i'd suggest wiping the SSD before installing the new OS or re-installing the OS and wiping it 3 times. I clone my OS to a backup SSD and whenever i got hit with a bad malware, virus or whatever, instead of chasing fixes it was easier to just clone the backup back to the OS drive/
Then two times in a row, when i would clone the backup back to the OS drive, the same virus or worm or whatever it was would still be there. FInally, a retired MS engineer customer of mine called in, and i asked him wtf re the issue/ He said a lot of times the cloning software or even windows will, when writing to a disk, see the same file with the same name, date etc, it would skp over it and go on to the next file.
That explained the virus showing back up as well as why cloning times would vary from one clone to the next. Now before doing a new clone, i'll wipe the target disk 3X and then clone, and same if i'm cloning back to the orig OS disk
fwiw
