Specs: Windows 7
I cannot open any .exe files. However, I did try to open them with notepad and the first readable sentence (the rest were symbols and quite a lot of them) was "this problem cannot be run in DOS mode. Is there anything i can do about it?

Win7 doesn't support DOS. Are you attempting to run an old DOS exe?

YES, you can explain better what kind of files you are trying to execute since .exe are program files holding binary instructions to feed the processor.

From what you report I can presume they are legacy Win 3X executables (so 16 bit code) and you are running Win 7 64 bit that doesn't support any more those executables. This reading "cannot be run in DOS mode" a warning issued when Win 3X applications were launched under plain DOS (80s of past century). Just a guess, more info needed.

I think he has an association issue. There are a bazillion posts on that subject.

EndlingVinnie you don't open exe files you execute [run] them hence the extension EXEcute.

As Jefro points out you have been malwared/infected so your file association for exe is wrong.

Lots of fixes on the internet of which NONE have you trying to run the file in a command prompt or opening them with notepad.

Answers are only as good as the information you provide.

Do you mean that you can't run exe files? If so try the EXE fix here:

If it helps, then immediately run your AV scanner. Also try running MalwareBytes freebie as this often finds and fixes what AV's can miss.
