and i am happy to say that i did not get another notification since the last restart! Nice! :smiley:
Does this mean my PC is clean, or should i do some more testing?

Report if notification returns.

Rename FRST64 to uninstall and run it. It should uninstall FRST.

Will do. Thank you so much!
Can you explain in layman’s terms what exactly happened?
It seems like it was a Trojan that kept trying to download a payload via a blocked website, am i correct?
Any way i can find out how it got on my PC? And how is it possible that Avast did not notice it in the first place? And why did not even Malwarbytes detect it?
Sorry for the many questions, i am just very interested and confused. :slight_smile:

Trojan that was run on PC created BITS download job and deleted itself. Payload was meant to be downloaded using Windows but it was blocked by Avast.
