Apart from the malware that deleted Windows Defender there's also Floxif virus, so further scans will be needed after the FRST fixlist.
- Download Fixlist.txt and save to the folder FRST64.exe is in
- Run FRST64 and press 'Fix'
Please share the resulting Fixlog.txt
Delete the C:\FRST folder so that the next scan isn't detecting files in FRST's quarantine folder.
