Unable to show EXE file extension

By thong_cheekang ·
Dear all,

My laptop is installed with win xp and I have a strange problem: I wanted to rename an executable (.EXE) file into another file extension, but I can't get it done!

I understand the usual thing to do is to first go to Windows Explorer, click on menu entry "Folder Option". Then, under "View", we are to unclick "Hide extension for known filetypes", so as to reveal the extension for renaming.

However, for my case, some other types of file extensions appeared but not .EXE!

I understand the next step is to go to the tab "File types" and try to modify the file type behaviour from there. However, the file type ".EXE" is not even there for modification!

Does anyone has any idea why my laptop is behaving like this and any solution?

Thanks and Best Regards
TCK

Check of infections

By making sure that your AV Product is fully updated and that you have some Malware Scanner installed and Updated and then boot in Safe Mode and scan the system.

You should continue scanning till it is either clean or you can not remove something.

Besides whatever AV Product you have installed you should have Malware Bytes

Spy Bot S&amp

If you do not have a valid AV Product Installed AVG Free will do a good job

Or Avast Home Free both do a good job but you only need 1 AV product installed.

Windows? XP File Association Fixes
http://www.dougknox.com/xp/file_assoc.htm

Download Malwarebytes Anti-Malware, install it and update it and scan your Sysytem.
<a href="http://download.bleepingcomputer.com/malwarebytes/mbam-setup.exe" target="_blank"><u>Malwarebytes</u></a>

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform Quick Scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.

If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.

Is this what you need to do?

by Jacky Howe In reply to A couple of suggestions

To show file extensions, first open "My Computer", Then select "Folder Options" from the Tools menu.
When the Folder Options window opens, click the View tab. This will show the file and folder view settings.
One of the options under Advanced settings is "Hide extensions for known file types." If this option is checked, uncheck the checkbox and click Apply or OK. This setting is system wide, so unchecking this box will make file extensions appear in all folders.

LOL. You and I are going in circles.

I posted a link below, which you had posted much earlier. Now you have suggested what the OP claims to have done in the first place. Then again, I wonder if that setting shouldn't be looked at again, or be given the old "on /off, on /off treatment, which seems to work for some things.

it wouldnt hurt to recheck it. The on/off trick sometimes works.

The OP should check to see if show Hidden and System files are unticked as well.

Ah, that was the type of thing I was looking for :-bd

by seanferd In reply to Also check this link

Nice find. I figured, if malware will change media file extensions, changing executable extensions would make sense as part of an attack.

Good try but still not working

by thong_cheekang In reply to Also check this link

Hi Jacky Howe,

I tried both the solutions provided.

The first one didn't seemed to have any effects.

For the 2nd one, the entry "HKEY_CLASSES_ROOT\exefile" on my laptop doesn't have "NeverShowExt" as one of the values.

Thanks and Best Regards

Hi Jacky Howe,

Thanks for your reply.

I did try this standard way of making file extension appears, but it just didn't work.

Any other suggestions?
