I have just cleared XP Total Security 2011 off the system but now any attempt to run a program from the list or desktop opens the Open With dialogue box. The program is there but refuses to run. Interestingly, running explorer from the hotkey (win + E) works fine. Is there general setting that has been changed by the threatware and if so, where is it? I have tried the usual windows repair tool but no improvement. Grateful thanks up front!
