Firefox 26 Install Being Blocked

[ritchie58]

While attempting to install the newest 26.0 version of Firefox I got this quarantine response (see image). I tried to restore the file and run the installer again but I just get the same quarantine response. I even tried to completely kill Immunet and I stll can't get version 26 to install. It seems that install 7zip file can not be opened at all now.

I did finally get Firefox 26 installed. What I had to do was enter the Win 7\Users\Ritchie\AppData\Local\Temp folder and delete the 7zip file and then I hid Immunet's tray icon and used the cmd command to stop Immunet. Then I ran the installer again and it installed ok after that.

Hi Ritchie,

 

Can you send in the Sha256 of the file? (If you can't get it, you can just send us an SDT and I'll track it down).

 

EDIT: Actually, if you could send in the SDT that would be best.

 

Regarding the issue, is this what happened?

 

-Downloaded newest firefox version.

-Attempted to install it, got quarantined.

-Restored the file.

-Ran the file once more (same file or was it another download?), got quarantined

-Stopped Immunet, attempted to run the file again

-Got a 'No access' message (as per your screenshot #2)

 

-Jose

No problem Jose, I'll send in the SDT report as soon as I'm done typing this thread. Since it was a temp file that automatically got deleted there's no way to get the SHA256 hash for the file. I used the same installer at each attempt that I downloaded from CNET and kept getting a quarantine response with the same detection name even after using the Restore option. This is because the 7zip file name would change after each install/restore attempt I think. This is when I got the 7zip error message after trying to run the installer again, even after turning off all settings but not killing Immunet. I even tried to completely kill Immunet and run the installer with the same 7zip error results. That's why I deleted the original zip file knowing it would just be recreated again and completely killed Immunet "before" trying to run the installer again but that did work thankfully. I didn't even think of getting the hash when the file was still present. Wish I would have thought of that. Sorry about that.

 

SDT report sent. :-)

As far as updating software I normally will temporarily turn off "Monitor Program Install" and "Blocking Mode" in Settings when, for instance, Microsoft pushes any updates my way knowing these are legit files and to speed up the install process a bit. I've never had to do this with Firefox in the past as no FP's have occurred while updating to a new version. However, I think I'll start using this same procedure in the future when the next FF update comes just to possibly avoid any future scenario like the one that transpired.
