rkill.com - This suspends all malicious and third party files running in the background in order for the following tests to be able to run without being blocked/interrupted by some shady software, don't reset PC after running this unless you ran all your other tests
Malwarebytes Anti-Malware - Probably the best overall anti-malware software around, has been like this for a long time, the free version is the same as the full version, only doesn't allow active protection (which you honestly don't need if you know what you're doing). MAKE SURE TO ENABLE SCANNING FOR ROOTKITS IN SETTINGS!
ADWcleaner - Another software by Malwarebytes, looks for toolbars and adware that comes with installs and deletes it. The best of its kind
Malwarebytes Junkware Removal Tool - Another one by MB, looks for PuP and other useless stuff.
Hitman Pro - If you want to be really 100% sure there is nothing left after all the scans, Hitman Pro is a really good tool as well. Just please check what you're putting to quarantine, sometimes it gives false positives (gave me a "Suspicious" flag to Punkbuster)
After doing these, you can restart your PC.
Unchecky - You know when software keeps annoying you with downloading "The Best Browser Emojis!!1!1!1"? Unchecky automatically disables all this stuff and warns you about it.
CCleaner / Windows' Disk Cleanup Tool - To clean other unneeded stuff, in case of CCleaner disable all the active monitoring stuff in settings, it's annoying
Auslogics Disk Defrag - Watch out for the software that comes with it. Use Unchecky or make sure you didn't allow downloading the software. This is self-explanatory, defrags your disk, do not use with SSDs, SSDs don't leave fragments do leave fragments, but it doesn't affect them and defragmenting them decreases their lifespan.
WinDirStat - Software that scans your drives and shows you what is taking your space in a very organized matter, doesn't hurt to delete the 300GB worth of torrents!
Revo Uninstaller - Scans for leftovers after deleted files that are not needed. The files won't be large, but there's lots of them and they make a damn mess.
Next you might want to make sure your GPU drivers are up-to-date
AMD
AMD Clean Uninstall Utility - Deletes all your GPU drivers and cleans the leftovers after them
AMD Drivers - Do so after using the CUU
NVIDIA
NVIDIA doesn't have official disk removal utility, but you can use DDU - Deletes all your GPU drivers and cleans the leftovers after them
NVIDIA Drivers - Do so after using the DDU
JavaRa - Deletes all your Java versions so you can fresh install the newest one, helpful if you're getting error 1603 like me when uninstalling.
