Why give up it isn't much hassle, you didn't say why it didn't work when you tried to copy the file to the suspect folder. I suspect you mean avast alerted.
1. Did you first create the exclusion C:\Suspect\* in the standard shield ?
2. Did you pause the standard shield whilst trying to copy the file ?
I can't say how to password protect your zip as I don''t know what you are using, but 7zip is probably the easiest one I have seen for adding a password to a 7z file.
Or you can also add the file to the User Files (File, Add) section of the avast chest (if it isn't already there) where it can do no harm and send it from there (select the file, right click, email to Alwil Software). No need to zip and PW protect when the sample is sent from chest. A copy of the file/s will remain in the original location, so any further action you take can remove that.
Edit: where did you download this from ?
I just downloaded it from Softpedia
http://www.softpedia.com/progDownload/TitleBarClock-Download-16492.html, version 1.4 and I didn't get an alert on download.
Edit 2: The alert happens on installation on the file you mentioned, but it didb't happen when I extracted the installation file and scanned that.
