Error: file protected by password (42056)

[nelyok7]

Good evening all, I was just doing several scans (a complete one, a fast one, etc.) and when I scanned my hard drive I got an error in some files I could recognise and they were some of the .dat of a folder with a version of Adobe Photoshop CS6 Portable (downloaded from the internet, but secure) and a file from an Avast internal folder. It is a bit strange, as the complete scan didn't find a single issue and the Windows Explorer of my C:\ drive found the error mentioned before. The folder was located in \Desktop, and as I protected the Desktop folder with the recently added Ransomware Shield that could be a reason for that (Avast doesn't trust itself!?), but I don't think so. I located easily the folder, and used 7zip to open a .cdd file where the "protected files" where. 7zip opened it but still marked a wrong password, and I scanned the files on their own and they where clean. What did happen, which program created the password for these 3 files? I have no idea... And the avast internal detections (even more strange)... Are these:

C:\ProgramData\AVAST Software\Avast\IDS\outbox\tmp_21f051bd-3dc4-47cf-99ed-b56e7140ca0d.zip|>nodes.xml
C:\ProgramData\AVAST Software\Avast\IDS\outbox\tmp_21f051bd-3dc4-47cf-99ed-b56e7140ca0d.zip|>ExternalData.xml

Can anyone identify these files?

My laptop is working fine (no virus symptoms or rootkits, no detections in scans) but having protected files (and not knowing the password!) is just really annoying!

Thanks for all the help in advance!

I just went to VirusTotal and found some really weird things (Parent folders as virus)... Can anyone experimented or from the Avast Team help me with these suspicious files? They are secure (marked as signed with a secure protocol) and created by Avast! Please help, I don't know what to do.

PS: The new version of VirusTotal and the Relation section is useful but I'm now really worried!

Thanks for the really fast reply, and the Avast guide made me feel a bit relieved, but I want to know, is there any way that these files can harm my system while they are protected and Avast doesn't handle them? I'm still a bit worried. I would be grateful for somebody that could confirm te files' identitity...

Many security programs protect there own files with encryption/passwords. Adobe is another program that does so

Avast realtime protection will scan these files when whatever use them access those files
Avast realtime protection monitor EVRYTHING that goes on in your computer when on

Ok, I get it, and thanks for the reply. Avast may be a clear case, but the Adobe Photoshop CS6 is a bit of a"pirate copy" as it was a portable folder downloaded from a website My last doubt is... Why Avast didn't mark this password protection before (as I downloaded the CS6 version 2 months ago)? I did the same scans... (same goes with Avast, installed in January 2017)
