Today one of the valuable readers of Technize mailed me about his problem. He has Bitdefender Internet Security installed and he was using some folder protection utility to password protect some of his important files. But Bitdefender Internet Security suspected all those password protect files as rootkit hidden items and then renamed them to filename.extension.bd.ren.bd.ren. I searched the Bitdefender site and found out that Bitdefender has got an option to rename the infected or suspicious file. Here’s a list of what all options Bitdefender offers:
Action
None (log objects)
No action will be taken on infected files. These files
will appear in the report file.
Prompt user for action
When an infected file is detected, a window will appear
prompting the user to select the action on that file.
Disinfect files Disinfects the infected file.
Depending on the importance of that file, you can
select to disinfect it, isolate it in the quarantine zone
or delete it.
Delete files
Deletes the infected files immediately, without any
warning.
Move files to Quarantine
Moves the infected files into the quarantine.
Rename files
Changes the extension of the infected files. The new
extension of the infected files will be .vir. By renaming the infected files, the possibility of executing
and thus of spreading the infection is removed. At the
same time they can be saved for further examination
and analysis.
Rename files has a similar effect on the hidden files (rootkits). The new extension
of the detected files will be .bd.ren. By renaming the detected files, the possibility
of executing and thus of spreading the potential infection is removed. At the same
time they can be saved for further examination and analysis.
How to restore these .bd.ren files?
Restoring these renamed files to their original position is very simple. You only have to remove .bd.ren from the file extension and it will start working again. suppose if the file was example.jpg.bd.ren, just remove .bd.ren from the end of the filename so that it becomes example.jpg. Now the file will open in it’s default application. If you have any other questions or suggestions regarding this article, please leave a comment.
Note: You can download the Bitdefender v10 User guide from here.
Note: If you want to rename multiple files at once, please see the following guide:

Hey i have tried to renaming the bd.ren.file but problem now is it still is REN FILE and i have to use open with> Word everytime i have to open this File so is any way to change the TYpe of the FILE permanently
Hello
I have had bit defender rename about 1000 of my files, and i really dont want to go through each one and rename, is their anyway i can rename all back to j.pg files easily ?
many thanks John
i tried renaming the files from .bd.ren to the original format..bt it didnt work..plz tell me how to restore them..am desperate!!!!
i have tried to rename the file but did not work…………..how to change the file format…………..there r so many files…….
Rashid, you need to go to Control Panel –> Folder Options –> View. Uncheck “Hide extensions for known files”. This will give you the extension of every file along with it’s name while renaming. Please change the extension to the format it was before.
Thx Sanix
But i have not been able to do it yet…i did what u said…renamed file…..but what do u mean by changing extension ? when i rename or open it doesnt and says it may be damaged…….pls help
Rashid, changing the extension means chaning the filename after “.”. For example if there is a file called technize.jpg. If I want to change its extension to png, I will rename it to technize.png. And the file may be corrupt because Bitdefender has scanned it and if it has cleaned it, it may have got corrupted. Can you tell me what files you want to rename.. the names of the files along with their extensions…
the files are jp,bmp,rar,wmv etc means mostly pics and clips…..
do i need to uninstall bitdefender in order to retore these thing….when i rename file,the icon does get restore but file doesnt open….as a matter of fact i had stored all these files in MY PRIVATE FOLDER which is a password protected software….that got removed by the bitdefender…when i click on MY PRIVATE FOLDER icon…it doesnt open rather starts creating new folder and asks ne to remove previous
Dear Sanix………..waiting for ur reply
Dear Sanix…..the files r still not opening…. anxiously waitinf for ur help
Dear Rashid, I sent you a mail regarding your solution. I think you didn’t receive it. Please send me some sample files that have been corrupted so that I may analyze them. Mail me at:
sanix[@]technize[.]com

dear sanix….waiting for ur reply
Hello Sanix! Please help me to restore my files to normal. I tried renaming them like you said in the earlier posts and it worked fine, ut I have so many files having this extention from BitDefender “.bd.ren” and some of them even double just like this “bd.ren.bd.ren”. How can I restore all my files at the same time because it will take me forever to change this file extention in each one ( I have over a few thousand files amadged by BitDefender). I have already deleted BitDefender from my computer. Second thing about BitDefender is that it deletes files not even asking me if BitDefender thinks that it’s a virus or spyware and it deleted many files that I needed and they weren’t viruses or spyware. So I decided to remove it from my PC but it didn’t help to solve the “bd.ren” extention I thought that if I remove BitDefender all files and folders will be normal again, but nothing hapened.
Please help me to restore all my files to normal!! Is there a program software to do that or any other way…
Thank You very much in Advance,
Lion
Dear Sanix
I actually tried to scan my files with BitDefender again hoping that it will bring my files to normal, but it didn’t. I had my files hidden by “Folder Lock” now I don’t have folder lock as well I use a freeware software which works great, but my files are still with this “bd.ren” extention…
i have over 500 files named as bd.ren…wat to do im desprate..do u have any other solution…plz reply
Dear Sanix u seem to be very busy these days otherwise u dont take that long to reply
anyways take care and reply when u r free
waiting for some solution of the problem from ur side
thx
Dear Sanix,,,,any solution found?
Rashid I’m so sorry about late reply. Actually I was stuck in my exams. I have tried to analyze your files but the problem with your files is that their headers seem to be corrupted as they are not giving any information about the type of file.. have you found any solution? If yes then please share with us. Thanks for being patient and consistently visiting technize.com.

waiting for reply.
I have hundreds of files which are affected because of this extension change. And all of them are images(.jpg format). How to restore the extension of all files at one go? I cannot sit and change extension of each and every file again and again. Reply awaited.
Thanks!!!
Hi all,
Sanix’s solution has worked for me! Just need to rename the files (whatever they are… jpg, wmv, mpg, etc.) deleting/removing .bd.ren and keeping the original name and extension.
If you have lots of files use the “Renamer” – see above “Rename Multiple Files Atonce”.
Thanks a lot Sanix.
JR
Hi lion,
which freeware are you using in place of “Folder Lock”?
Thanks

World No. 1 bad antiviurs……………. plz dont’s install………….this antivirus
Thumbs up for you Sanix. However, I have one more question.
I have successfully changed the file types back to normal, but the folders which the files are contained still has .ren in its name. Does this affect the files when I use them?
Details:
The files that I’m talking about are for installing a software.
Rephrased:
When I install the software, would it have an error whilst the sub-folders still has “.ren” in it?
Epilougue:
I will try to test it though… Goodluck on your exams.
Philip thanks alot for your feedback. Actually it depends upon the software. If the softwares looks for the same folders, then you’ll have to rename the folders also using the same tool I’ve described. Otherwise if the software is working without renaming, then you can feel relax and enjoy yourself
hi i am karthik i got a problem my 1000 of my pic change extension to .bn.ren even after i rename it it original i can’t open continuously in any pic viewer,.
help me to solve this problem any software is available ..mail me to my id plz those files r imp to me
i have the same problem, i protected some photos with a password program and bitdefender renamed the extensions to .bd.ren. I donwloaded that program from torrents, now my question is “would it be possible for anyone to download those pics from my computer if i downloaded that program from them? with some hacking software hidden thru the password programs file or smth like that”
hello.
got the same problem. could you please email me personally how to recover my files? I try using Renamer, and the files turns out to be normal again, but I stil can’t access it contents.
Thanks in advance.
P/S: I’m really dissappointed with BitDefender
thanks it worked for me using renamer
@Sanix technize.com
Thanks buddy I manages to rename multiple softwares by the help of your suggested application ‘Metamorphose2′.
But I want to mansion one thing here that is the software is not so easy to use and also it doesn’t rename folder within folder (sub-folders). You have to go to that folder manually. Any ways I manages to rename my sub-folders too by spending some time:))
