Unexpected Change of File Format

Posted by Kuntal Gupta on April 5, 2009 // Leave Your Comment

Well recently i saw many issues with the problem stating that on a user’s PC a few files (say their mp3 collection) changed completly to another format and looked like a JPG / AVI One (Only the ICON) , So what to do in such cases ?

Explanation : There is a possibility that some malware has RENAMED those mp3 files (in this case ) with the jpg / avi extension .

Well the users should try the following , it works for most cases (100% success rate till i experienced).

Just use program like Antrenamer to revert the file name change back to normal.That is they just have to change the file extension from jpg to mp3.

Before Doing it : They can check whether this “Renaming” is the case Openup My Computer -> Tools -> Folder Options -> View -> Uncheck “Hide extension for know file….” and click OK. Now they will be able to see the file name extensions , so just go to the File which has become jpg from mp3 and change the extension back to mp3.And play it , if it plays correctly then AntRenamer could do the job. And if playing fails then , they should get a Good AV and do a scan in Safe Mode. Backup their system and Perform a Clean Install.

[ Download Antrenamer ]
