I have the same problem. I DID however find a fix. Its quite tedious but it works. You have to go into the console and click on each guard individually. Each guard you click on, type "setav aggression 0" and then "resetai" (Without the "). Once you do this, I don't know if they will ever attack you again at all or if it goes back to normal, but it stops them from hunting you for no reason.
