Has something wrong lodged in my laptop?

I once again started a (virus) - search and then I was u.a. Something displayed…

"Heur / APC"

https://www.avira.com/...hreat/HEUR

Is that harmless or not? And what does the APC mean?

Found Avira based on his heuristic.
Could be dangerous, but it does not necessarily (false alarm).

And what does this APC mean?

Basically means that Avira has found something potentially suspicious. But does not have to.

Avira Protection Cloud

But that was under "virus found".

Aha.

Because Avira classifies it as Potentially Dangerous, do a scan with Malwarebytes

Ok, I will do it.

Run Adw Cleaner over there and / or upload it to Virustotal.com to see if it's a false alarm or not.

At 1.Scan everything was under suspicion of Chip.de. Just put it in the quarantine. When 2.Scan nothing more.

And so is everything ok?

Should fit so far
