SLOW Boot - since CCleaner install

CCleaner is GREAT... but since installing couple days ago I have noticed VERY slow boot up time. Checked "Start Up" programs, etc and don't see anything new. Have booted several times since the install and it remains SLOW, SLOW. (Didn't have a slow boot before) Just before the icons appear on desktop is where there is a very long delay. Once it fully boots everything seems fine... and it seems that CCleaner has definitely increased my speed on everything else. Anyone else experience this? If so, or not, can you give me some ideas as to the possible problem and a fix? Thank you.

ADDED: I just saw that the "command-line parameter" (shows in Options >"About")

says it is "AUTO- Runs the cleaner upon loading and then closes the application"

SO... that is propbably reason for slow boot. How can I change this? Have made

changes before re manual or automatic upon booting but don't recall how to do it !!!

Open CCleaner

Click options/ settings/ uncheck the box that says.... Run CCleaner when the computer starts.
