If you mean 80-100 seconds from power-on to windows login and Internet home page loading, then you really don't have too much to complain about. Windows7 laptops and older (going back to Windows XP) should do this within 5 min. or they need expert service. 3 min. or thereabouts, and now 20-30 sec. less than that puts it into the 2-3 min. load range, which is better than most laptops ever achieve, even right out of the box! 
It sounds like you are used to running a really clean computer, with very few programs loaded, and you load up each of the programs you run manually when you use them, and that's fine. Me, I run 30 or 40 programs on startup, and it's takes me a little longer, but I don't have to wait when I need to open a program up to use it. (six of one, half-dozen of another).
Bassfisher mentioned the McAfee being a resource hog and that's true, as it uses around 250-300% of your CPU resources when loading and scanning *by comparison, Norton products use 360%*. That's the best protection on the market by the way.
But I would gladly be willing to have a quality subscription-based product protecting my computer and sacrifice a few seconds or minutes to avoid having a nasty spyware-virus infect my computer and have a hefty $100 or better repair bill to fix it! But, that's just me. Oh, by the way, I go out looking for new viruses on the web to report them, you probably do not.
Avast is the only free product that does a reasonably adequate job, but it cannot stop many of the viruses that I catch in the wild on my systems here; but I'm looking for trouble, most users are not. I work in conjunction with the AV companies to try and stop viruses and to produce antidotes. So, using the McAfee if it's current, working and up-to-date is a time-based sacrifice you may have to learn to live with.
I have a number of customers who don't believe in using security protection programs on their laptops, as they think it's a scam. Those folks keep me in business! It's like driving without Auto-Insurance; it's a money-saver; until you get caught and have a serious accident that mames or kills someone.
The other thing you might try, if the bootup time really bothers you that much is to backup all your data to an external hard drive, flash drive, or CD/DVD discs and run the Factory Recovery Windows Disk that came with your laptop. This will restore it to what we call in the biz "Out-of-Box" condition. It will format the hard drive partition that contains Windows, (make sure you choose the Format option)and replace Windows7 and all the installed programs from Dell that originally came on the laptop. Reboot the laptop, and time the power-on to Internet-home-page loading time and see if it improves, stays the same, or gets worse.
If the time substantially improves back to your original 35-40 seconds timeframe, then some program or programs (possibly including the McAfee) are slowing your system down, which as I said above is the price you pay for having a good quality security protection program running. *MAKE SURE YOU DON'T RESTORE YOUR DATA TO THE NEWLY RELOADED WINDOWS CONFIGURATION AS IT MAY CONTAIN VIRUSES THAT ARE CAUSING YOUR SLOWDOWN*.
Lastly, if after my Windows Restoration instructions are followed, and your bootup time significantly increases, say to 5 min. or more, you may be running into a problem of gradual hard drive degradation. If your laptop is running Windows7 it is between 2 and 4 years old; most hard drives in laptops fail from year 3 onwards. At this point, you should consider taking your computer into a local computer expert, preferably someone who has an A+ Ceritifcation Professional License to work on your computer. They may recommend you replace the hard drive, and they can run diagnostics to make that determination for a small fee. Most laptop hard drive repairs cost between $90-$170 in my area, that includes the cost of the new hard drive. Given that information, most people will wait until the hard drive catastrophically fails, and then go spend the money to repair/replace. The Cow is out of the Barn at that point. But, again, that decision is up to you.
It is quite possible that that is your real problem, and running all these various performance programs cannot fix a hardware problem.
Food for thought.

:-D
. Yeah I totally Agree with you. I also believe 80-100 seconds is a pretty fair time. Cause like 6 years ago, my old computer (XP) used to take upto 8-10 mints to complete its boot !! 
I usually never keep /installs un-wanted programs on my computer. I've my subscription of McAfee upto next April, so sometimes I'd stick with him till then 
It was very long ago, after that incident I put away my theory. ;-)
) and also Good AV's like Kaspersky is available <$10 in my place!
