Completely Inaccurate

Nothing about the stats are accurate. One day it went from saying I had 10-15 visitors to 500 visitors and over 1000 visits and it has consistently been this way for a couple days. This is great except when I check that against my hits on posts and pages it doesn’t add up. My site has also been really slow since this has happened. I’ve deleted the app and it’s file from control panel. Good luck to anyone else with this. It started off seemingly accurate but lately it’s been ridiculous.
