It's better not to attach your logs, but copy and paste them in the thread instead.

Please make sure you disable ALL of your Antivirus/Antispyware/Firewall before running ComboFix..This because Security Software may see some components ComboFix uses (prep.com for example) as suspicious and blocks the tool, or even deletes it. Please visit HERE
if you don't know how.
Extra note: The combofix tutorial recommends to disable your Antivirus, in your case McAfee. For McAfee, I rather recommend to temporary uninstall it, because Mcafee causes a lot of problems with Combofix after reboot, this because McAfee enables again after reboot. So please temporary uninstall McAfee first, then reboot and then scan with Combofix.
