DSME - should I care? What to do?

Good morning,

here and then and since a couple of days I get from Avast! the warning of a DSME detection while storing downloaded files to an already existing files. It’s an everyday updating routine. (Online protection is on).

Trying to repair is without success (though the VRDB is up-to-date).

Leaving the said infected file on the computer I’ve sent it to Avast! for an online scan and got te message “clean”.

What’s wrong? A bug in the software, a very malicious thing or what?

Thank you for any hint and help
