Avast Free: Installation nicht möglich

[REDACTED]

Hallo,
habe mir ein Trekstor SURFTAB® TWIN 11.6 Convertible mit 2 GB und Win10/32 für unterwegs zugelegt.

Office 365 de- und Libreoffice installiert
Firefox und Thunderbird installiert

Als AV war McAfee vorinstalliert, mit dem McAfee Removal Tool runtergeschmissen.

Dann versucht, Avast Free AV zu installieren. Der Installer (über PC-Welt und bild.de) wird geladen, die Installation bricht aber schnell ab.
Er meldet mir, dass die UAT.vpx eine invalide Signatur hat. Komplette Meldung am Ende dieses Posts.

Da ich nicht komplett ungeschützt durch das Web segeln wollte, habe ich mal die Avira Free Av installiert, das ging problemlos. Avast wäre mir allerdings lieber, da ich das auch auf anderen Rechenknechten einsetze. Oder sollte etwa die Anzahl der Installationen für die Free Av begrenzt sein? Habe z.Z. 1 altes Notebook mit XP, einen Pentium mit Vista und 2 Rechenknechte mit Win10: Pentium von Win7 auf 10/32  und einen i5 von Win8 auf 10/64 geupped).

Würde mich freuen, wenn ich von dem Convertible das ungeliebte Avira wieder entfernen und Avast dafür installieren könnte und bin für zielführende Tipps dankbar.

Hier der komplette Ladevorgang bis zum Abbruch (Username durch xxxxx ersetzt):

Oder sollte etwa die Anzahl der Installationen für die Free Av begrenzt sein?

Nein, keineswegs. Mach folgendes...

Zuerst sicherstellen, daß keine Reste früherer AVs übrig sind..!!
-> https://www.avast.com/de-de/faq.php?article=AVKB11#artTitle

Danach:
1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
2. Folge exakt der Anleitung: https://forum.avast.com/index.php?msg=552606
3. Avast mit dem Installationsprogramm aus Punkt 1 neu installieren.
4. System neu starten.

Danke!

Mit der Offline-Installation hat es geklappt.

Bitteschön.

Hello,

I've tried this procedure 5 times or more (get avastclear.exe and install avast_free_antivirus_setup_offline.exe, disconnect from the net, uninstall, avastclear in Windows safe mode, restart, install offline version, restart).

Never worked for me. There something still on the computer that the procedure can't clear.

My Avast still have the message "File uat.vpx has invalid signature when installing or updating."

I'm unable to update the software nor the signature database.

The installed version of Avast find no virus or malware. Neither Malwarebytes.

I'm actually running on Windows Defender.

What to do now?
