msconfig startuupmsconfig

System Configuration opens the “General” tab, where you will need to select the circle next to “Selective Startup.” Next, move to the “Startup” tab and go through the list there: select all the programs that have an unknown manufacturer and disable them, because programs with unknown manufacturers are almost always malware. Restart your computer to close any currently-running versions of the malware.
