My test Win32.Sality.MBR+Hardware Malware etc. ( infected master boot record )

Remove Sality (Win XP ,Vista,7,8,8.1,10)

first delete MBR malware ( BIOS settings Mbr )
Bios f11 USB format delete all disks

New version Sality founded at 2015 ( in Turkey 2015-2019 %3-5 )

When using VirusTotal it is always best to upload file unzipped … meaning you upload the file inside the zip

Reason: all info behind the “details” button will be for the zip container and not the file inside, so details info is skewed

also when uploading files to VT note scan date at top right, if old (somone has uploaded same file) click on rescan for fresh result … i have rescanned now :wink:

see my attached screenshot

zula.exe is very old and low detection score, so possible false positive … the other file is detected by avast
