I can no longer open up a .txt with Window's notepad or run notepad.
I tried to run notepad by typing it in the run dialog box from the start menu. The usual explorer.exe is tying to load notepad.exe dialog box came up. I clicked cancel (don't remember if the 'remember this decision' check box was selected or not <---irony
) after waiting about 5-10 seconds. After this, I got the usual 'notepad is not a valid Win32 application' message.
After this, I tried clicking on notepad from the start menu and clicked remember this decision to allow it to run. I still could not run notepad after this so I restarted the computer.
After restarting I could run notepad and open .txt files. However, yesterday I tried opening a .txt from within a zip folder (using Window's default zip folder viewer) and I got the 'notepad.exe is not a valid Win32 application' again. I tried opening a .txt file not in a zip folder and this didn't work either (don't know if trying to open a .txt file in a zip folder triggered anything bad). I restarted the computer again and still can't open notepad or a .txt file.
I'm using v. 126.96.36.199, initially selected 'scan my computer for known applications' or whatever, Windows XP SP2 32-bit, McAfee Virus Scan v.10.0.20, Windows Defender, and have a single core 1.7GHz P4 processor.
