Can't find the virus in the virus chest. Logs are gone?

Viruses and worms

Hello,

So, 5 minutes ago I received an alert from Avast that a Virus was noticed. It was something like masterbuilder IDP generic, I don’t remember well.
The fact is that I moved it into the virus chest as requested by Avast, but I can’t find it there! The last “virus” that I can see is from 15 days ago and there is no trace of this “virus”. Also in the history no trace of it, neither in the notifications.

That’s strange as I didn’t install anything new aside from games from the Xbox App but in a different HD, even if in this one there’s a folder named “msdownld.tmp”, so I guess it could be something related? Even because Avast got triggered immediatly after I closed a game on Xbox App.

So my question is: Do you think could be related to the game? Also, How can I see what was the virus? There’s a log I can enter to see the details of the window I saw?

Where should I look exaclty? Because in the report folder I can’t see it, all the last entries on the txt files are from 2 days ago, maybe I’m looking in the bad place?

I just would like to see which files Avast was indicating in that window that has been opened. Could it be a bad virus deleting its traces? That’s seems absurd.

Thank you!

The fact is that I moved it into the trash bin as requested by Avast
"trash bin" do you mean avast chest (quarantine) ?

Yes. A window opened and I clicked “move it the chest”. But I can’t see it there or anywhere. Does it make sense? I would like to undestand what that file was, how can I do it? Thanks

Without knowing more details it is impossible to guess.

I know when the dark brown stuff is hitting the fan, it is hard to think before acting. Taking a screenshot really helps with any investigation. Short of that the information may be in the report files (but you don’t say where you looked), but which one.

I suspect that it may be the File System Shield or possibly the Web Shield (it also depends on your avast settings). For the location for these files, see attached image, click to expand.

I know, I should have taken a screenshot, but that’s the first time something like this happen and that’s really strange. I can’t find anything relating to yesterday on all the reports… I can’t understand.

I ran rkill and did a Malwarebytes full scan + an Avast one and nothing was found.

Also, the support is going to help me through remote control through logmein now.

Any other suggestions? Thanks

You’re welcome.
If this is the Avast support you are talking about, then you are in better hands than mine, an avast user just like yourself.
