Hum.exe - programs not launching on Windows 7

Question

After a infection by what seems to be a malware / trojan, a windows 7 doesn't start its executables but rather opens the "select a program for this extension" list box, with the extension being .exe

Any way to repair this? I'm thinking about poking in the registry but i would like to know if somebody already encountered that before rushing in the system's bowels

Answer 1

Yes. Here is a link to the patch/fix. Just download and run. Here is the manual method:

Click Start, Run and type command
Type the following commands one by one:
cd\windows
regedit

If Registry Editor opens successfully, then navigate to the following key: HKEY_CLASSES_ROOT \ exefile \ shell \ open \ command
Double-click the (Default) value in the right pane
Delete the current value data, and then type: "%1" %* (ie., quote-percent-one-quote-space-percent-asterisk.) Navigate to: HKEY_CLASSES_ROOT\.exe
In the right-pane, set (default) to exefile
Exit the Registry Editor.
