It performs some useful chores, but any program that tells you it's your personal computer expert then says you need to install Google Chrome and that now is the time to buy a new laptop raises a red flag.
Not that Chrome isn't a worthy browser, but there's one video downloading add-on that makes Firefox more of a draw for me. So, skip the Chrome advice. And if you just bought a new laptop like I did, skip that advice, too.
On the other hand, TechieBot will download the free Microsoft Security Essentials and install it for you--something I do recommend to most users.
TechieBot removes unnecessary startup items, but can be overzealous. It looked in the "run once" section of the registry and recommended that I disable a couple of uninstall cleanups before they had run. Had I let Techiebot do its thing, I would have been left with unwanted detritus on my system. Techiebot will also clean up various temporary files.
I'm not certain TechieBot is worth a look. It performs a few useful tasks, and the general advice is good, but software that recommends products makes me uncomfortable, even when the recommendations seem reasonable.
