Yes, i'm not telling you dont need avast, but our friend didn't know which file was deleted, and maybe opening the index.xml of chest can get an idea of what was deleted. Don't get me wrong, as everything that is encrypted, you need to decrypt it if you wanna work with the file. So he can get an idea, just by opening index.xml, of what file is missing, and maybe he can restore the file from a backup, or from other machine running the same OS. and once the OS is restarted, he can just "disable" avast in safe mode. Why are you like this people? just because you have more knowledge of this, you just limit yourselves to help others if they are in your range of who deserve to be helped. Just because you are an evangelist, or a technician, it doesn't mean you can treat other people as dumb. Someone, here at the post asked him for information about the file that was deleted, and i'm just trying to help him to get some info about the file, that's all. It's not our fault if we don't know, that's why we are here, to get knowledge, and maybe in the best of the opportunities, help others that have the same issues we had.
