Quote - as fo Stans complaint, it is a legitimate concern.

Again, then why not find out?

Heuristics are for guessing if it's a brand-new malware, which hasn't been reported to anyone yet. They are a yellow flag, not a red flag.

More effort is required from the safety-consious user.

 

Simplest thing he could do is set the files aside, for a while, and scan with the next upgrade/update (whenever Avast says they've fixed their issue).

More proactively, scan with multiple online scanners.

Multiple files? See what the A/V thinks they are. If each one is a different brand-new malware, then you know you've got an infinitesimal chance that Daz was the first one infected with each one.

Or report suspicions to a security site, and see what they advise.
