IDP.Generic Threat Detected by AVG Antivirus: File in C:ProgramData & Proxy Connection Reset

Hello,
AVG Antivirus detects certain file as IDP.Generic threat. This file is in C: \ ProgramData \ and cannot be deleted.
Trying to clean with adwcleaner does not help. I also noticed that from then on, when AVG detected this threat, it keeps restarting the proxy connection setting. I attach logs from the FRST application to the topic.
Best regards.

I removed AVG PC TuneUp and ran the Fix with FixList.txt option
As for the file, it is located in: C: \ ProgramData \ 4D9BFDB2 \ 4D9BFD32.dll

From what you can see in the log, it has already been removed, there is not even the C: \ PROGRA ~ 3 \ 4D9BFDB2 \ directory.

To be sure, you can add to Fixlist.txt:
C: \ Program ~ 3 \ 4D9BFDB2 \

I advise you to be careful in the future and not to run infected false invoices that you receive by email.

It was one of the employees of the company computer who infected the computer in such a way because she downloaded the file with the invoice. Thank you for your help.
