So you got one of those great little virus’s going around. You were able to clean it off after a bit of time and gnashing of teeth. However now you cannot launch any applications or more specifically any executables (.exe)
Fixing the association settings using Registry editor
Click Start, Run and type CMD
Type the following commands one by one:
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:
*Interestingly some virus’s have changed the full path of default value to c:usersHomerJSimpson<yourUserAccount>appdatalocalhappyvirus.exe /runas “%1” %*
In the right-pane, set (default) to exefile
*Interestingly some virus’s have added things like “sfcfile”
Exit the Registry Editor.
Fix with a com executable
You can use a com object to run the fix
reboot and all should be happy. At least with Executables.
Special thanks to Ramesh for giving me the idea on how to do this.
