First off, give me the specs of this laptop, how much memory is installed and what processor is in it. I'm guessing you don't have enough ram and with everything running at bootup is really slowing you down, Mcafee would be the big thing slowing you down.
You have a lot of items that is running at bootup that can be disabled. Please use the msconfig utility to stop these programs from running at bootup. Click on start, click on run, type "msconfig" without the quotes and click on ok. When the utility loads up click on the startup tab and then uncheck the items that correspond with these entries. After unchecking items, click on apply, then ok and reboot your computer.

Also I recommend downloading and running malwarebytes and posting a logfile from it. Follow the steps here....

Run malwarebytes first, and then hijackthis again and post both logs back here.
