AVG is stuck moving a file to Quarantine

AVG blocked the threat SIHClient.exe.  I clicked Quarantine.  It's been almost an hour and it still says "moving to Quarantine".  I ran another AVG scan which came back with no threats.  Also ran a MalwareBytes scan that came back with no threats.  I opened AVG and looked under Quarantine and it says my Quarantine is empty.  Any help is appreciated!

Hello Trish,

To be sure, does AVG threat detection popup say as it blocked "SIHClient.exe" and moved it to Quarantine?
Trish TTrish T
Here's what the exact wording in the AVG popup said:
"Threat blocked! We've blocked the threat SIHClient.exe from harming your computer. What would you like to do?" I clicked on the Quarantine tab and it said it was "Moving to Quarantine".  I've left the AVG box up on my computer and it still says "Moving to Quarantine" with a green bar moving back and forth.  (it's been doing this for over 4 hours).
I clicked on the Details tab in the AVG box and it displayed the following information:
Threat name - IDP.Generic
Process - c:\WINDOWS\System32\SIHClient.exe
Detected by - Behavior Shield
Status - Moving file to Quarantine

Also, I opened AVG and checked the Quarantine and it says it's empty.  Hope this answers your question.  If you need any more info, please let me know.  I appreciate the help!!

Thank you for the detailed explanation.
This shouldn't be happening with AVG.
May I know at what instance you received the threat alert?
Is it while running a particular application?
Do you have the latest 18.2 version of AVG Antivirus installed on your PC?
Trish TTrish T
The version of AVG is 18.2.3046.  I turned my computer on and left it, I didn't open any programs or go online etc.  When I sat down to work a few hours later, the AVG popup was on the screen.

Trish, we have fixed this issue recetly. Try to update your AVG Internet Security/ Antivirus free manually and check if it helps. 

Open AVG Antivirus -> Menu -> Update -> update it manually. 
Trish TTrish T
Hi, I did the manual update but the popup is still there and still says "Moving to Quarantine"  Do I need to restart my computer?
Balasubramanian SBalasubramanian S (Avast) 
Trish, it looks like the issue should have got fixed, but the window isn't responding.
Yes, proceed to restart your computer and inform us the status.
Trish TTrish T
I restarted the computer and worked on it all day with no problems.  I ran another AVG scan and a MalwareBytes scan.  Both came back with no threats.  Hopefully, the problem is solved!  Thanks very much for your help!

I have exactly the same issue today i.e. stick trying to quarnatine SIHClient.exe. I'm on AVG 18.4.3056 definitions 180613-0. I found a tread on the Microsoft support site saying this is part of the Windows 10 updating system. I have now gone into Task Manager and deleted the AVG process which was hanging. I uspect this is a false positive but can you confirm please and, if so, tell me how to get AVG to ignore it.
Thanks
Simon

Following on from the above post, the file is no longer in system32 but isnt in the AVG quarantine areaa either, nor is it in the recycle bin. Help please!

Hello Simon,
This isn’t an expected behavior, let's work together to fix this issue.
Could you share a screenshot of the AVG detection with "See details" page to proceed further?
You can post the screenshot here on your topic. Click on 'Answer' & then click on the 'Image' [mountain symbol] & follow the instructions.
Regards,
Alok.

Ok, I "think" this is the answer:
it was marked safe, but, Microsoft updated it and the AV companies havent updated the HASH for the new file.  As soon as AVG and other get the HASH updated this will no longer be marked as a threat.

This just started for me today.  I did some searching and it looks like Avast has been blocking this program for years.  I would like to know what the threat is???  What did AVG find that caused this threat status to change?  I told AVG to quarantine however just like Trish says above AVG is unable to handle the quarntineing of the file correctly and now if I want to restore the file out of the quarantine (in case it's a false positive) I will be unable to do so.  So, bad on Microsoft for putting code out there that isn't digitally signed (1), and (2) bad on AVG for removing a file that they're unable to allow a restore on.  Just my .02 --- Thx, Chris

I've used Alt Print Scrn to get a screen shot, but I don't know how to save that as a file, so that I can upload it here.

Experienced the same issue as Trish and Simon, did I just delete an important system file and how do I get it back???
Alok KumarAlok Kumar (Avast)
Hello All,
Thank you for providing the screenshots.
In this case, I request you to update your AVG Internet Security/AVG Free Antivirus virus definition and version (open AVG protection > menu > settings > updates), reboot your computer once.

If the issue still persists, then I request you to upload the file (SLHClient.exe) to https://www.virustotal.com/#/home/upload and give us the hash url for the further analysis.
Cheers,
Alok.

AVG Quarantine - Stuck

Hello William,

We realize the situation and may I know whether you are using the free or paid version of AVG?
If it is the paid version, do contact our chat team using this https://support.avg.com/support_tech_chat link for further assistance.
If it is the free version, do create your own post on this community as we will be able to get your account details and proceed further on this matter.
Thank you.
William WWilliam W

Notice that the file path goes to an empty directory. This is not a new program...it is quite old...and has never given me any problems before. The Windows Explorer IS SET to display hidden files.
