You can easily go ahead and block the file it self so it is no allowed to be run by anyone or everyone based on the rules. You do this through group policy. Here is a short tutorial: -specific-programs-in-windows-7/
I left my laptop on while I was out for about an hour because I was in the middle of something. Came back and I had an alert by my antivirus (Kaspersky), that I had a Trojan (Script). It had the option to remove the threat, and I had clicked to remove it, but it didn't work. So I attempted to shut down my PC but it was not allowing me to shut down when clicking to shut down.
I opened the system tray in the bottom right to see if I could open my antivirus again and noticed that the windows security icon was red, and when I went to click on it, got an error message. I don't remember exactly what it said, but it was along the lines of "you may not have permission to open this". I also attempted to open some photos but nothing would open.
So I force shut down my laptop by holding the power button, and when I turned it back on I had the same issue, Kaspersky popped up straight away, nothing was working again, but this time the threat removal worked. Kaspersky then did some system repair process to revert anything it thought the virus/malware may have damaged.
I restarted the PC and everything seemed normal. Ran another virus scan, and luckily, no threats. I also then downloaded Malwarebytes and got the free trial and scanned, no threats detected there either.
I then investigated where I may have gotten this virus or malware from, as I am very careful with the websites I visit, and programs I download. I had not remembered downloading a program for a very long time so something seemed off. I checked the quarantine centre in Kaspersky and opened where the file was located. It was located in a Google Chrome extension folder. The file had obviously been removed but the folder it was in was still accessible. I had not downloaded an extension for a long time. The only ones I had were an Adblocker, the same one I have used for years, and Kaspersky Protection extension for Chrome.
I went and opened extensions on Chrome, and to my suprise there was a new one, that I have never used before or seen. It was also disabled. The extension was 'UltraSurf Security, Privacy & Unblock VPN'. I do not remember ever installing this. I deleted the extension, and sure enough, the folder the threat was located in was gone.
Commonly, corrupt or missing ultrasurf u1204.exe files cause these EXE executable errors on Third-Party Application software launch. A large percentage of these file issues can be resolved with downloading and installing the latest version of your EXE file. After the problem file is replaced, running a registry scan can help clean up any invalid ultrasurf u1204.exe, file extension, or other file path references which could have been affected from a previous malware infection.
Placing the newly-downloaded ultrasurf u1204.exe file in the right directory (where the original file resides) will most likely resolve the issue, but you should test to make sure. Test the outcome of your replaced file by opening Third-Party Application and seeing if the error message is still being triggered.
These EXE error messages can appear during program installation, while a ultrasurf u1204.exe-related software program (eg. Third-Party Application) is running, during Windows startup or shutdown, or even during the installation of the Windows operating system. It's important to note when ultrasurf u1204.exe issues happen, as it helps troubleshoot Third-Party Application problems (and report to Windows Software Developer).
If none of these download link works, let me know and I will host Ultrasurf full set up on any free file hosting site and you can download it from there. Or you can use any of these VPN clients to get ultrasurf from official download repo.
As, I mentioned above if your Internet connection requires you to set up proxy settings,
