Explorer.exe infected

Hi,

My Avast detects a risk on explorer.exe and a popup is constantly displayed. It seems explorer is infected by a rootkit or similar

I have executed avast detection on boot, and other softwares like Combofix or tdskiller but popup still is here.

So, what can i do??

AVAST is version 2015.10.0.2208 with all virus updates. WINDOWS is w7 Sp1 Professional 64b.

Thanks

Roberto.

Attach your basic diagnostic logs. (MBAM, FRST and aswMBR)

There will be leftover files … you need to attach the requested logs

Important are the two diagnostic logs from FRST

Malwarebytes logs only?
