i started avast main program and since tonight, i don’t have anymore skins… and a new interface ??? what happened ?
:o

ooops !! :-[ sorry, i noticed that activate the skins was not ticked… shame on me…

but i don’t know what is the explorer skin ?

Most probably the Windows Explorer context menu…
If you right click a file into Windows Explorer and scan with avast you will see it… (ashQuick.exe)
