Clean install, Disk clean up

[Camera_Guy]

Okay so! I did a fresh install of WIN 10 night before last and had one small problem. I never set it to format my drive ( I had malware and other nasty stuff ) So on the fresh install of windows I had to run the disk clean up to clear 400GB of the old OS files. Everything looks to be good now but there are still a few files left over from the old install. My question is could any of the left overs that were not cleaned up by disk clean up still cause a problem or contain a virus/malware? And also could that at all be why I still have like 8 minute start up times? Once its booted up I still can't do anything on the desktop for like 5 minutes. I though the reinstall would fix that but I guess not.

I would have formatted to ensure the eradication of the virus and a true clean start.

Have you tried searching for malware with anti-malware softwares?

I had not realized it until it was to late so... Do you think I should just reinstall it once more and be sure to format this time?

I would that will guarantee all of the virus is gone.
