A. THE BUG
Can U reproduce the problem & if so how reliably?:
Happens all the time.
If U can, exact steps to reproduce. If not, exactly what U did & what happened:
Whenever I try to shut down or reboot my computer it all seems to freeze at the last farewell screen, when it’s just blue background and message “Shutting down”. It never took longer than a couple of seconds before, now it just takes forever. Well, I left if overnight once, it was still “shutting down” in the morning. So now I just have to kill it off with power button, which is not very cool.
One or two sentences explaining what actually happened:
After upgrading to CIS 7 from CIS 6, my computer can’t shut down correctly, stopping at the last farewell screen.
One or two sentences explaining what you expected to happen:
I want my computer to shut down normally >_<
If a software compatibility problem have you tried the conflict FAQ?:
Comodo is the only security tool I have, never failed me before 
Any software except CIS/OS involved? If so - name, & exact version:
No
Any other information, eg your guess at the cause, how U tried to fix it etc:
My guess is that windows is trying to shutdown CIS-protected process, like firewall itself.
B. YOUR SETUP
Exact CIS version & configuration:
7.0.317799.4142
I only have firewall, never installed any additional antivirus or promotional features, that went with your setup program. (That’s the kinda guy I am, I only install what I really need.)
Modules enabled & level. D+/HIPS, Autosandbox/BBlocker, Firewall, & AV:
Firewall and HIPS only, autosandbox disabled, no widget too.
Have U made any other changes to the default config? (egs here.):
No.
Have U updated (without uninstall) from CIS 5 or CIS6?:
I believe I had CIS6…
