What is the solution finally?
Hi,
I'm still having the same problem. I updated AVG today (17.6.3029), but when I try to restore the file from quarantine it does not give any message but does not restore the file. When looking at the "C:\ProgramData\Avg\Antivirus\chest" there is only the index.xml file which contains info about my file, but the file itself is not in the "chest" folder. Is there any other option to restore my file than just reinstalling? That would be quite annoying…

I encountered the same [roblem described above. But there was no small icon next to the close button. please offer help. The quarantined files have affected my other importnt application.
Hello S B,
We do understand your concern. Presently you can find a small icon next to the close button to restore the files from the Quarantine. Please click on it and check if it helps.
Thank you.

Hi!
I can confirm, that I\m unable to restore file from Quarantine. More informations are here: https://file.io/xP5hYu
May I just say that this isn't a good design? There should be a gear or something to indicate there is more to the menu. I just upgraded to the latest version and I would have never found this option myself without looking it up.
Did you find the button ?? 
where is it ?? I Need it urgently
I ran into the same problem this morning but was fortunate to have been able to restore almost all of my quarantined files from backups after I found the folder that AVG 2017 stores the quarantine files in, along with an index file showing the full paths and filenames.
This will at least allow you to see exactly which files were quarantined and allow you to restore them if you have backups of your important data, as everyone should…
My full post can be found on the topic by Johnson Cheam, accessible by the link in the post above by Alan Birch. Below is an extract of the part which may help some of you.
The quarantined files are now stored in the following directory:
C:\ProgramData\Avg\Antivirus\chest
Note that ProgramData is a hidden, system folder so you will need to type it in the Windows Explorer path bar if you do not have 'show hidden files' selected in Windows 'folder and search options'.
The index.xml file will allow you to see the full paths and filenames of all the quarantined files, which are stored in the same folder. Unfortunately you will be unable to restore the files manually as they have been encrypted by AVG, rendering them unreadable. As such you will need to wait for the AVG developers to fix and update the Quarantine section before you can recover any files, unless you have a backup system which you can recover them from.
I am having the same problem. THE RESTORE BUTTON DOESN'T DO ANYTHING. This is really starting to frustrate me because the file removed is interefering with the reinstallation of the program! A google search has shown that this is a common problem that AVG HAS NOT figured out. They always give the same generic answer and then go ghost when it doesn't work.
Of course: restore back ups for quarantined files that pose NO threat!
Every company works on the philosophy that it is your problem not theirs! What were you thinking.
My advice is prior to restoring anything, simply uninstall AVG - problem solved.
Basically same problem, I check box and before I can even go to click restore box automatically UNCHECKS.
Found a real easy fix, uninstall AVG and use another Virus Protection; guess one can't expect much from a Free version but it sounds like paid version is even a problem. Or maybe I'll reinstall Zen it worked great and stay away from these screw up UPDATES.
After repair now i can select the file and and click restore but my file doesn't restored
Deyan,
Thank you for your patience.
This bug is forwarded to senior team for analysis. You can expect the fix through update as soon as possible.
I appreciate your patience and understanding in this matter.
Thank you.
So I am currently having the same issue. I didn't say anything a month or two ago since I assumed it would be fixed by now. Though I do see someone above saying it's fixed in the latest version. Am I below that version still? If so, is there a way to force update?
I have some harmless batch scripts that have been locked up by AVG for around 3 months now (randomly, after not caring for months about them).

Hi all,
so any solution for this issue?! I need restore some apps urgently…
I just bought AVG Ultimate and it has quarantined some font install programs that I know are not viruses and it will not let me get the files back out of quarantine!
WTF AVG??
I will be requesting a refund and moving to a different antivirus. This problem has been brought to the Attention of AVG for almost 3 months and it is still happening even in the PAID versions.
I have made a video of the problem and will post it at CloudAdvice and Spiceworks so that other system admins don't make the same mistake and buy AVG.
