I'm running Windows XP, Home edition, version 2002, SP3. I just ran Spybot and it found this in my startup files. It listed a series of .exe files it might be (system32.exe, pathex.exe, svchost.exe), but when I did a search for them, I found none of the ones listed. The entry itself is blank.
My system has been bogging down, and my browser (both Firefox and Chrome) crash regularly.
