Thanks for the instructions DavidR. Followed them but never did get the ability (highlighted) to Restore as is shown in your example. I have no 'Infected Files' to restore. I have nothing in 'User Files'. I have three from 2006 in 'System Files'.
You have to be able to click on a file to be able to highlight/select it and enable the Restore option. You shouldn't attempt to restore the back-ups. hat surprises me is your mention of the fact that you quarantined (move to chest?) yet that file does't appear in the Infected Files section of the chest, now that is a mystery.
None of the files or the 'All Chest Files' gives me the ability (highlighted) to Restore. The only options open are the Refresh All Files (F5) and Email to ALWIL software . . . right clicking on a file gets a 'Small Icon' or 'Large Icon' option, right clicking on the word File in the tool bar gets a 'Tool Bar' or 'Status Bar' option.
The All Files entries are just a collation of the three main sections, it isn't actually a section in its own right.
I don't know why such a common problem should be so difficult to remedy. "User Friendly" is a bit of sarcasm. Nor have I found a way to communicate with Avast. They do not make it easy. If it were not for the fact that I fear losing all of my genealogy work I would flush the whole system.
It isn't that much of a common problem or it would be many topic about it in the forums.
I don't know how you have been trying to communicate or to who you have been trying to contact. Alwil are usually quite responsive on the support (at) avast dot com, however there have been times when replies are deleted by spam ISP filters (now that is common, as there are many questions about not receiving registrations keys).
As Tech said the forums are by far the easiest way to get a response.
