well....no...that doesnt sound right at all. Yes it is normal for Rogue Killer to close d7ii, and its also normal for it to reboot after it finishes scanning, but not just from downloading. Is this only in auto mode? see what happens if you just double click it to manually run it. If it runs fine manually reconfigure what apps/functions you have set before rogue killer is ran. If it doesn't run manually it sounds like the program itself is somehow corrupt or an invalid command is being used with it....since recently Tigzy has been changing things around with Rogue Killer it wouldn't surprise me.
Lastly if none of that works download directly from adlice.com (rogue killer website) make sure it will run directly (just in case the website version is corrupt or local is outdated) if all good there then simply make a copy of the rogue killer config.....oh this is getting long already, if it doesn't work after all that just pm me and i should be able to help.
If I had a world of my own, everything would be nonsense.....Who in the world am I? Ah, that's the great puzzle. I'm afraid I can't explain myself, sir. Because I am not myself, you see?
