis_b]

During what seems to be routine scans about once a week my Avast (version 6.0.1367) dicovers "infected" files and in the process of "healing" them it deletes a good file (pkzipw.exe) that I use regularly.

Can anyone tell me how to stop that?

Check the file with www.virustotal.com
Add an exclusion to avast on-demand scanning and also in the on-access (resident) scanner.

What do you mean by healing them ?
So when is this file detected, e.g. what scan and what malware name does it give it ?

Avast doesn't delete anything autonomously, the default action on detection is move to chest unless the user selects the action to delete.
