1.	Solve : "Open With" window/can't run the programs.?
Answer» I removed a virus from my PC but, now I get that "Open With" WINDOW, and can't run programs. like Firefox etc.At least not without selecting the program I want to open it with each time. I'm running Windows XP Home Edition. I have TIRED going to http://www.dougknox.com/xp/file_assoc.htm already and I did the below steps but,no luck. [Look to the "EXE File Association Fix", and download the .ZIP file to your computer desktop.. Once there, unzip the file, then double click on the "xp_exe_fix.reg" file that is inside, CHOOSE "OK/Yes, when it asks "Are you sure?".. Restart the computer.. It should now run those problem programs and Control Panel icons.] HELP?
