Typical virus behavior :frowning:

Quite probably, but I don’t think you have to restore that files… Maybe you could wait for a better user to guide you.

They were kept into the Avast4\DATA\chest folder. I never tried to ‘restore’ old chested files (backing up and restoring on a new installation of avast!). Maybe it works if you copy the index file too :-\
