Windows 7: not a valid win32 Application....

Windows 7 Home Premium 64 Bit not a valid win32 Application....

Hi guys,

I'm in need of some serious help, my computer is acting extremely weird when opening .exe files which it has never done before. Whenever I try to open ANY exe file I've downloaded it tells me the application is not a valid win32 application. Which I don't understand. I've done a virus scan and it found some Trojans and viruses, and I deleted and disinfected and rebooted the computer. I also went into CMD and did a scan that fixed something within the system files after doing a little bit of research on it. It rebooted but still nothing. It gives me the same annoying error. I tried downloading Malwarebytes Anti-Malware but it also gives me the same error as with other setup and exe files. Right now I'm stuck with Microsoft Windows Defender in scanning. I tried downloading from Internet Explorer to see if it was from Google Chrome and still no luck as well. I feel like I'm stuck in a very deep technical error hole. Any help would be greatly appreciated. Thanks for the help.


There might be some viruses left, because the scan did not finish due to the monitor not responding, so I had to shutdown and reboot. But I'll try again and wipe out any more I find if any.

the viruses screwed up your file associations from the sound of it.
Go to the below linked tutorial and use it to ensure you exe file settings are correct.
Default File Type Associations - Restore
(just scroll down to exe)

it does sound like you've done a decent job of removing the malware, so hopefully all you need to do is fix the association.
