There's a lot of software out there for optimizing your computer's performance, protecting you from malware and viruses, and generally "cleaning up" your system. Unfortunately, a lot of this software is loaded with adware, bloat, or even viruses that do the exact opposite from what you wanted. There's a huge market of uninformed users who simply do not know better, and it's the same people who don't know how to keep their computer clean & fast in the first place.
Here we are going to go over a couple of proven, free, and useful programs for keeping your computer fast, clutter-free, and safe.
Contrary to what the website says, Malwarebytes does not make antivirus obsolete. However, it does do a great job of finding and removing malicious software, and it pairs very nicely with a light antivirus software (see part 3 of the Computer Hygiene series for more info.)

CCleaner, originally Crap Cleaner, is a multi-purpose utility for freeing up drive space, securely erasing files, correcting registry errors, viewing system information, configuring startup applications, and much more.

Using CCleaner:
For cleaning up old files: use the Cleaner tab to Analyze & Run Cleaner to delete old files taking up space on your system. A lot of these files are cached information, including auto-fill information like user names and passwords, so don't be surprised if you have to log back in to sites after deleting those files. Take the time to read through the checkbox options to see exactly what you're deleting!
For backing up/correcting the registry: use the Registry tab and scan for issues. When fixing the issues, always back up the registry. You may have to run this multiple times before there are no more issues.
For uninstalling programs, changing startup programs, and more: use the Tools tab and explore the various things you can do. Don't run anything that you don't understand completely or you will risk permanently deleting important data.
