Avast Premier have detected a HTML:Iframe inf exploit but can't remove it

Viruses and worms

I have observed this malware attacks PDFs, MS documents and renames them randomly with a a8dc file extension. I think my windows explorer is infected too.

I have a lot of pop-ups. I have done a boot scan.

You where asked to provide the log files.

The pop up stops after two scan and boot scan by Avast. But the damage is great it leaves many .a8dc encrypted files. Just to make sure I am secured I check “Scan for potentially unwanted programs (PUPs) and Enable Hardened mode (Aggressive)”.

Thanks

Another scan information from AdwCleaner - See attached files.

For the records, it was Avast who first detect the iFrame inf exploit and remove the readme on boot scan. It stops the spread of infections on other folders.
