asked on

windows xp - everything asking what to open with, example regedit.exe choose program to open with

i have a windows xp system that had a pop up virus.
do not know which one. it did hijack the system - saying purchase anti-virus.
other than that, nothing would work in windows.

had my friend run malwarebytes. restarted computer.

now when you click on system restore for example, it says choose the program you
want to open this file with box.

anyone know what this is and how to fix other than a complete rewipe.

thanks

Open a cmd prompt (click RUN and type cmd, then hit Enter) and type - regsvr32 /i shell32.dll

If you experience this problem only when opening drives, it should be quite a simle process:
- Go to Tools followed by Folder Options
- Click on the File Types tab
- Find the association your having problems with, in this case "Drive", click on Advanced followed by Set Default.

this is all .exe files

example,
right click on my computer for properties = open box appears
try to open ccleaner.exe = open box appears

a note,

this does not happen in Safe Mode, only when running Windows normally.

Thanks.

Combofix downloaded the proper files I was missing and
repaired the registry.

I already had combofix and forgot to use it after malwarebytes.

Thanks Again!
