I can't check the movies with virustotal because they are too large (though I don't believe they are that large - the computer doesn't have enough space for them all).
I checked one of the codec packs that "came" with the movies though and VirusTotal says this...
Should I now delete the file from the suspect folder?
Whilst they may not be 320GB, they could easily be more than 25MB.
Strange that avast didn't show a detection on that VT scan.
I'm always wary of codecs as they are a huge target, so you should be confident of the source you are getting them from. I usually use the K-Lite Codec Pack and its updates. Yes you can remove the 'copy
' you placed in the suspect folder.
It can't be in the chest and be in use by another program/person. Since you don't see an extract option, you aren't inside the avast chest ?
As your edited first post now states, "Avast can't delete or quarantine this dropper." So it isn't in the chest but in its original location, in which case copy it to the suspect folder that you created and excluded (given in my previous post). Then you should be able to upload it to VT for scanning.
That's one of the problems. Avast doesn't put it in quarantine and when I try to copy it it gives me the message that another program or person is using it.
Even if I try scanning it from its original location VirusTotal won't work, just says computing hash and freezes.
Try opening the avast chest, from the GUI, Maintenance, Virus Chest, right click in the right side of the window and select Add, from the new explorer like window, navigate to the MediaIconsOverlays.dll, select it and click Open (it doesn't actually open it), but copies it to the avast chest.
From here you should be able to 'Extract' it to the suspect folder and upload to VT (fingers crossed).
