Windows 10: super slow and had 4 virus-malware in hundreds

its asus note book pc Q504U stock with 1tb drive
boot time maybe 10 minutes.
ran sfc scannow and it passed ok.
ran dism restore health, recheck sfc scan now and it passed.
upgraded to win 10 1803 to 1809 which took 6 hours and it succeeded, win 10 defender said no malware.
Ran malware bytes and found 208 removed ok.
Ran Hitman Pro and it found 4 virus and loads of pup, quarantined all.

so far not much has helped with performance, but getting rid of the malware sped it up a little, now 10 mins to boot to working desktop. Loading Chrome takes 4 minutes, then a minute to load a web page. Clicking windows menu at first load takes several minutes to see anything. it was never this slow except for last 6 months. this has basically become almost unusable. So what can we do?
