Most of those cleaning programs are junk, especially MacKeeper.

If your friend got onto your computer and visited a bunch of adult sites, then I would recommend something like OnyX, doing ALL the cleaning and maintenance aspects and rebooting, perhaps followed by a Disk Utility Erase free space.

Easily optimize your RAM for a real performance boost.

Device running slowly? It’s time to clear out old memory and boost available RAM—for free, with these optimization solutions from Avira.

Avira Free System Speedup

Understanding RAM and performance

Random Access Memory (RAM): Three little letters and a very large impact on system performance.

What is RAM anyway?

When you start a program, that file is retrieved from the hard drive. It’s then placed in RAM temporarily while you're working with that program. RAM is your digital “workspace.”

RAM and speed

The more RAM you have (and the faster that RAM!), the faster your programs will run. RAM is used up quickly if you’ve got lots of software installed—especially if many different apps fire up at once when you start up.

Don’t buy more RAM. Boost your available RAM:

Identify problem apps and uninstall them. Disable apps that start unnecessarily when you boot up. Get a trusted system optimizer/RAM cleaner (like the one below) to do it all for you

System Speedup for Windows

Discover an industry leader for more stable, turbo performance:

Helps you “lose weight”: Rids your system of all the clutter it no longer needs (system cache, temp files, internet junk, duplicates, etc.).

Tidies up your browser: Removes all online traces and temporary data from every browser to declutter your machine and shield your privacy.

Cleans your registry: Invalid registry entries? Remnants of uninstalled software? System Speedup analyzes the problems and clears them out.

Optimizer for Mac

Fire up the app, do a scan, and see it remove the clutter that’s slowing you down.

Does a spring clean: The Junk File Cleaner deletes unnecessary files and browser junk. The Duplicate Finder clears copies of photos and other files.

Gets rid of monsters and dinosaurs: It spots XL and old files that are hogging your resources.

Speeds up start times. Helps you speed up by around 25%, as it limits the number of tasks performed while Windows loads.

Optimizer for Android

Turn even an older Android into a lean, mean mobile machine.

Boosts speed: Optimizes processes for faster start-ups and greater performance.

Cleans up fast: Clears your cache junk and duplicate files on your phone and SD card for a feather-light, speedier experience.

Manages apps: Gives you instant insight into how much space each app uses so you can uninstall the worst offenders with a tap.
