Re: i think i may have some kind of virus...
This could be a trojan that doesn't allow you to run .exe files
You could try starting up in safe mode, simply keep tapping f8 from the moment that the computer is starting up, till you get in the boot menu.
Then from the boot menu select 'safe mode with networking'.
Start up, try to download malwarebytes again etc, it will probably work.
Do full scan, remove everything and start up in normal mode again, and re-scan.
Other thing you can try is after downloading malwarebytes, change the name of malwarebytes.exe to iexplore.exe, making the virus think you're opening internet, most viruses allow you to open internet.
