Don’t disable the protection, exclude the file. In my post above you will see you can add the file location to the exclusions lists.

What is a surprise to me is that the file is in a Temp location (the same as the other topic) and not the ashampoo program folder. So it must be generated by ashampoo, a crazy situation using the temp folder for something to stealth ashampoo I believe.

You should also send a sample to avast for analysis.
Also see (Mini Sticky) False Positives, how to report it to avast! and what to do to exclude them until the problem is corrected.
