Windows 7: Security Warning on all Executables

Security Warning on all Executables

I just installed Windows 7 64-bit for the first time, and after installing all the "important" updates, I'm having this problem where all executable files (.exe, .msi, .bat), as well as shortcuts to .msc files (but not the files themselves) are prompting an "Open File - Security Warning / Do you want to run this file?" conformation (see attached screenshot).

I got it mostly under control with a combination of enabling "Launching applications and unsafe files" in the Internet Security Zone settings, and adding the above file types to the "Inclusion list for moderate risk file types" in the Group Policy Editor.

This has worked when launching files directly, but many installers extract their executables to the temp folder, where the're being blocked from running.

I'd love to get at the underlying cause of this problem, but I'll accept any other workarounds anyone can offer.

Hello Xichael,

This is the normal warning message that you will get when you try to run or open a file that was downloaded from the internet or saved to your computer from an external source.

Normally, you would just need to unblock the file as in the tutorial below first to stop this message for the file.

Open File - Security Warning : Unblock File


For the workaround that you mentioned:

Open File - Security Warning : Allow or Prevent to Unblock File

Hope this helps,
Shawn

This is not the usual warning you're thinking of. I'm familiar with this popping up for files I've downloaded, but this is happening with every executable file, including those installed with Windows - Internet Explorer or Notepad, for example - as well as programs I'd previously installed and run without incident - Chrome, Komodo Edit, etc.

As I mentioned, this started after first running Windows Update, if that's any clue.

In that case, see if this may work for you instead. It uses the Inclusion list for low file types option instead that usually works better.

This does solve the problem for when opening files directly, but for installing apps that extract to the temp folder, the problem remains.

For example, when installing Jing, it extracted an .msi file, but failed when attempting to run it (see attached screenshot). I could, however, open the temp folder and run it myself.

I just tried installing Java as well, and it doesn't even get as far as extracting itself (2nd screenshot). Not sure how to get this installed.

I really appreciate the help, Shawn.

Well, that's good. We got it half way sorted.

You might see if this may be able to help with that error. It's for XP, but still applies to Windows 7 as well.

I had actually tried that, but it had no effect.

I am truly bewildered. I just went through and uninstalled every update (except a couple which didn't have the option: KB2533552 and KB976902). It had no affect.

I then created a new user account, which has the same problem.

I tried installing Microsoft Security Essentials. It failed as well, giving me a link to this article for a remedy which did not work.

I suppose I could do a repair install, but I'd rather not have to. I don't have much faith that it would work anyway.

Should I just go back to my trusty 32-bit? I had hopes of getting more RAM soon, but 64-bit is proving to be a debacle.

But why? What has happened to my system? I've never encountered such an impenetrable conundrum.

I think you may just have a bad install caused by something.

I would usually recommend trying a system restore using a restore point dated before this happened, but since you just installed Windows you may not have one and a clean install of either 32-bit or 64-bit may be the option to do instead.

Have you tried setting the UAC to "Never notify"? I got so annoyed with its interfering that this is what I ended up having to do.
