Just like the title says, I have installed a fresh copy of Windows 7. I had lost my recovery discs, so I downloaded the official .iso image from, http://www.mydigitallife.info/windows-7-64-bit-x64-direct-download-links/ I downloaded Ultimate because my university gives it's students Windows 7 Ultimate license keys. So I figured why not! So after I create a Boot USB, I install the OS. Everything goes smoothly, until I open up C:\Windows\system32\ and I see that "Rundll32" still shows a page icon.
I checked all my desktops and they all have the same image for Rundll32!
At this point I am panicking because I don't know if all my computers are infected by malware or if something else is at fault.
My Rundll32 file is sitting at 44.5 KB.
At this moment, I am installing BitDefender, TDSSKiller, Malwarebytes, and completing Windows Updates(Obviously, I am not typing this on the infected machine). I will update this post if the programs find anything.
Edit: I think I posted this in the wrong thread. I will post this in "Windows 7" instead.
Edit: I think this is the right sub-forum.
