This has been happening a lot lately. I have followed the tutorial in https://forum.avast.com/index.php?topic=53253.0 and are attaching the text files requested. If the Norwegian is bothering you, I can translate.
Is there anything I can do? It has been going on for some time, ever since I tried to change the ROM on my phone, and got recommended to download a program called ODIN a samsung rom flashing tool. This file was immediately blocked once I downloaded it.
Please download ZOEK by Smeenk and save it to your desktop (preferred version is the *.exe one)
Temporary disable your AntiVirus and AntiSpyware protection - instructions here.
[*]Make sure that Scan All Users option is checked.
[*]Push Run Script and wait patiently. The scan may take a couple of minutes.
[*]When the scan completes, a zoek-results logfile should open in notepad.
[*]If a reboot is needed, it will be opened after it. You may also find it at your main drive (usually C:\ drive)
[]Remove disinfection tools
[]Purge system restore
[*]Reset system settings
[*]Push Run and wait until the tool completes his work. All tools we used should be gone. Tool will create an report for you (C:[B]DelFix.txt)
The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.
